This section contains examples of encoding of Radiation Dose Structured Report.
In these examples, the following convention is used to describe the Content Items and values:
Each Content Item is described by the Code Meaning of the Concept Name
TID in which the Content Item is defined appears in the right column
If the value of the Content Item is a code, the example shows the code triplet
If the value of the Content Item is a number, the example shows the unit with its Code Meaning
Spanning rows that provide context in the examples are not encoded in the RDSR
Note that other alternative implementation patterns exist for these examples; the normative text in PS3.16 is constraining, these examples are not.
The following is an example RDSR for a routine XA procedure step combining diagnostic and interventional treatment. A single plane Interventional X-Ray acquisition system (Irradiating Device) performs an exam (one procedure step) with the following characteristics:
The top of the patient head is located at 25 cm from the table head in the direction of the table foot.
One focused anti-scatter grid is fixed on the detector housing.
One pulsed fluoroscopy Irradiation Event lasting 10 seconds, with no XA image recorded.
One rotational acquisition (CBCT) Irradiation Event, rotating at 10 degrees per second and acquiring 30 frames per second over an arc of 200 degrees. An XA image is recorded.
A dose map image is created at the end of the procedure step.
The irradiation is administered by the performing physician Dr. Hugh Mann and by the operator John Doe.
The irradiation is authorized by the performing physician Dr. Hugh Mann.
Table UUUU.5.1.1-1 illustrates one possible encoding of this example. Note that other alternative implementation patterns exist.

The following is an example RDSR for a routine CT study. In this example, a CT scanner performs a CT localizer scan and a single CT acquisition.
The irradiation is authorized by the referring physician who ordered the CT scan, Dr. Marcus Welby.
The irradiation is administered by the technologist, John Doe.
The dose check alert was configured for CTDIvol of 1 Gy, and the dose notification was configured for CTDIvol of 45 mGy. Neither the alert nor the notification was triggered during this study.
Table UUUU.5.1.2-1 illustrates one possible encoding of this example. Note that other alternative implementation patterns exist.
Table UUUU.5.1.2-1. CT Traditional RDSR
The following is an example RDSR for a routine CT study where the CTDIvol dose notification value is triggered (see [NEMA XR-25]). This example is largely identical to the example in Section UUUU.5.1.2 except for exceeding the notification value due to a change in scanning parameters.
The dose check alert was configured for CTDIvol of 1 Gy, and the dose check notification was configured for CTDIvol of 20 mGy (lower than the previous example).
The X-Ray Tube Current and Exposure Time per Rotation are both increased from the previous example, resulting in a proportional increase in Mean CTDIvol, CTDIfreeair, DLP, and Size Specific Dose Estimate. As a result of the increase in reported dose metrics and the decrease in CTDIvol Notification Value, a notification event is triggered.
Exceeding a notification value allows the encoding of a Reason for Proceeding and a Person Participant for the RDSR encoding. This example includes a reason (patient with high body mass index (BMI) ) and the technologist initials (from the scanner console log in). Note that following the [NEMA XR-25] standard describing CT Dose Check capabilities, a reason need not necessarily be entered by the operator to proceed with a scan, meaning this row may be blank or absent in some instances.
The remaining content of the RDSR is identical for all other nodes to the example in Section UUUU.5.1.2.
Table UUUU.5.1.2.1-1 illustrates one possible encoding of this example. Note that other alternative implementation patterns exist.

The following is an example RDSR for a routine radiography study. In this example, an X-Ray system performs the acquisitions with the following characteristics:
This is an integrated system, therefore the conditions of TIDs (i.e., X-Ray Detector Data Available, X-Ray Source Data Available, X-Ray Mechanical Data Available) are satisfied.
Two acquisitions are performed: one lateral and one Anterior-Posterior (AP) views of the lumbar spine, with the patient standing.
The dose is estimated at the detector plane (dose reference point definition).
The irradiation is authorized by the physician Dr. Hugh Mann.
