Required if Referenced RT Radiation Set Sequence (300A,0702) and Referenced RT Plan Sequence (300C,0002) are absent.

One or more Items shall be included in this Sequence.

>Include Table 10-11 “SOP Instance Reference Macro Attributes”

Referenced RT Radiation Set Sequence

(300A,0702)

1C

A collection of RT Radiation Sets for which the positioning parameters apply.

Required if Referenced RT Radiation Sequence (300A,0630) and Referenced RT Plan Sequence (300C,0002) are absent.

One or more Items shall be included in this Sequence.

>Include Table 10-11 “SOP Instance Reference Macro Attributes”

>Referenced RT Radiation Sequence

(300A,0630)

1C

A subset of the SOP Instances referenced in the RT Radiation Set SOP Instance for which the parameters apply.

Required if Treatment Position Group Sequence (300A,060A) is absent and the scope is limited to a subset of RT Radiation SOP Instances of the referenced RT Radiation Set.

One or more Items shall be included in this Sequence. The maximum number of Items is one less than the number of RT Radiation SOP Instances in the referenced RT Radiation Set SOP Instance.

>>Include Table 10-11 “SOP Instance Reference Macro Attributes”

>Treatment Position Group Sequence

(300A,060A)

1C

Treatment Position Groups defining patient positions for which the parameters apply.

Required if Referenced RT Radiation Sequence (300A,0630) is absent and Treatment Position Groups to which the positioning parameters applyare defined in the referenced RT Radiation Set.

One or more Items shall be included in this Sequence.

See Section C.36.10.1.3.

>>Referenced Treatment Position Group UID

(300A,0785)

1

Referenced unique identifier of the Treatment Position Group.

Referenced RT Plan Sequence

(300C,0002)

1C

A collection of RT Plans and/or RT Ion Plans for which the positioning parameters apply.

Required if Referenced RT Radiation Sequence (300A,0630) and Referenced RT Radiation Set Sequence (300A,0702) are absent.

One or more Items shall be included in this Sequence.

>Include Table 10-11 “SOP Instance Reference Macro Attributes”

>Beam Sequence

(300A,00B0)

1C

A subset of RT Beams included in the RT Plan SOP Instance for which the parameters apply.

Required if the scope is limited to a subset of RT Beams of the referenced RT Plan and the Number Of Beams (300A,0080) is not zero.

One or more Items shall be included in this Sequence. The maximum number of Items is one less than the number of RT Beams in the referenced RT Plan SOP Instance.

>>Referenced Beam Number

(300C,0006)

1

Beam Number identifying the referenced RT Beam or RT Ion Beam.
