Content Item Descriptions

Row 2 | The DateTime of the beginning of the time period over which the content items are applicable.
Row 3 | The DateTime of the end of the time period over which the content items are applicable.
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 Output Measurement Point Position describes the position where the measure or machine estimate of radiation output occurs. It is described in the X-Ray source reference coordinate system. It may be the same position as the reference point position (the reference point may be defined in TID 10041).
Row 7 | If a reference point is defined in TID 10041, its position in the X-Ray source reference coordinate system shall be described here.
Row 9 | Provide the model and position of each X-Ray filter described in TID 10046, if known.
Row 10 | Each X-Ray filter model and position description includes the identification of the X-Ray filter, which shall match the identification used in TID 10046.
Row 11, 12, 13 | Reference to a three-dimensional model of the X-Ray filter
Row 14 | A 4-by-4 matrix of dimensionless numbers of the form defined in Section C.20.2.1.1 “Frame of Reference Transformation Matrix” in PS3.3 . The matrix describes the rigid transformation matrix (including translation and rotation) that transforms the reference coordinate system for the X-Ray filter to the X-Ray source reference coordinate system. The translation described by this matrix indicates the position and orientation of the X-Ray filter within the X-Ray source reference coordinate system. The RCS for the X-Ray filter shall be a right-handed Cartesian coordinate system. If the model data in Row 11, 12, or 13 was not originally in a right-handed Cartesian coordinate system, it must transformed prior to inclusion in this template.
