| (0018,9172) | Bulk Motion Compensation Technique |
|
Applied technique to reduce bulk or other physiology motion artifacts. Defined Terms: NONE REALTIME = image acquisition shorter than motion cycle GATING = prospective gating TRACKING = prospective through and/or in-plane motion tracking RETROSPECTIVE = retrospective gating CORRECTION = retrospective image correction Required if Image Type (0008,0008) Value 1 is ORIGINAL or MIXED. May be present otherwise. |
| (0018,9173) | Bulk Motion Signal Source |
|
Signal source to measure motion. Defined Terms: JOINT = joint motion detection NAVIGATOR = MR navigator and organ edge detection MR_PHASE = phase (of center k-space line) Required if Image Type (0008,0008) Value 1 is ORIGINAL or MIXED and Bulk Motion Compensation Technique (0018,9172) equals other than NONE. Otherwise may be present if Image Type (0008,0008) Value 1 is DERIVED and Bulk Motion Compensation Technique (0018,9172) equals other than NONE. |
