Technologist may or may not enter something at the console for the accession number. The key that identifies the order is the Accession Number, which is copied from the worklist to the image header and is used by a radiologist to identify the diagnostic report. For more information, please see this page. There are similar difficulties answering the same questions we saw for the DICOM treatment planning stations, but it is complicated further by the different data format, applications, and ways of identifying a patient. In this blog, I will examine additional problems with unstructured data that exist where integration is relatively well defined in clinical environments such as radiology and oncology. IHE defines this transaction using a DICOM Structured Report. An imaging protocol has three main components: imaging modality, anatomical region of interest, and acquisition parameters. The accession number is supposed to uniquely identify the studyon the information system. Slice Thickness:Nominal slice thickness, in mm. DICOM Parts 3, 4, and 6, NEMA.
