6.2 Image Magnification
NOTE: Zooming an image changes the frame rate which tends to change the thermal indices.
The position of the focal zones may also change, which may cause the peak intensity to
occur at a different location in the acoustic field. As a result, the MI may change.
6.2.1 Spot zoom
To use the function, use the knob on the control panel.
1. Press <Zoom> to enter the sample volume definition status.
2. Roll the trackball to change the box size and position. Press <Set> to toggle between setting the
size and position, or rotate the <Zoom> knob to adjust the size. After the sample volume is set,
press the <Zoom> key again to enter spot zoom status.
3. Rotate the <Zoom> knob or to change the magnification factor. Or enter the touch screen
mapping mode, and zoom the image by pinching two fingers on the touch screen. The image
magnification factor value will display in real time in the image parameter area. For example,
indicates that the magnification factor is 1.3.
