Chapter 35: Acquiring M-Mode images

Area Description

Sample gate overlay in B-Mode scout window. Shows you precisely where the region of

interest is. The region of interest is located between the yellow wireframe brackets set. Use

this window to reposition your transducer and the wireframe brackets set so you can

acquire the most useful data.

M-Mode image data. Displays the cardiac cross-section image data acquired along the

sample gate line in the B-Mode scout window. When you review an image, this is the

workspace where you use the image measurement tools to apply your measurements.

Image scale. Indicates in mm the distance from the face of the transducer.

Region of interest image window. Displays the sample gate image data that is defined in

the B-Mode scout window above. The most current data begins at the right side of the

window. The trailing data in the cine loop acquisition buffer extends to the left.

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.

Cine loop time scale. In milliseconds. Use the

Sweep Speed

rocker switch to adjust the

range of the scale so you can place more or less cine loop data into the window.

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

on the control panel.

 Displays control options in the mode that you apply during image acquisition when

you press the

Screen Keys

dial. When you display the B-Mode image with the M-Mode

overlay, press to place a needle guide within the image.

Left panel. Displays a unique set of controls and information sections depending on the control key you press:

 Press

Mode Settings

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).
