Referenced RT Radiation Sequence

(300A,0630)

1C

A set of RT Radiation Instances for which the positioning parameters apply.

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.
