Index defining the order in which the Items in the Patient Support Position Device Parameter Sequence (300A,065D) are applied.
The value shall start at 1 and increase monotonically by 1.
Required if Patient Support Position Specification Method (300A,065C) equals DEVICE_SPECIFIC.
See Section 10.40.1.
Section 10.40.1
10.40.1 Position Parameters and Order Index
The Device Order Index (300A,065E) and the Patient Support Position Parameter Order Index (300A,065F) are applied sequentially, meaning all the Items in a Patient Support Position Parameter Sequence (300A,065B) are applied before proceeding to the Item in the Patient Support Position Device Parameter Sequence (300A,065D) specified by the next Device Order Index (300A,065E) value.
A vendor may specify codes that are not included in TID 175001 and/or a set of codes which is not identical with the set defined in Section 10.40.1.1 or Section 10.40.1.2. The vendor shall document the codes used in this Macro in the Conformance Statement, as well as the corresponding parameters, their geometric interpretation, and the order in which they will be applied. These parameters shall use UCUM units of mm for lengths and degrees for angles.
10.40.1.1 IEC 61217 Patient Support Device
Devices using the [IEC 61217] coordinate systems to define geometric settings for the Patient Support device shall use the codes in Table 10.40-2 in the order specified in column Patient Support Position Parameter Order Index (300A,065F). Other codes shall not be used.

10.40.1.2 Isocentric Patient Support Device
Devices using an isocentric representation to define geometric settings for the Patient Support device shall use the codes in Table 10.40-3 in the order specified in column Patient Support Position Parameter Order Index (300A,065F). Other codes shall not be used.
