## X-Ray Radiation Dose SR IOD Templates

The templates that comprise the X-Ray Radiation Dose SR are interconnected as in Figure A-14.

Figure A-14. X-Ray Radiation Dose SR IOD Template Structure

### TID 10001 Projection X-Ray Radiation Dose

This template defines a container (the root) with subsidiary content items, each of which represents a single projection X-Ray irradiation event entry or plane-specific dose accumulations. There is a defined recording observer (the system or person responsible for recording the log, generally the system). A Biplane irradiation event will be recorded as two individual events, one for each plane. Accumulated values will be kept separate for each plane.

Content Item Descriptions

Row 2 | "Projection X-Ray" refers to procedures performed on either integrated equipment (where information is passed between the X-Ray source (generator and tube), detector, and mechanical systems), or non-integrated equipment (where data might not be available for one or more components such as cassette-based systems). The data availability can be described in Rows 8, 9 and 10. The specific type of equipment can be described in Row 4. The coded term for "Mammography" is intended to encompass all types of projection X-Ray imaging of the breast. ### Note Mammography exams are distinguished by a different value in this attribute, Angiography exams are distinguished by the Irradiation Event Type attribute = Fluoroscopy, CR/DR exams are distinguished by one or more of the Data Availability Flags = No, and CT exams are distinguished by the use of a different template.
Row 5 | The observer context may include both a Person Observer identification, as well as the identity of the equipment providing the values for the irradiation event (Device Observer identification), if not inherited.
Row 8 | A value of "No" indicates that details associated with the X-Ray Detector are not available to the device generating this report. For example, an X-Ray Source system might lack any communication with the associated cassette-based X-Ray detector or any method of entering such information. A value of "Yes" or the absence of this row means that the details are available.
Row 9 | A value of "No" indicates that details associated with the X-Ray Source are not available to the device generating this report. For example, a cassette-based X-Ray detector might lack any communication with the associated X-Ray Source or any method of entering such information. A value of "Yes" or the absence of this row means that the details are available.
Row 10 | A value of "No" indicates that details associated with the Gantry and/or Table are not available to the device generating this report. For example, a cassette-based X-Ray detector might lack any communication with the associated gantry/table or any method of entering such information. A value of "Yes" or the absence of this row means that the details are available.
Row 11 | Cassette-based X-Ray systems should consider themselves to be Single Plane systems.
Row 14 | Details of the underlying irradiation events. If Row 18 has a value of "MPPS Content" then a TID 10003 “Irradiation Event X-Ray Data” item may be generated for each item in the MPPS Exposure Dose Sequence (0040,030E), but since this is an optional element in MPPS, if it is absent, empty or incomplete, there may be no irradiation event level information available. Alternatively, the information may be copied or computed from the images.
Row 16 | The Dose Image references a graphic representation of the radiation dose distribution. This may be a Secondary Capture scan of a dosimetry film.
Row 17 | The physician responsible for determining that the irradiating procedure was appropriate for the indications. The value may come from Requesting Physician (0032,1032), Requesting Physician Identification Sequence (0032,1031) or somewhere else based on hospital policies.
Row 18 | The primary source of information from which this dose object was constructed. The Source of Dose Information (Row 18) is independent of the Scope Of Accumulation (Row 6); e.g., it would be typical to have a scope of (113016, DCM, "Performed Procedure Step"), but a source of (113856, DCM, "Automated Data Collection") rather than (113858, DCM, "MPPS Content").

### TID 10002 Accumulated X-Ray Dose

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).

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.

### 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 switching of the irradiation source during the event shall not be treated as separate events, rather the event includes the time between 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.

Content Item Descriptions

Row 3 | If the image generating entity does not assign a DICOM UID to the irradiation event (e.g., for non-digital imaging equipment), the application generating this report shall assign a UID. In the case of non-integrated cassette-based equipment, a standalone Detector will generate UIDs for the Events it observes. If the X-Ray Source component of the equipment also reports information, it too will generate UIDs for the Events it creates. A downstream system (e.g., a workstation or the Dose Information Reporter itself) may combine the two reports into a composite report, and match up the events based on details such as the time information, and use the UIDs of the X-Ray Source.
Row 6 | Provide DateTime the application of X-Ray started. This shall correspond to the start of the first irradiation in the Irradiation Event, which defines the starting point for the calculation of Row 36 "Irradiation Duration".
Row 17 | The target region is the anatomy exposed.
Row 21 | A text definition of the Reference Point (RP) used for RP-related dose values.
Row 22 | A coded definition of the Reference Point (RP) used for RP-related dose values

Row 15 | Exposure as measured/recorded by system, either as a single total value, or as multiple values. If multiple values are provided, their number shall match the value in Row 7 "Number of Pulses".

Row 23 | Collimated area at the receptor plane.
Row 27 | The device that produced the irradiation in this Irradiation Event. I.e., the X-Ray source.
