Purpose

DicomModifyMLToRTDosePlugin converts inCSOList, inRTPlan, input0 and input1 to Structure Set ROI Sequence (3006,0020), RT Dose ROI Sequence (3004,0010), ROI Contour Sequence (3006,0039), Referenced Frame of Reference Sequence (3006,0010) and Referenced RT Plan Sequence (300c,0002). The sequences can be added to a DICOM tree via ModifyDicomTree along with other tag modifications. For all modifications performed by this module see Details section.

Usage

See example network to see how to use DicomModifyMLToRTDosePlugin.

Details

The module performs the following:

  • Dose Summation Type (3004,000a) is set to Dose Summation Type.

  • Referenced RT Plan Sequence (300c,0002) is added. If Dose Summation Type equals PLAN, FRACTION, BEAM, FRACTION_SESSION, BEAM_SESSION, one item item0 is added:

    • item0’s Referenced SOP Class UID (0008,1150) is set to 1.2.840.10008.5.1.4.1.1.481.5.

    • item0’s Referenced SOP Instance UID (0008,1155) is set to inRTPlan’s SOP Instance UID (0008,0018).

    • Referenced Fraction Group Sequence (300c,0020) is added to the item0. Sequence contains one item item1:

    • z - voxel size of input0 along z axis.

    • n - number of slices of input1 - 1.

• Structure Set Module:

  • Referenced Frame of Reference Sequence (3006,0010) is added. Sequence contains one item item0:

        • item2’s Series Instance UID (0020,000e) is set to input0’s Series Instance UID.

        • Contour Image Sequence (3006,0016) is added to the item2. For each input0’s slice with at least one CSO an item item3 is added:

          • item3’s Referenced Frame Number (0008,1160) is set to 1.

          • item3’s Referenced SOP Class UID (0008,1150) is set to input0’s SOP Class UID (0008,0016).

          • item3’s Referenced SOP Instance UID (0008,1155) is set to slice’s SOP Instance UID (0008,0018).
