The Patient Support Position Macro invoked by Patient Support Position Sequence (3006,00CB) allows the exchange of device-specific parameters for the patient support device. Both coordinate systems are expressed in millimeters. The patient-oriented coordinate system is identified by the Frame of Reference UID (0020,0052) of the SOP Instance it is used within. For further information on the definition of the Equipment Frame of Reference, see Section 10.39.1.1. The Equipment Coordinate System is identified by the Equipment Frame of Reference UID (300A,0675). This matrix AM Bdescribes a rigid transformation of a point ( Bx, By, Bz) with respect to the Patient coordinate system into ( Ax, Ay, Az) with respect to the Equipment Coordinate System as defined in Section C.7.6.21.1. The Image to Equipment Mapping Matrix (0028,9520) describes the relationship between the Patient-oriented coordinate system and an Equipment Coordinate System. >Include Table 10.40-1 “Patient Support Position Macro Attributes”.ġ0.39.1.2 Image to Equipment Mapping Matrix and Patient Support Position Macro Zero or one Item shall be included in this Sequence.
