Patient Preparation
5-13
You will begin to see an image once the patient is positioned in the chinrest. The image
may be poorly resolved until properly focused (see
"Acquiring Scans" on page 6-1 ).
Alignment progresses through a series of steps, although the order in which many of the
steps are performed (and whether they are repeated) will vary depending on the
cooperativeness of the patient (e.g., whether patients can fixate steadily at a requested
location, opacity of their eye, etc.). In general, the sequence of user steps for non–repeat
visits is as follows.
4. If necessary, remind the patient not to press against the head rest too firmly, so the
forehead glides more easily across it during X-Y movements of the chinrest. The video
image of the eye is clearest when the (Z alignment) is correct.
5. Instruct the Patient to relax after capture.
6. After the capture is complete, instruct the subject to relax but maintain chinrest
position while the technician reviews the scan.
7. If necessary, repeat steps 4 through 6 above, until the technician is satisfied with the
scan quality.
8. When the session is complete, instruct the subject to relax and move away from the
chinrest.
NOTE: Clicking the Finished or ID Patient button moves the chinrest into the default or
saved position. Instruct the research subject to move away from the chinrest before clicking
the Finished or ID Patient button.
CIRRUS automatically names the file to include patient name, ID number, gender, type of
scan, date of exam, eye examined, type of report, and date of report.
