CAUTION It is critical to select the proper patient size on the Acquisition screen. The incor-
rect Patient Size may result in an unnecessarily large radiation dose or multiple
exposures.
3. Select the Table Receptor, if necessary (Figure 10-10).
Figure 10-10 Receptors: Table receptor selected
4. Select [AEC] or [FIXED] mode (if applicable for the protocol).
5. Confirm or adjust the Grid and SID status.
Figure 10-11 Grid and SID status
ï‚· An alert icon appears if the current Grid or SID is not in the recommended status for the technique.
ï‚· A checkmark appears if the current Grid or SID is in the recommended status for the technique.
ï‚· Figure 10-11 shows the Grid not in the recommended status and the SID in the recommended sta-
tus.
Note: You may still be able to take exposures even if the grid or SID are not in the recommended status.
6. Make technique adjustments as necessary: kV, mA, Focal spot, Cu Filter, and Ion chambers (AEC
mode only).
Note: Click [RESET TECHNIQUE] at any time to reset the technique to the default protocol settings.
7. Position the patient on the table.
Note: When in AEC mode, the body part must cover the selected ion chambers in order to achieve the
proper exposure.
8. Confirm or adjust the Patient Side field, if applicable.
9. Confirm or adjust the Patient Position field.
10. Collimate and shield as appropriate for the exam.
CAUTION If using AEC mode, collimation must be active over the ion chambers being used. If
it is not possible to collimate over the selected ion chambers, then FIXED mode
must be used in order to prevent possible patient over-exposure.
