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 | Provide the model and position of each X-Ray attenuator described in TID 10047, if known.
Row 5 | Each X-Ray attenuator model and position description includes the identification of the X-Ray attenuator, which shall match the identification used in TID 10047.
Row 6, 7, 8 | Reference to a three-dimensional model of the X-Ray attenuator
Row 9 | 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 attenuator to the RDSR reference coordinate system. The translation described by this matrix indicates the position and orientation of the X-Ray attenuator within the RDSR reference coordinate system. The RCS for the X-Ray attenuator shall be a right-handed Cartesian coordinate system. If the model data in Row 6, 7, 8 was not originally in a right-handed Cartesian coordinate system, it must transformed prior to inclusion in this template.
