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​

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") [1354] = (88986008, SCT, "Vertex of Head") with EV (128773, DCM,​

 

"Reference Geometry") [1354] = (128120, DCM, "Plane through Superior Extent") [1338], or​

 

•​EV(128772,DCM,"ReferenceBasis")[1354]=(56459004,SCT,"Foot")withEV(128773,DCM,"Reference​

 

Geometry") [1354] = (128121, DCM, "Plane through Inferior Extent") [1338]​

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.​

TID 10003 Irradiation Event X-Ray Data​

This Template conveys the dose and equipment parameters of a single irradiation event.​

The Template and requirements are structured to consider equipment with various levels of integration between the components (X-​ Ray Source, Plate or Detector, and Gantry/Table) of the equipment.​

An irradiation event is the loading of X-Ray equipment caused by a single continuous actuation of the equipment's irradiation switch,​ from the start of the loading time of the first pulse until the loading time trailing edge of the final pulse. The irradiation event is the​ "smallest" information entity to be recorded in the realm of Radiation Dose reporting. Individual Irradiation Events are described by a​ set of accompanying physical parameters that are sufficient to understand the "quality" of irradiation that is being applied. This set of​ parameters may be different for the various types of equipment that are able to create irradiation events. Any automatic on-off​ switchingoftheirradiationsourceduringtheeventshallnotbetreatedasseparateevents,rathertheeventincludesthetimebetween​ start and stop of irradiation as triggered by the user. E.g., a pulsed fluoro X-Ray acquisition shall be treated as a single irradiation​ event.​

As described in Section 6.2.4, measurement concepts may be post-coordinated, even though not explicitly specified in the Template.​ In particular, post-coordination using modifier concept (121401, DCM, "Derivation"), with modifier values drawn from CID 10009​ “Measured/Calculated” would be appropriate to encode indications of measured or of calculated values.​
