For some dose analysis performed by RDSR consumers, identifying the specific type of equipment and/or clinical procedure supports more specific analysis and metrics based on the clinical practice.
This section provides guidance for RDSR encoding of procedures and type of equipment.
There are two places where procedure codes are defined in an RDSR:
·Codes for procedure in the RDSR structured content, specifically defined for the RDSR creator equipment. This is discussed in this section.
·Procedure codes provided in the SR document metadata, applicable to any SR, not discussed in this section. See Section C.17.2 SR Document General Module in PS3.3 , Referenced Request Sequence (0040,A370), Performed Procedure Code Sequence (0040,A372).
The Content Item (121058, DCM, "Procedure reported") allows distinguishing categories of X-Ray procedures such as projection X-Ray (e.g., angiography, electrophysiology, fluoroscopy, radiography, single frame acquisition etc.), mammography, and CT. Within the projection X-Ray procedures, the Content Item (122142, DCM, "Acquisition Device Type") indicates the type of equipment used, with possible values defined in the CID 10032 “Projection X-Ray Acquisition Device Type”.
The combination of the values of these two Content Items provides an indication of the modality and type of equipment used. However, the values remain quite general and do not allow inferring the precise clinical procedure performed.
Note that the (363703001, SCT, "Has Intent") with DCID 3629 “Procedure Intent” indicates the clinical intent of the procedure (e.g., Diagnostic, Therapeutic, Quality Control, Screening, etc.), which is not necessarily related to the type of clinical procedure.
The values in(121058, DCM, "Procedure reported") and (122142, DCM, "Acquisition Device Type") are used as conditions in the template TID 10002 “Accumulated X-Ray Dose” to specify the appropriate accumulated radiation dose quantities that are reported for each type of procedure and device.
Table UUUU.4.2.1-1 provides some examples of meaningful values of these two Content Items (121058, DCM, "Procedure reported") and (122142, DCM, "Acquisition Device Type") for the state-of-the-art Traditional RDSR.
