WebThe table below contains the Data Dictionary from DICOM PS3.6 version 2013c. To use the DICOM grayscale standard display function (GSDF),[13] images must be viewed (or printed) on devices that have this lookup curve or on devices that have been calibrated to the GSDF curve. Even in this well-defined environment, problems still exist for data exchange. While retrieving the schedule information from the Radiology Information System, the Modality Worklist allows the images to be uniquely identified with keys matching the images with the radiology order and diagnostic reports. This information is loaded on a scanner prior to scanning and can be modified under special circumstances.
Pydicom For the other explicit data elements or implicit data elements, see section 7.1 of Part 5 of the DICOM Standard. Some older information systems generate numbers that are thoughtof as accession numbers that are not unique. The Service Class User (SCU: similar to a client), a modality or workstation, etc., uses the confirmation from the Service Class Provider (SCP: similar to a server), an archive station for instance, to make sure that it is safe to delete the images locally.
