2-1 Zoom
When the image is first displayed in the viewing area, it is displayed with a Zoom factor called "Fit to
Screen". The Zoom factor is calculated so that all of the image is displayed in the space available in the
viewing area.
• Click on the appropriate Zoom button to select the desired Zoom factor:
Zoom=1 corresponds to a full resolution display: each pixel on the screen corresponds to a pixel on
the Digital Detector.
Zoom=1/2 corresponds to a half resolution display: a pixel on the screen corresponds to the average
of 4 pixels on the Digital Detector.
Fit to Screen: the image is displayed at a Zoom factor that optimizes the screen layout.
True Size: the image on the screen is displayed with the same size as that of the original breast
image projected onto the Digital Detector. This facility is not available when viewing SCPT images.
