DICOM WG10 Kamakura April, 2004 page 7 Scenario 5 & 6

DICOM WG10 Kamakura April, 2004 page 8 Context Digital imaging and communications in Radiology is relatively mature Clinicians have more and more access to digital equipment (PC, Web, emerging EPR/EMR) Communication channels are available (Intranet, Internet, CD/DVD)

DICOM WG10 Kamakura April, 2004 page 9 Limitations of DICOM Order / prescription enriching diagnosis Report display and « push » Significant images selection Access to images and reports Multi-domain patient identification Collaboration on images and reports (for the mid term future)

DICOM WG10 Kamakura April, 2004 page 10 Order / prescription Orders « managed » by HL7 but its radiology specific content has to be mapped to DICOM Lack of structured content (CPOE, JJ17xx) New Structured Prescription, retrieved by interpretation WS? If defined, to be integrated in SR

DICOM WG10 Kamakura April, 2004 page 11 Report The main result waited by the clinician A « push mode » has to be defined A mapping on CDA has to be defined, to be managed as other documents by clinicians A « presentation mode » has to be defined (stylesheet to PDF?) to replace the paper

DICOM WG10 Kamakura April, 2004 page 12 Significant images Crucial problem of selection, required for saving clinician time and largely under done by radiologists for saving their time Highlighted by large CT and MR, even on CD distribution of images Requires to defined a « push mode » of a set of selected images/objects By default, action close to the « print » one

DICOM WG10 Kamakura April, 2004 page 13 Access to images and reports Clinician are more and more manipulating DICOM objects but DICOM protocol can not reach them easily Extension of WADO kind mechanisms for: –Querying DICOM objects (IHE ITI RID kind); –"Set of objects" retrieval (example a series or a KOS referring a list of images); –"Left part" of the URI (using Namespaces for solving the problem "transposition" of the references between different contexts); –Refining the access to only a part of the DICOM object, either a set of Tags for example, or a part of the image or the sequence (beyond the single frame number).

DICOM WG10 Kamakura April, 2004 page 14 Multi-domain patient identification How far DICOM shall take into account the multi-domain patient identification? Analyze the impact of the DomainID extension of the Patient Header (CPxx) Typical use case on short term: reload of DICOM CD in another radiology department, with patient reconciliation
