A2 2D-Mode and M-Mode Imaging Functions
Ensemble Tissue Harmonic Imaging
Ensemble™ Tissue Harmonic Imaging (THI) is a system feature that can
enhance contrast resolution with fine tissue differentiation, benefiting
difficult-to-image patients.
THI creates 2D-mode images from the received signals using the harmonics
of the transmitted (fundamental) frequency. Harmonics are multiples of the
fundamental frequency. The system utilizes the harmonics produced in
tissue by the non-linear propagation of an ultrasound wave. A pulse
sequence technique is used to remove the fundamental signals without
affecting the harmonic signals. The harmonic signals have a narrower main
lobe and lower side lobes than fundamental 2D-mode signals, resulting in
improved spatial and contrast resolution.
To activate THI:
1. Push up on the MULTIHERTZ control until a "T" displays next to the
transmit frequency in the upper left of the image area.
2. To exit THI, push down on the MULTIHERTZ control until the
"T" is removed from the screen.

A2 2D-Mode and M-Mode Imaging Functions
Optimizing Contrast Resolution and Brightness Uniformity (TGO)
The TGO™ Tissue Grayscale Optimization technology optional feature
optimizes the image's contrast resolution and brightness uniformity by
shifting low-level amplitude signals to the grayscale range optimal for
viewing.
When you activate TGO, the system immediately optimizes the image's
contrast resolution and brightness uniformity and displays the
"TGO" symbol below the active image indicator to indicate that TGO is
active. TGO remains active for the current examination until you exit TGO,
end the current examination, or select another exam type or transducer.
For software versions 2.0 and higher: You can also select an offset
(TGO gain) for preferred image brightness with TGO during the current
examination (for the current exam type and transducer). The selected value
represents the increments of gain adjustment to be added to or subtracted
from the default optimized gain.
If you activate a 2D-mode imaging feature that supports TGO (such as THI),
then the system automatically updates the optimization for that imaging
feature. When you exit TGO, the system removes any gain adjustments you
made while TGO was active and removes the "TGO" symbol from the
screen to indicate that TGO is no longer active.
You can configure the following documentation controls for TGO activation:
DIGITAL STORE 1
DIGITAL STORE 2
To activate TGO, choose one of the following methods:
During 2D-mode imaging, press the documentation control
(DIGITAL STORE 1 or DIGITAL STORE 2) configured for TGO

The CINE function is available in all imaging modes except 4B-mode. During
real-time imaging, the system places the most recently acquired images as
well as the image currently on screen into a CINE memory buffer. You can
view images stored in CINE memory using a review method.
Frame Review – The Frame function is the system default. Use the
trackball to cycle through the frames of data, one at a time, either
forward or backward. You can also use the Frame function to select
individual frames for printing or for storing on a disk.
Motion Review – The Motion function provides a continuous display
of stored data, in the forward direction only. Data can be played back at
the same frame rate at which the data was acquired, or the playback
speed can be adjusted. All of the available frames can be viewed, or
a segment can be selected using the Edit Start and Edit End options.

Measurement Function Overview
The measurement function contains the measurements and calculations
available for each exam type and imaging mode. You can use the
measurement function during a patient examination, on images stored in
CINE Review.
General and Exam-Specific Measurements
The ultrasound system contains measurements and calculations that are
either
General
– standard for all exam types – or
Exam-specific
– particular
to one exam type.
Calculations use formulas that require specific measurements. The system
automatically performs a calculation when the required measurements have
been completed.
Measurement Setup
Use the system presets to customize the Measurement function.
Specify the shape, size, and default position for the caliper.
Activate or deactivate a background for the Measured Results section of
the image screen.
