Content Item Descriptions

Rows 2, 3

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

This period of time shall not span a period during which the value of output measurement point position (TID 10051 Row 5), or the X-Ray source transformation matrix (TID 10050 Row 5), or the corresponding X-Ray source rotation angle (TID 10050 Row 8) change for the same X-Ray source (as identified by the value of Row 4 in each of those templates).

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.

If this row is present, the period of time specified by Row 2 and 3 shall not span a period during which the value of output measurement point position (TID 10051 Row 5), or the X-Ray source transformation matrix (TID 10050 Row 5), or the corresponding X-Ray source rotation angle (TID 10050 Row 8) change for the same X-Ray source (as identified by the value of Row 4 in each of those templates).

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.

In the first table row, the value in COLUMN 1 shall not be less than the value of Row 2 of this TID. In the last table row, the value of COLUMN 1 shall not exceed the value of Row 3 of this TID.

For the first table row, the air kerma value in COLUMN 2 shall indicate the accumulated air kerma between the DateTime in Row 2 of this TID and the DateTime of COLUMN 1 of the first table row. Each subsequent table row describes the accumulated air kerma between the DateTime of the previous table row and the current table row.

For each table row, the defined period of time shall not span a period during which the value of output measurement point position (TID 10051 Row 5), or the X-Ray source transformation matrix (TID 10050 Row 5), or the corresponding X-Ray source rotation angle (TID 10050 Row 8) change for the same X-Ray source (as identified by the value of Row 4 in each of those templates).
