Collimate for exam
Note:
Auto Image Paste registration can cause narrowing of the field. Do not collimate too tightly,
because the outer 1-2 cm may be collimated in the pasted image.
17. Press the [SET] button (
) on the OTS control screen when finished.

[SET] button
Note:
The wallstand receptor, tube, or both may move. Warn the patient to hold still.
If the area is not within the acceptable range for the protocol, the [HEAD], [FOOT], and [SET] buttons
become disabled and a message appears in the status area. Press [RESET] and start over.
Once you press [SET], the lateral and vertical collimation knobs on the OTS are locked out. That is,
turning the knobs will not change the collimation.
Once you press [SET], if you change the SID or Tube angle, you will need to re-press the [SET] button
before acquisition is allowed.
Moving the tube out of lateral detent will inhibit exposures until the tube is re-positioned.
Press the OTS control screen (
) or the Emergency Stop button on the RCIM to stop the
tube movement.

18. Make exposure using the hand switch.
Hold the exposure button down until all exposures have been made. The Image Count area under
the SID and Grid information counts down each image as it is exposed (
). Releasing the
switch early will terminate Auto Image Paste processing. Any acquired images will still be able to be
manually pasted. Refer to
for more information.
If exposure stopped because of early hand switch release or if you want to retake the exposure with
the same COI, head, and foot settings, press the [SET] button on the OTS control screen to reset the
tube to its initial position and use the hand switch to make the exposure.
