Write Zoom
Zooming an image changes the frame rate which tends to
change 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 (TI)
may change.
NOTE: Write Zoom is available only when CrossXBeam is off.
To activate Write Zoom, press the Zoom knob.
With Write Zoom, the Ultrasound line density and/or sampling
frequency increases, giving a better resolution.
Available only in pre-processing.
You can preset the write zoom window size (height and width)
on Utility -> Imaging -> B-Mode.
NOTE: The difference between Read Zoom and Write Zoom can be
described in relation to photography. With a photograph, Read
Zoom manipulates the negative and enlarges the picture;
whereas Write Zoom uses a telephoto lens to bring the image
closer before taking the picture.
Observe the output display for possible effects.
First use the Read Zoom (turn knob) to get to the area of
interest, then use Write Zoom (press knob).
