Content Item Descriptions

Row 5 | Date that the calibration of the equipment's dose indicators was performed
Row 6 | Typically a value provided by the medical physicist. The recorded dose or dose area product values in this report can be multiplied by this factor to obtain estimated real-world values. ### Note It is important that this value must not be applied to the measured values before storing them in the report.
Row 7 | Value range from 0 to 100 percent. Uncertainty of the 'actual' value expressed as+/- of the mean.
Row 8 | Identifies Individual or organization responsible for calibration
Row 9 | Describes calibration protocol according to equipment standards or local guidelines.
Row 14 | The device that produced the irradiation accumulated in this Template. I.e., the X-Ray source. This is not required to be present if the information is the same as that already recorded in TID 1004 “Device Observer Identifying Attributes” encoded via the inclusion of TID 1002 “Observer Context” in TID 10001 “Projection X-Ray Radiation Dose” Row 5, which in turn may be absent if identical to the content in the Enhanced General Equipment Module, or if more than one device produced the accumulated irradiation.
Rows 16 and 17 | These coordinates relate a visible landmark on the X-Ray table to the Table Reference Point that is arbitrarily defined by the manufacturer and not necessarily visible to the operator. The Equipment Landmark Y Position is not recorded since it is, by definition, in the plane of the table as is the origin of the Table Coordinate System so the value would always be zero.
Row 19 | In many instances, the values will be either: EV (128772, DCM, "Reference Basis") = (T-D1120, SRT, "Vertex of Head") with EV (128773, DCM, "Reference Geometry") = (128120, DCM, "Plane through Superior Extent"), or EV (128772, DCM, "Reference Basis") = (T-D9700, SRT, "Foot") with EV (128773, DCM, "Reference Geometry") = (128121, DCM, "Plane through Inferior Extent")
Row 20 | This distance (likely recorded by the operator) locates the patient with respect to an X-Ray table landmark. The patient is assumed to be centered in the left-right axis of the X-Ray table.
