In the Image Processing Parameter Window can Image Processing parameters be tuned
by the CSE. By pressing reset, par ameter s will be set to a validated set of parameters. To
be able to modify image processing the different parameters has to be explained.

DIGISCAN M will use an image processing softw are MFP (Multi- Objectiv e Frequency Pro­cessing) from Fuji Photo Film Co., Ltd.

The controlling parameters can be divided in three groups:

• Gradation Processing

• Multi-Objective Frequency Processing (MFP)

• Dynamic Range Control (DRC)

Gradation Processing 6

Gradation processing is performed to convert the digital input data to an image with
appropriate density and contrast.

The gradation process is controlled by the following four parameters:

• GT (gradation type)

A curve providing gradation. Two curves for Mammography are provided.

• GA (rotation amount)

Parameter for varying the contrast.

γ = γ(GT) x GA Th e γ v alue det ermined by GT is multi plied b y GA to obtain the

final

γ value.

• GC (rotation center)

Density center for rotation. The density at the rotation center remains
unchanged even when the GA changes.

• GS (density shift)

Paramete r for c hangi ng the density. Density change amount when GA = 1.0 f or
linear gradation.

Gradation process adjustment procedure 6

Most adjustment can be made by v arying the GA and GS parameters . If such adjus tments
do not help, you should reassess the GT parameter. (There is no need to vary the GC
parameter.)

First, vary the GS param eter so as to obtain the proper density
Next vary the GA parameter so as to obtain the proper contrast.
If, for instance, GA = 1.2 the resulting contrast is 1.2 times higher then exhibited when

GA = 1.0.

Multi-Objective Frequency Processing (MFP) 6

Overview 6

The multi-objectiv e frequen cy process (hereinaf ter referre d to as the MFP) w as de v eloped
intended to improve the diagnostic image quality provided by image proce ssing. This new
process depicts gray-scale shadows and shape shadows while providing natural appear­ing enhancements and offering a wide visibility range suitable to the diagnostic purpose.
Moreover, this process makes well-balanced enhancements to all spatial frequency com­ponents and suppresses ov ershoots that might be caused by strong signals. Further con­siderations are also given to this process to avoid unnaturalness.

Radiograph features 6

The MFP can make well-balanced enhancements to various structures, from large to
small ones. When used in conjunction with a gr adation process, the MFP also offers the
following features:

1. Gray-scale shadows and shape shadows can be enhanced in a wel l-balanced
manner without sacrificing the grai niness.

2. Invisible areas can be depicted with an i ncreased degree of naturalness.

3. The degree of enhancement is suppressed for meta ls and other structures
extraneous to the human body.

Principles 6

1. Process overview

The MFP has two functions: frequency enhancement f or enh ancing dot and line shadows
and DRC for controlling the image dynamic range . In the basic MFP, smoothed images
are first generated, after which the difference between each smoothed image is deter­mined. The resulting difference-images are subjected to nonlinear conversion, and then
the sum of the converted difference-images is used to perform frequency enhancement
and DRC processes.

2. Smoothing Process and subtraction pr ocess

In the MFP's smoothing process, because wei ghting is conducted prior to smoothing, the
resulting smoothed images are more natural than tho se derived from simple averaging.
(See Fig. 4.) The frequency response shown in Fig. 5 indi cates that the response charac­teristic is smooth.

Siemens-Elema AB Register 5 SPB7-420.816.01 Page 5 of 12 DIGISCAN M
Solna, Sweden Rev. 04 02.03 SPS-UD System Manual

6 - 6 Image Processing

The signal differentials between neighboring smoot hed image signals have a response
characteristic shown in Fig. 6, representing a so-called band pass signal consisting of
specific frequency components.

Fig. 4

Fig. 5 Smoothing signal response Fig. 6 Response of signal differentials between neighboring

smoothing signals.

3. Enhancement signal components

All band pass signals (signal differentials
between smoothed signals) are subjected to
nonlinear conversion, which is detailed later.
Further, they are added with their sizes
adjusted to create basic enhancement signal
components. A typical example is shown in
Fig. 7.

The enhancement frequency response can
be controlled as desired for enhancement
signal components.

Unlike the conv e ntional frequency pr ocess, a
smooth response characteristic is obtained,

Fig. 7 Spatial frequency (cycles/mm)

minimizing the degree of unnaturalness
inherent in processing.

System Manual Rev. 04 02.03 SPS-UD Solna, Sweden

Image Processing 6 - 7

4. Contrast-dependent nonlinear function conversion

If an image containing a metal or other strong signals is enhanced by the conventional
process, artifacts may be generated around the si gnal. The MFP suppresses such strong
signals, provi ding the enhanced image a natural look. With reference to Fig. 8, i f, for
instance, a band pass signal (d iffer ence-i mage sign al) having a relatively low contrast (as
indicated by (1) in th e figure) is entered in relation to the indicated nonlinear function, the
resulting output signal (1)' has the same contrast as the input signal. However, if a high­contrast signal is entered (as indicated by (2), it is converted to generate an output signal
having a lower contrast (2)' ).

When the nonlinear function is used in the frequency enhancement process, the very
small signals with low contrast are enhanced normally while the degree of enhancement
is suppressed for metal portions and other high-contrast edges.

5. Actual enhancement characteristic

The MFP's frequency enhancement function of fers various parameters that enable you to
freely control enhancement frequency characteristics. A typical response function for nor­mal expression is shown in Fig. 7. In actuality, the response characteristic has the fre­quency response and contrast char acteristic variables shown in Fig. 10. While these let
you adjust various frequency components and the degree of contrast dependence,
sophisticated knowledge of adjustments is also required.

To avoid this expertise issue, various parameters are predefined for implementing stan ­dard frequency responses so that you can perf o rm frequency enhancement processes
having various frequency responses simply by choosing a frequency balance type.

The DIGISCAN M system has two different response characteristics, or balance type
parameters. To facilitate the comparison of the frequency responses, Fig. 10 shows the

frequency responses in the low-contrast region when the degree of enhancement (MRE)

is 1.0.

Fig. 10

DRC process based on edge-retention smoothing signal components 6

The conventi onal DRC process obtains smoothed images by simple a veraging. The
images smoothed by the MFP's DRC process retain edges; when the contr ast is high, the
high-frequency response is retained.

Fig. 11 is used to explain why such a complicated process is performed.
Images having unsmoothed high-contrast edges (referred to as edge-retai ning smoothed

images) are used for the MFP's DRC function that smoothes low-contrast signals, which
enables adequate DRC near edges to depict in vi sible areas in a relatively natural manner
(G).

Image Processing 6 - 9

On the basis of the edge-retaining smoothed image characteristic determined by the
MFP's DRC balance type (MDB), the optimum DRC process is implemented by the multi­DRC enhancing type (MDT) and MFP's degree of multi-DRC enhancement (MDE).

Fig. 11

Parameter overview 6

The MFP includes the following six types of parameters: Three types that control the fr e­quency enhancement and the other three types that control the DRC.

Paramet ers that control frequency enhancement:

• Multi-frequency balance type (MRB)

• Multi-frequency enhancing type (MRT)

• Degree of multi-frequency enhancement (MRE)

Paramet ers that control the DRC:

• Multi-DRC balance type (MDB)

• Multi-DRC enhancing type (MDT)

• Degree of multi-DRC enhancement (MDE)

Multi-frequency balance type (MRB)

This type of parameter represents frequency characteristics of enhanced images. One
balance type, G, are available. Type G mainly enhances higher frequencies.

Multi-frequency enhancing type (MRT)

The parameter MRT is a tab l e that uses i mage signal di git al values (virtually proportional
to density) to determine the degree of enhancement v arious ly for al l densi ties. T w o tab l es
P and R are provided. P is recommended.

6 - 10 Image Processing

Degree of multi-frequency enhancement (MRE)

Before determining the degree of frequency enhancement, it is necessary to determine
the degree of difference image (the edge extraction image) additi on the degree of such
addition is determined by the parameter MRT. However, if the enhancement is provided
indiscriminately the resulting image will appear coarse because of the tendency of low­density portion to be noisy. Value ra nges from 0.0 to 1.6.

Multy-DRC balance type (MDB)

This parameter represents freque ncy characteristics of smoothed images. One type E is
provided.

Multy-DRC enhancing type (MDT)

This parameters determines the density range over which DRC is to be exercised. Two
parameter value E or F is provided for high density control.

Degree of multy-DRC enhancement (MDE)

This parameter determines the degree of control. An excessively high setting will cause
white/black image reversal, fog significantly the image of a low-density area, or lower the
highest density of a high-density controlled area. Parameter can be set from 0 to 1.0. A
setting of 0.6 or low er should normally be used.

Pattern Enhancement Processing for Mammography (PEM) 6

NOTE

Considering that fine calcif ica tion i mages are li kely to be less visible on the digiti z ed mam­mography image, we have invented and developed, based on the image recognition tech­nology, image processing that extracts and enhances locations that look like calcification
images.

This image processing is employed exclusiv ely f or mammog raphy images. Extraction and
enhancement of the location assumed to be calcified on the mammography image will
make processing possible to handle such image without deteriorating granularity on the
whole image. If this image processi ng is combined with Multi-objective Frequency Pro­cessing (MFP) and/or conventional frequency processing, the following features will be
provided.

1. Well-balanced images can be obtained by separ ately controlling enhancement of
tumor shadows and calcification images, without deteriorating the image
granularity.

2. Oversights in breast examinations can be av oided by enhancing signals that are
suspicious of calcification images .

PEM Enhancement Coefficient (PRE)

PRE is a parameter of the same definit ion as that o f RE of the con v enti onal frequency pro­cessing. PRE defines the degree of enhancement of a calcification image and values
range from 0.0 to 9.9 and 10 to 16.

PEM Enhancement Ranking (PRN)

PRN is a parameter of the same definition as that of RN of the conventional frequency
processing. For the paramet er range , mask si zes are d efined from A to E. Table 7.1 shows
the relationship betw een PRN and the equ iv alent frequency band on the IP. Mask sizes for
PRN have been defined based on the fr equency bands listed in this table.

PEM Edge Information Detection Level (PTE)

PTE is a parameter that defines the edge i nformation detection level for PEM. Using PTE,
edge information detection signals are conv erted to the edge information detection l e v els.
For the parameter range, edge information detection levels are defined from A to J.

Fig. 12 shows definitions of l e v el A to J of PTE. The detecti on le v els ha v e been set to shi ft
to the right one by one as the alphabet goes from A to J.Thus, the lowest edge detection
level is J.

In addition, because the edge detection level depends on both the noise level (S value)
and the contrast (L value) of the target image, PTE is corrected based on the PTE level
selected according to para meters mentioned above, depending on the S and L values for
each image.

PEM Calcification Image Table (PTC)

PTC is a parameter that defines the calcification image detection level for PEM. Using
PTC, calcific ation image position dete ction signals are con verted to the calcification image

are defined from A to J. Fig. 13 shows. defini tions of le vel A to J of PTC. Same as for PTE,
the detection levels have been set to shift to the right one by one as the alphabet goes
from A to J. Thus, the lowest calcification image detection level is J.

In addition, because the calcificat ion image detection level depends on both the noise
lev e l (S value) and the contrast (L value) of the target image, PTC is corrected based on
the PTC level selected according to parameters mentioned above, depending on the S
and L values for each image .
