DICOM Structured Reporting

1. DICOM Structured Reporting Relevant Patient Information Query Service Class Overview

2. Scope and Field of Application The Relevant Patient Information Model provides a means to exchange specific information from a patient’s medical history, captured in the form of a Structured Report Content Sequence. The associated SOP Class supports the query (C-FIND) of Relevant Patient Information (RPI) from information or reporting systems that typically possess this information. Systems that need to capture a patient’s relevant information at a given point in time, for use during image acquisition, CAD processing, or image interpretation, would use this query mechanism. The relevant patient information would be received in the form of a Structured Report Content Sequence, which could be parsed and used by the system to do its work, and potentially be incorporated into a Structured Report composite IOD created by the image acquisition, CAD processing, or image interpretation system.
