Figure 10-13 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 10-13 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 in front of the wallstand.
Note: When in AEC mode, the body part must cover the selected ion chambers in order to achieve the
proper exposure.
Note: Some facilities may be equipped with a 4-cell ion chamber wallstand. Refer to Chapter 8: System
Hardware Overview-Ion Chambers (p. 8-42) for more information about how this affects ion
chamber selection and patient positioning when used horizontally with a mobile table accessory.
Note: When lift up or down the wallstand housing, lateral bar need to rotate to its park position to avoid
lateral bar hitting on patient or operator body.
8. Confirm or adjust the Patient Side field, if applicable.
9. Confirm or adjust the Patient Position field.
10. Confirm or adjust the Asymmetric Collimation, if applicable.
11. 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.
12. Have the patient suspend respiration, if required.
13. Make exposure using the hand-switch.
