TID 10048 Radiation Output

The description of the radiation output at the output measurement point. If the output measurement point position (TID 10051 Row 5), X-Ray source transformation matrix (TID 10051 Row 5), or X-Ray source rotation angle (TID 10051 Row 8) are updated, this TID must also be updated. The TID may also be updated following changes to other machine characteristics (e.g., tube potential).

Content Item Descriptions

Rows 2, 3

The DateTime of the start and end of the radiation output measurement or calculation. This radiation output measurement window shall not overlap with the radiation output measurement window of any other instance of this template within the same RDSR.

Row 4

Identification the X-Ray source. This designation shall not change for a given source throughout the entire RDSR. For systems with multiple X-Ray sources, each source shall be described with a separate instance of this template.

Row 5

The accumulated air kerma over the period of time specified by Row 2 and 3.

Row 6

The table is encoded as a two-column table, consisting of multiple rows describing corresponding values of DateTime and accumulated air kerma over the period of time specified by Row 2 and 3. The number of rows in the table is not constrained.

The DateTime value in the first row of the table shall not be before the DateTime value in Row 2, and the corresponding air kerma value shall indicate the accumulated air kerma between the DateTime in Row 2 and the specified DateTime of the first row. Each subsequent row describes the accumulated air kerma between the DateTime in the previous row and the current row. The final DateTime value shall not be after the end DateTime value specified in Row 3.
