2.4.2. Exposure
After the patient is properly positioned in the machine, momentarily pressing either the
Return button or Exposure switch again sends the Rotation unit to the Ready position.
The READY indicator illuminates when the unit has reached the Ready position.
A.
To start exposing an image: Press the Exposure switch to initiate the exposure and
keep the switch depressed during the entire travel of the Rotation unit. The yellow X-
ray warning light on the Exposure switch will illuminate and an audible alarm will
sound as X-rays are emitted.
B.
To stop an exposure immediately at any time: Release the Exposure switch, which
terminates the exposure immediately. Interrupting an exposure illuminates the Error
indicator and sounds an alarm. Pressing either the Return button or the Exposure
switch extinguishes the Error indicator and silences the alarm. Pressing either button
a second time moves the Rotation unit to the Patient Exit / Entry position.
2.4.3. Monitoring During Exposure
During the exposure, the Control System monitors movement of the Rotation unit and X-
ray generation according to the selected projection.
2.4.4. Reset for Next Exposure
After the exposure the Rotation unit comes to rest at the End of Exposure position.
Momentarily pressing either the Return button or Exposure switch at this time sends the
Rotation unit to the Patient Exit position.
