Three buttons are located beneath the Capture button. When FastTrac is turned on, the
button on the left is green
. Clicking this button toggles FastTrac on and off for the
current scan. The button turns gray when tracking is off.
Clicking the button in the middle
provides information on how to ensure the scan can
be performed with FastTrac.
The button on the right is the Track to Prior toggle button. When a previous scan is
available, the button is green
. If the user does not wish to track to a prior scan, this
function can be turned off by clicking this button, which will turn from green to gray.
1. Follow the same alignment steps as for a non–tracked scan.
2. Ensure the B-scans are centered. Click the up and down arrows or use the mouse
scroll wheel to make fine adjustments to center the scan. Clicking the Optimize or
Center buttons automatically adjusts the vertical position of the B-scans.
NOTE: For optic disc scans, the Capture button may still be green if the scan is not
completely centered.
3. Maximize fundus image quality. FastTrac is most robust and efficient when the fundus
quality is high. Fundus quality is also important for ensuring accurate and successful
tracking to the same location in subsequent scans. High quality fundus images are
well focused with sharply delineated blood vessels and have uniform illumination
without dark corners.
