System Features
LOGIQ 500’s Features
The LOGIQ 500 digital Ultrasound System is a high
performance ultrasound imaging system, intended for general
purpose applications.
The system provides image generation in B-Mode, M-Mode,
Pulsed, CW and Color Flow Doppler and Color M-Mode with all
transducer types. Digital architecture allows maximum flexibility
of all scanning modes and transducer types, throughout the full
spectrum of operating frequencies.
All transducers are precise solid state array devices, allowing
electronically controlled imaging with Phased Array Sector,
Convex, Micro-convex and Steered Linear probes. Use of solid
state digital designs allows a wide variety of scan parameters to
be optimized including focusing, scan control, spatial resolution,
temporal resolution and contrast resolution. The result is
consistent generation of finely detailed anatomical resolution
with excellent dynamic contrast tissue range and penetration.
System Features
LOGIQ 500 also features newly integrated specialized
processing for Flow Data acquisition. Doppler information is
displayed with low noise and clean spectral content to optimize
measurements of important flow parameters. Selected probes
can operate in Multifrequency Mode in order to Optimize
Resolution in B-Mode and Sensitivity to flow in Doppler and
Color Flow Modes.
The system display processor is highly versatile to produce the
optimal set of imaging parameters and display formats without
compromising important diagnostic information. Comprehensive
graphical displays allow rapid and easy placement of Doppler
sample volumes. In Color Flow Mode, combined B-Mode and
Color Flow images can be steered independently so that optimal
positioning is available in both modes.

3DvieW Mode
Overview
3DvieW Mode
(Option)
A 3D image can be rendered or constructed from the cine data
collected during a normal scan by using a process called MIP
(Maximum/Minimum Intensity Projection).
When the scan data is properly collected MIP images can be
used to display vascular structure using the Advanced Velocity
Maps. MIP imaging is not a real-time function, but a
post-processing function.
CAUTION
CAUTION
This 3DvieW option is designed for qualitative information only
and has no provision for any measurement or computation
ability.
No specific reconstruction resolution or accuracy is provided or
claimed for this option.
Since positional information of the original scan is not available,
all measurement functions cannot be performed on a MIP
image. Information concerning the front or back of the MIP
image may be uncertain.
Caution should be taken when viewing the MIP image due to
the fact that the algorithm used in the MIP process may
produce a skewness to the MIP image displayed.
NOTE: Consider all of the above cautions when using MIP
images to evaluate a patient. MIP images should not be used
for quantitative information but a qualitative supplement to all
other diagnostic data collected for that patient.

3D Option Techniques
Max/Normal
This technique takes the maximum intensity of each frame on
one projection line. No threshold is used.
3DvieW Mode
Min
Inverse
Gradient
Example:
compared to data in the second frame along that line. The
maximum is then compared to data in the third frame. The
maximum is compared to data in the fourth frame, etc.
This is available in B- or CFM-Modes.
This technique operates the same as Max/Normal. The
difference being the minimum intensity of each frame on one
projection line is used. No threshold is used.
This is available only in B-Mode.
This technique operates the same as Min. The value of the
result is inverted. No threshold is used.
This is available only in B-Mode.
Data in the first frame along a projection line is
This technique is a weighted projection method. A Threshold
value (Gradient Threshold) is used.
CFM-Mode (Gradient)
It is assumed that the anatomy of interest will have a higher
intensity level than the CFM Gradient Threshold.
For each frame the object region is filled with a fixed value
according to its frame number. The near frame takes a higher
fixed value, while the far frame takes a lower fixed value. The
value is changed by gradation.
After this process, a maximum intensity projection is made.
The result is an image with the near side of the object having
higher intensity and the far side having lower intensity.

3DvieW Mode
B-Mode (Gradient)
Shade
Almost opposite from CFM processing. It is assumed that the
anatomy of interest will have a lower intensity level than the B
Gradient Threshold.
The near frame takes a lower fixed value, while the far frame
takes a higher fixed value. The value is changed by gradation.
After this process, a minimum intensity projection is made. The
result is an image with the near side of the object having lower
intensity and the far side having higher intensity.
This technique is basically a maximum intensity projection.
However, this technique uses two thresholds:
Shade Object Threshold The value is higher than
the set threshold.
Shade Boundary Threshold The value, to be compared
to Object Threshold result,
is lower than the Boundary
Threshold.
3D Presets
Comparison will be made frame by frame after the above
thresholds have been met. If the two thresholds are satisfied,
no comparison will be made with the rest of the frame.
Using the Max/Normal method, lower intensity echoes in the
near frame will be masked by higher intensity echoes in the far
frame. The Shade Method makes it possible to show lower
intensity echoes in the near frame despite the fact that there
may be a higher echo projection in the far frame.
This is available in CFM-Mode only.
Presets in Set Up/Custom Display pages 9 and 18 allow for
choices in display and rendering technique.
All Parameters are not available in the soft menu.
Ensure that these presets are adjusted for the desired result.

Overview
3D–Surface Mode
3D-Surface Mode
(Option)
This option creates a projected image different from 3DvieW. It
uses images stored in Cine. The calculation used for the
projection is based on the transmission principle of light using
Volume-Rendering.
This function is available only in single B-Mode.
Refer to 3DvieW Mode section as needed.
CAUTION
CAUTION
This 3D-Surface option is designed for qualitative information
only and has no provision for any measurement or computation
ability.
No specific reconstruction resolution or accuracy is provided or
claimed for this option.
Since positional information of the original scan is not available,
all measurement functions cannot be performed on a
3D-Surface image.
NOTE: Consider all of the above cautions when using
3D-Surface images to evaluate a patient. 3D-Surface images
should not be used for quantitative information but a qualitative
supplement to all other diagnostic data collected for that patient.

Fetal Trend Management
Fetal Trend Management
Overview
Fetal Trend Management is an option to the LOGIQ 500 OB
Calculation package that enhances the user’s ability to monitor
the development of the fetus.
If patient data, measurements and calculations are saved
during the initial examination, this information can be compared
to results of follow up examinations. The OB Graph function
can be used to display the current data or combine the current
data with past data to show a fetal growth trend.
When previous measurement data is saved, all other
information, which is input at the Patient Entry Menu, is
retained. This information is automatically displayed in the
Patient Entry Menu on subsequent exams when the patient ID
is entered in the Patient Entry Menu.
(software option)
If the previous measurement data was saved on MOD, the
MOD must be inserted before inputting the patient ID in the
Patient Entry Menu.
Storing Patient Information
After an OB examination, the user can save the resultant
patient data to two different types of media.
The user can save the patient data to the system hard disk.
While this offers the convenience of not maintaining removable
media, the system hard disk’s storage capacity is very limited.
A Magnetic Optical Disk (MOD) would be the best storage
media. Although this removable disk must be maintained by
the user, it offers far greater storage capacity. Approximately
one year’s worth of information can be stored on one disk.
4–8
LOGIQ 500 Advanced Reference Manual
2276614–100 Rev . 0
Data Storage Estimations
If the following standard assumptions are made:
Work days/week = 5
Patients/day = 30
Diagnosis/patient = 5
Measurements/patient = 5
then approximately one year’s worth of studies can be stored
on the hard drive.
When hard drive capacity is reached, the message “Data is full.
Delete needless data” is displayed.
However, the average MOD can store more than 30 years
worth of data using the same assumptions.
Media Selection Preset Parameter
The user must choose the type of media that will store the
patient OB information. This is done in the Set Up/Preset
Program sub-menu page 3. The parameter is:
Fetal Trend Management
Media Selection for Fetal Trend : HD MO
Select HD for the system hard drive (limited storage space) or
MOD for a removable magnetic optical disk (much greater
storage space).

Fetal Trend Management
Saving Data
Before the diagnosis is complete, ensure that all patient
information such as Name, ID, Ref MD and EDC has been
entered. If it has not, use the ID/Name key to enter this
necessary information. Select the OB Graph function from the
OB Calculation soft menu.
Five additional commands are displayed on the OB Graph that
relate to the Fetal Trend Management option as shown in
Figure 4–3. These commands are:
LIST–ID—Displays a list by patient ID number.
LIST DAT A —Displays data for a specified patient.
TREND–BOTH—Shows data points on the OB graph based on
current and past data.
TREND–PRESENT—Shows data points on the OB graph
based on current data only.
SAVE—Saves Patient information to specified media.
CHANGE GRAPH—Changes the measurement value graphed
(performs the same function as in the basic OB calculation
package).

Type of Data Saved
Save Command
Fetal Trend Management
The type of data that is recorded during the SAVE function is:
1. Date and Time
2. Patient Name and ID
3. Calculated EDC or EDD
4. Measurement Author’s Name
5. Measured or Calculated Data
NOTE: To avoid any trouble in searching later, it is better to
have all patient information entered before saving.
Use the Trackball to highlight the SAVE command and press
Set.
If patient information has been entered, the patient data,
measurements and calculations will be saved to the designated
media (HD or MOD).
If there are similar files in the data list (i.e. same ID but Name
and EDC are different), the system displays the Patient List
Menu (LIST-ID). The user will have to select the file to which
the data will be added.
If the user does not input the ID, the system displays the
List-Data Menu. The user will then have to input the ID.
If the user does not input other patient data, the system
displays the List-Data menu. The user will then have to input
the patient data.
If more than one candidate is available on the list, the system
first displays the Patient List Menu. The user then has to pick
the proper file in which the current data will be added.
LOGIQ 500 Advanced Reference Manual

NOTE: If measurement averaging is turned on, only the
average value is saved. If measurement averaging is turned
off, only the last measured or calculated value is saved.

Fetal Trend Management
Save Function Messages
If patient information has not been entered, the message
displayed is:
If a patient ID number is not entered, the message displayed is:
“Input patient’s information:”
“Input ID:”
NOTE: The ID number is necessary or the SAVE function
CANNOT be accomplished. It is possible to save data without
a patient name or EDC but the information displayed with the
LIST–DATA function is limited.
If all of the data is the same as a file on the data list, the
message displayed is:
“Overwrite existing data? ‘y’ ‘n’. ”
where ‘y’ replaces the archived file with the new file.
‘n’ causes the system to do nothing. This cancels the SAVE
function request.
If the storage media is full, especially in the case of the limited
capacity of the hard drive, the message displayed is:
“Data is full. Delete needless data.”
Eliminating needless data will help to conserve storage space.

Growth Trending
Fetal Trend Management
The default command after the OB Graph is displayed is
TREND–PRESENT. This will display an OB Graph for the
current author/measurement selected.
However, after additional examinations, the user can recall past
data and display it with the current data to show a trend in fetal
growth.
When the user selects the TREND–BOTH command from the
OB Graph display, the system automatically searches the
storage media and gets the data and displays the OB Trend
Graph as shown in Figure 4–4.
Figure 4–4. OB Trend Graph
The system will search for like data displayed on the OB Graph.
If Hadlock BPD is the data displayed, then the current patient’s
Hadlock BPD data is used with the past Hadlock BPD data to
display the trend on the graph.
If the user wants to trend different author/measurement data,
that graph must be displayed first before the TREND–BOTH
command is selected.
An asterisk (*) is used to show the present data point on the
graph while the pound sign (+) is used for all past data points.

OB–Multigestational
Overview
Patient Entry Menu
OB–Multigestational
(software option)
The LOGIQ 500 offers an optional calculation package that
allows the user to measure and report multiple fetus
development. The system is capable of reporting a maximum
of four fetuses.
If the Multigestational Option has been purchased, an extra
entry appears on the Patient Entry Menu to the right of
“RefMD:”. This entry is called “FETUS NUMBER:”. The factory
default number is one.
Entering Fetus Number
It is generally during the first exam that the user recognizes a
multiple gestation. If during the first exam more than one fetus
is imaged, the user can use the ID/Name key to return to the
Patient Entry Menu and enter the necessary number of fetuses.
For subsequent exams the user enters the correct number of
fetuses when the New Patient key is used.
NOTE: Data Management Center transfer function will not work
if the fetus number is greater than one. An error message will
appear:
“Multigestation data transfer is not supported”
DMC data transfer will function normally if the fetus number is
set to one.

LOGIQ 500 Advanced Reference Manual
2276614–100 Rev . 0
Distinguishing Each Fetus
For measurements/calculations and report page displays, the
fetuses are labeled A, B, C and D.
Each fetus is distinguished on the report pages by its letter and
total number of fetuses. For example, a report page could be
noted as FETUS:A/3. This is fetus A from a total of 3.
Following this fetal number designation, the user can use
twelve characters to describe the position and twelve
characters to describe placenta location of the fetus. This is
displayed as:
POS: ############ PLAC: ############
Measurements/Calculations
During measurements/calculations, all measurements are
performed on fetus A first. The user then switches to fetus B
and performs the same measurements, etc.
OB–Multigestational
The user can switch between fetuses by pressing Blue Shift
and then N.
NOTE: A fetus change can be accomplished at anytime during
the exam. However, the Blue Shift, N function is NOT available
while a measurement cursor is active.
After changing to the next fetus, any measurements made will
be recorded and reported to the new designated fetus. Any
active measurement or calculation not completed will be
cancelled when the fetus number is changed.

OB–Multigestational
Change the Number of Fetuses
In the ID/Name function, the user can increase or decrease the
fetus number or cancel the Multigestational function. This
would need to be accomplished due to the demise of a fetus or
error in the definition of the fetus number.
Number Increase
If the fetus number has been increased on the Patient Entry
Menu, the message:
“Are you sure to change the number? (y/n)”
is displayed.
‘y’ will create the report pages for the new fetus.
‘n’ returns to the previous number.
If a fetus number increase is not available, the message: “Data
range over. Input proper data.” is displayed.
Number Decrease
If the fetus number has been decreased on the Patient Entry
Menu, the message:
“Are you sure to change the number? (y/n)”
is displayed.
‘y’ prompts the user to select which fetus to delete (A, B, C or
D).
‘n’ returns to the previous number.
The data of deleted fetuses is deleted for the measurement
result window and report pages. If the fetus number is reduced
to one, the multigestation function is cancelled.
After the decrease in fetus number, there is no need to adjust
the IDs (A, B, C or D) of the remaining fetuses. The same ID
for the remaining fetuses can be maintained and used.

OB–Multigestational
The Multigestational Option adds additional pages to the OB
Report displays.
Pages one and two of the Multigestational Option appear the
same as the Basic OB Reporting package; except, pages one
and two will be generated for each fetus. They will have the
fetus identifying information between the heading and
measurements. The fetal information displayed is:
“Fetus : $/% POS: ############ PLAC: ############”
$ = Fetal ID (A, B, C or D)
% = Total number of fetuses
The second to last page, depending on the number of fetuses,
is a summary of the measurements and calculations found on
page one. However, all fetuses (maximum of 4) are dipslayed
on this page. Since page one is different by region, page three
is also different by region selected (i.e. USA, European, Tokyo
University or Osaka University).
The last page, depending on the number of fetuses, is a
summary that compares all fetuses. The heading is different by
region. It contains the following:
Fetus Pos: Fetus position. This 12 character string is
common between pages 1, 2 and 4.
Fluid: An estimate of the amount of aminotic fluid.
Common between pages 2 and 4.
Biophys: Total biophysical profile score from page 2.

Advanced Cardiac Calculations
Advanced Cardiac Calculations
Overview
This option provides additional measurement, calculation and
report capabilities to the Left-Ventricular calculations not found
in the basic cardiac option package.
Added to the basic package is the Gibson, Single Plane–DISC
and Bi-Plane–DISC methods of LV calculations. A page of
measurements is also added to the cardiac calculation menu.
This page varies with scan mode. Additional scan mode
measurement categories are:
B-Mode Parasternal Long Axis (PLAX), Parasternal
(AMCAL option)
Short Axis (PSAX) Aortic V alve, PSAX Mitral
Valve, PSAX Papillary Muscles, Apical 4
chamber, Apical 2 chamber
M-Mode Left/Right Ventricles, Mitral Valve, Aortic Valve,
Pulmonic V alve, Tricuspid Valve
D-Mode Mitral Valve, Aortic Valve, Pulmonic Valve,
Tricuspid Valve
The number and type of measurements vary for each
calculation. The formulas used are shown in the calculation
specification tables in this chapter.

LOGIQ 500 Advanced Reference Manual
2276614–100 Rev . 0
Measurement Sequences
Each of the titles found in the first layer of the cardiac menu
consists of a sequence of measurements. The second layer
Sub-Menu consists of individual measurements/calculations
that can be performed in sequence or individually.
If the measurements are performed in sequence, the display
automatically returns to the first layer menu when all are
complete.
If the second layer Sub-Menu measurements are performed
individually, only those items measured are recorded on the
report page.
Sequence Philosophy
The primary philosophy of the cardiac calculation package is for
the user to select an item from the first menu layer. The system
then prompts the user to perform a series of measurements in
sequence. This measurement sequence can be modified by
the user if the factory sequence is not satisfactory.
Advanced Cardiac Calculations
Hints
This operation should not be confused with the Auto Sequence
top menu selection. Items programmed into an auto sequence
can consist of first layer sequences as well as individual
measurements. Together these form a sequence of
measurements and calculations that may be performed
automatically.
If a measurement in a sequence has already been made, it may
be skipped. The system will invoke the next measurement in
the sequence.
Pressing the top of the Ellipse rocker switch skips a
measurement in the sequence.
Pressing the bottom of the Ellipse rocker switch moves back to
measurements previously skipped.
Press the Clear key to quit a sequence at any time. The final
calculation result can not be obtained.

Advanced Cardiac Calculations
Re-measurement
Overview
Values obtained during Advanced Cardiac calculations or after
a calculation sequence has been completed can be
re-measured as long as those measurement results remain
displayed on the screen.
However, once the measured values are deleted from the
display by the CLEAR function or by scrolling off the top of the
measurement display area, re-measurement is not possible.
Operation Method
1. Complete the calculation or calculation sequence.
2. Measurements and resultant calculations will be
displayed in the designation area. Only those
measurements displayed are available for
re-measurement.
3. Press the Measurement key and the top of the Ellipse
rocker switch. The first measurement available to be
re-measured will be highlighted and the name is
duplicated at the bottom of the measurement display
area.
4–38
4. Use the Ellipse rocker switch to select the desired
value to re-measure.
Calculations and generic measurements are not
available to be re-measured and will be skipped in the
selection process.
NOTE: The re-measurement function is not available with the
Single Plane DISC and Bi-Plane DISC methods.

selected value using the Trackball and Set key.
When the Set key is pressed to complete the
re-measurement:
The resultant value of the selected item and all
related calculations will be recalculated and
displayed on the screen.
The new result will be entered on the report page.
The old measurement is deleted from the screen
and report page as it is replaced by the new value.
Hints
Each value of an M-Mode continuous sequence can be
remeasured separately.
If a measurement is selected from the soft-menu during the
re-measure process, the re-measurement process is cancelled
and the old value is restored.
After a re-measurement is complete (fixed), the old graphic is
erased and the same cursor symbols are used for the
remeasured value.
If two or more identical measurement items are displayed in the
calculation result area, only the last one supports
re-measurement.
The re-measurement of Heart Rate is always manual, even
though Auto Heart Rate is selected as a preset.
There is no automatic compare function for Systole/Diastole.
It is not possible to do re-measurements on VCR playback
values in Image Memory.
Re-measurement is not possible during a calculation sequence.
Only after the sequence is compiled.
Once cleared or erased, measurements cannot be recalled for
re-measurement.

Advanced Cardiac Calculations
Automatic Determination of Systole and Diastole
The system can be programmed to automatically determine the
cardiac phase as systole or diastole. The parameter in the
Setup/Preset Program Sub-Menu page 3 used to make this
selection is:
Diastole/Systole Determination : Manual Auto
The auto determination of systole/diastole can be fine tuned
using the following parameters also found in Set Up/Preset
Program page 3:
R Delay Time of End Systole Prior Edge : 0–2000msec
End Systole Period from Prior Edge : 0–2000msec
Automatic
If Auto is selected, the determination is made by comparing the
displayed B-Mode or M/D Mode image frames with the R-point
on the ECG wave. Therefore, ‘s’ for systole and ‘d’ for diastole
is added automatically to the measurement or calculation name.
If phase cannot automatically be determined, the system
displays the following message:
“Diastole (‘d’) or Systole (‘s’) ?”
Entering ‘d’ or ‘s’ are the only two acceptable inputs.
‘s’ Erases the message, recognizes the
phase as systole and adds a ‘s’ to the end
of the measurements or calculations.
‘d’ Erases the message, recognizes the
phase as diastole and adds a ‘d’ to the end
of the measurements or calculations.
The user will not be able to perform measurements of the
opposite phase until the next image change is made.

Advanced Cardiac Calculations
When the measurement phase requested by the system is
different than the phase of the cursor position, the following
message is displayed:
“Display ######### image”
######### represents the phase opposite of the one just
completed.
Auto determination of systole/diastole is only available on a
frozen image. It cannot be done on a recalled image or one
from an external video input.
If Manual is selected, each measurement has a ‘s’ or ‘d’ at the
end of it’s name. The system will not determine the phase or
ask the operator to make that determination.
Auto Trace Measurements
Doppler measurement menus (D-AV, D-MV, D-PV and D-TV)
each have a selection called Auto Trace. When the user
selects Auto Trace, the start point and end point of a
measurement is set. After the end point is set, the system
traces the waveform and automatically calculates the values as
follows:
Ao Auto Trace: (Set start and end points for FVI-AV)
Calculates: FVI-AV, MaxPG, MeanPG, Ejection Time, AccT,
MV Auto Trace: (Set start and end points for FVI)
Calculates: FVI, MaxPG, MeanPG, Pressure Half Time, MV

Continuous M-Mode Measurements
When M-Mode measurements can be taken on the same
timeline, the system will support a continuous measurement of
all values along that line.
This can be done because the end point of one measurement is
the start point of the next measurement. After the end point of
the last measurement is set, keystrokes are reduced by not
having to set the next start point.

After selecting the measurement sequence, use the Trackball
to position the first cursor and press Set. The name of the first
value appears; use the Trackball to position the cursor at the
end of the first measurement and press Set. This is the start
point of the next measurement. The name of the next
measurement appears; use the Trackball to position the end
point of the second measurement and press Set.
This process continues until all measurements are taken.

Hints
The Ellipse rocker switch is used to skip measurements or
move back to measurements that were skipped.
Before the end point is set, uncompleted measurements can be
removed by pressing Clear once. That measurement can then
be started again.
Measurements can be taken in Zoom mode as long as the
magnification is not changed during the measurement process.
Measurements can be programmed not to appear in the
continuous measurement sequence in the Set Up/Preset
Program menu pages 5 and 6.
If the measurement is set to OFF in the Preset Program menus,
it will not appear in the continuous sequence. Additional Set
points will have to be made if measurements are skipped in the
continuous sequence.
Advanced Cardiac Calculations Measurement Menus
The illustrations that follow show the Advanced Cardiac
Calculation measurement Sub-Menus that are available with
the AMCAL option.
Each selection in the first layer of Sub-Menus will yield a
second layer of Sub-Menus. This second layer contains
measurements and calculations necessary to complete the
category or goal selected in the first layer.
The illustrations shown are those that result if the determination
of systole/diastole is set to Automatic and then Manual.
