 Radio Button Cluster: There is no restriction on moving a single radio button. However,
we suggest that they are grouped adjacent to each other. When they are grouped in this
way the system will automatically draw a border around them to indicate they are a
related group of radio buttons.
 TGC: The TGC is a special control that cannot be moved. It is always on the right side of
the B-mode tab.
For most tabs, there is one arrangement for the controls and the customized arrangement will be
remembered across exams and system power-ups. However, the following tabs can have
customized arrangements for different exam types:
 Comments
 Body Markers
 Measurements
These functions are often configured differently for different exams. For example, the
measurements for an OB exam are different from those of an abdomen exam. Each configuration
of these tabs is stored in an application preset (see Chapter 8 Presets, for details)

3.9 Trackpad

In general, the system trackpad is used like a trackball or similar pointing device, used on most
ultrasound systems. Using a trackpad instead of a trackball helps makes the system easier to clean
as the area around the trackpad is completely sealed. In addition, the trackpad supports several
other functions that would not be possible with a traditional trackball:
 The trackpad supports multi-finger gestures. For example:
o While in B-mode a pinch-out gesture can be used to zoom the image.
o While in Color a pinch gesture can re-size the ROI.
 Dragging along the Swipe button at the top of the trackpad as a primary sliding control.
For example:
o In most live imaging modes, this adjusts the Overall Gain.
 The top right of the trackpad is reserved as a 'Set' button. Pressing 'Set' is generally
equivalent to a single click on a mouse or trackball. For example:
o In CD, it is used to toggle between controlling the size and the position of the pan
box.
o In Measure, it is used to toggle between controlling of the individual calipers when
using a caliper pair.
 The top left of the trackpad is reserved as an 'Enter' button. Pressing 'Enter' is generally
equivalent to a double click on a mouse. For example:
o In Measure, it is used to enter a measurement into a report.
The examples provided above are a subset of how the trackpad is used. Additional examples are
provided in specific feature descriptions elsewhere in this manual.
