## B.3 HL7 CDA Release 2 Diagnostic Imaging Report Target Structure

The structure of DICOM SR Template TID 2006 is similar to DICOM SR TID 2000 Basic Diagnostic Imaging Report. References to the SR Diagnostic Imaging Report Transformation Guide (PS 3.20, Annex A) are used where the transformation of TID 2006 based reports is identical to that of basic diagnostic imaging reports. Details are outlined where new specific mapping requirements exist.

"Imaging Reports With Conditional Radiation Exposure and Protection Information"transformations that are identical to the "Diagnostic Imaging Report Transformation Guide" specification (PS 3.20, Annex A):

- Transformation of DICOM header module attributes as specified in Section A.5.1.1 Header (Level 1) of PS 3.20, Annex A.

- General transformation of DICOM sections as specified in Section A.5.1.2 Section (Level 2) of PS 3.20, Annex A.

- Transformation of "Structured Body (Level 3) " artifacts as specified in Section A.5.1.3 of PS 3.20) for: "Coded Observations", "Text Observations", "Image References and Measurements within Section", "Quantity Measurement + DICOM Composite Object References" (Use the linear measurement SNOMED code mapping as specified in Table A.5.1.3-4. Information on relevant DICOM objects referenced within the CDA target document's body and on the original DICOM SR document shall be included in the CDA DICOM object catalog section.).

- Transformation of "DICOM SR Observation Context" as specified in Section A.5.1.4 of PS 3.20 and the following subsections of this document: "Subject Context" (Section A.5.1.4.1), "Procedure Context" (Section A.5.1.4.2) and "Observer Context" (Section A.5.1.4.3).

PS 3.20, Annex A also contains information on HL7 data types mapping in Section A.8.
