Rev 1.1 VisualSonics Vevo 2100 Imaging System Operator Manual 193
Chapter 33: Acquiring B-Mode images
Area Description
Focal depth indicator. When you acquire data, use the Focal Zones control on the control
panel to add up to three focal zones.
Transducer orientation indicator. The line in this icon corresponds to the orientation
ridge on the transducer and indicates the orientation of the probe relative to the image.
Dynamic range bar. Indicates the input signal strength that is mapped into the gray scale
of the display. When you acquire data, use the Dynamic Range control on the control
panel to change the range.
Physiological data trace window. Displays your animal's heart rate, temperature,
respiration rate and blood pressure data. During data acquisition this information comes
from the Advanced Physiological Monitoring Unit connected to the Vevo Imaging Station.
During an image review you can add time and ECG amplitude measurements in this
window.
Live physiological data values. Displays the recorded numeric values of the animal's
heart rate, respiration rate, blood pressure and body temperature.
Cine loop range control. Displays the length of the cine loop range. The triangular white
marker identifies the individual frame number within the cine loop. You can drag the left
and right vertical markers to display only the image frames in that range.
Live physiological display. If the animal is connected to the physiology controller, data
appears here in real time during image acquisition and can display the numeric values of
the animal's heart rate, respiration rate, blood pressure and body temperature. This area
also displays the image data storage capacity progress bar so you can see when you
should start to back up your image data to free up space on the system. Live physiological
data is only active when you enable the inputs in the General tab of the Preferences
window.
Screen keys display
Displays the updated parameter and system information when you make adjustments

to set the panel to display the Mode settings. This is the default panel when you open a Mode
window.
Press
Measure
to set the panel to display the measurement tools. These tools are not available when you are
acquiring or reviewing images.
Press
Physio Settings
to set the panel to display the options for a) viewing and manipulating physiological data
input from the Advanced Physiological Monitoring Unit and b) manipulating the Respiration Gating and ECG Trigger
controls.
For complete information on how each panel works, see Left panel workspace (page 47).
