Imaging Use Case forUCUM Development Tool Kit (DTK) Janice Chilli 2/25/08
Background and Goals • Opportunity for imaging workspace to define their requirements for this tool for the UCUM Development Tool Kit (DTK). • Define the AIM UoM use case as depicted in the AIM model for attribute: CalculationResult:unitOfMeasure. • Develop an Imaging use case(s) based on all imaging applications (AIM, XIP, Middleware, NCIA, RIDER, LIDC, AVT, DICOM Ontology). • Review UoM list developed by imaging workspace last fall. • Identify any characters used as imaging UoM that are not part of the 7-bit US-ASCII character set. • Determine if single UoM implementation for all imaging applications is possible (values and UoM as separate attributes or UoM embedded in attribute?)
Question 1 Imaging Units of Measure List • Identify Units of Measure needed by the Imaging applications (AIM, XIP, Middleware, NCIA, RIDER, LIDC, AVT, DICOM Ontology, anticipated projects) • Status of list started by workspace last fall. • Dr. Channin to provide compiled workspace UoM list or UoM emails to Janice.
Question 2 7-bit US-ASCII OK? • Identify any characters used as an imaging UoM that are not part of the 7-bit US-ASCII character set. • Identify use case for these characters. • RIDER/LIDC (Mike McNitt-Gray): Can UCUM handle Greek letters like alpha, gamma in UoM? • WS: Any other imaging use cases for non-DICOM UoM?
Question 3AIM Use Case for UCUM DTK • CalculationResult class:unitOfMeasure • Is the anticipated use for the UCUM tool to electronically “validate” the UCUM unit of measure via a get to the this tool? • Is the anticipated use for the UCUM tool to “create” the UCUM unit of measure? • How will exception handling of non-UCUM strings be handled? Current UCUM DTK requires human intervention. • Do any of the other measurements in AIM model need a UoM attribute (GeometricShape:lineThickness, Dimension:size, Data:value)? • Set up Imaging developers and UCUM DTK call (Janice & Paul) to discuss imaging requirements with UCUM DTK team. Include representatives from AIM, XIP, Middleware, NCIA, RIDER, LIDC, AVT, DICOM Ontology.
Next Steps • Clearly define Imaging Application Use Cases/interaction with the UCUM DTK. • Confirm that the 7-bit US ASCII character set is sufficient to meet the needs of the imaging UoM attributes. • Develop an Imaging use case(s) as input to the UCUM DTK requirements. • Workspace to consider separate versus embedded UoM and impacts on current and proposed workspace applications.
