DICOM and Image Ontology Image Ontology Workshop 2006 Stanford University Anand Kumar MD, PhD, MBA IFOMIS, Univ. of Saarland, Germany. Siemens Medical Solutions, Germany. BIOMEDICALONTOLOGYBIOMEDICALONTOLOGY
BIOMEDICALONTOLOGYBIOMEDICALONTOLOGY Digital Imaging and Communications in Medicine DICOM Joint standard from American College of Radiology and National Electronic Manufacturer’s Association A standard method for transferring images and associated Information between devices manufactured by vendors Addresses the needs particularly of Radiologists
BIOMEDICALONTOLOGYBIOMEDICALONTOLOGY Information Object (Class): An abstraction of a real information entity (e.g., CT Image, Structured Report, etc.) which is acted upon by one or more DICOM Commands Synonym of Information Object Definition (IOD) Basic definitions Service Class: A structured description of a service which is supported by cooperating DICOM Applications using specific DICOM Commands acting on a specific class of Information Object.
BIOMEDICALONTOLOGYBIOMEDICALONTOLOGY Composite Information Object Class: May additionally include Attributes which are related to but not inherent in the real-world entity. E.g. Patient Name together with Computed Tomography Image Information Object Class Information Object Classes Normalized Information Object Class: Includes only those Attributes inherent in the real-world entity represented. Expresses the communication requirements of images where image data and related data needs to be closely associated.
