This general Template provides detailed information on projection X-Ray dose value accumulations over several irradiation events from the same equipment (typically a study or a performed procedure step).
Table TID 10002. Accumulated X-Ray Dose
DTID 10004 “Accumulated Fluoroscopy and Acquisition Projection X-Ray Dose” |
IFF TID 10001 Row 4 = (113957, DCM, "Fluoroscopy-Guided Projection Radiography System") or TID 10001 Row 2 = (113704, DCM, "Projection X-Ray") and TID 10001 Row 4 is absent) |
|||||||
IFF TID 10001 Row 2 = (71651007, SCT, "Mammography") |
||||||||
IFF TID 10001 Row 4 = (113958, DCM, "Integrated Projection Radiography System") or TID (10001) Row 4 = (113957, DCM, "Fluoroscopy-Guided Projection Radiography System") or TID (10001) Row 2 = (113704, DCM, "Projection X-Ray") and TID (10001) Row 4 is absent) |
||||||||
DTID 10006 “Accumulated Cassette-based Projection Radiography Dose” |
IFF TID 10001 Row 4 = (113959, DCM, "Cassette-based Projection Radiography System") |
|||||||
Required if the irradiating device is not the recording device and the dose was accumulated on a single device. |
$DeviceProcedureRole = EV (113859, DCM, "Irradiating Device") |
|||||||
EV (128756, DCM, "Equipment Landmark to Patient Fiducial Z Distance") |
Date that the calibration of the equipment's dose indicators was performed |
|
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. |
|
Value range from 0 to 100 percent. Uncertainty of the 'actual' value expressed as+/- of the mean. |
|
Identifies Individual or organization responsible for calibration |
|
Describes calibration protocol according to equipment standards or local guidelines. |
|
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. |
|
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. |
|
In many instances, the values will be either:
|
|
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. |
