  19. DICOM • Digital Imaging and COmmunications in Medicine • An evolving standard in digital medicine • DICOM • an image or file format • a networking protocol • built on top of TCP/IP • designed to store and transmit medical data An Introduction to Medical Imaging System

  20. DICOM • Official website • http://medical.nema.org/ • http://www.dicom.org.tw/index.jsp (Taiwan) An Introduction to Medical Imaging System

  21. Advantages (1) • Universal standard of digital medicine. • All current digital image acquisition devices produce DICOM images and work on DICOM networks. An Introduction to Medical Imaging System

  22. Advantages (2) • Excellent image quality. • DICOM supports up to 65536 (16 bits) shades of gray for the monochrome image display, still dominating many modalities. With this respect, converting DICOM images into JPEGs or bitmaps (with 256 shades of gray) makes them practically unusable for diagnostic reading. On the other hand, DICOM does include various image-encoding formats, from basic bitmapped data to wavelets. An Introduction to Medical Imaging System

  23. Advantages (3) • Full support for image-acquisition parameters. • Not only does DICOM store the image pixels, but it also records a multitude of other image-related parameters such as patient 3D position, physical sizes of the objects in the image, slice thickness, image exposure parameters, etc. This data enormously enriches the informational content of DICOM images, and facilitates processing and interpreting the image data in various ways - for instance, creating 3D images from the sequences of 2D CT slices. An Introduction to Medical Imaging System

  24. Advantages (4) • Complete encoding of medical data. • DICOM files and messages use about 4000 standardized fields ("DICOM dictionary") to convey various medical data - from patient name to image color depth to current patient diagnosis. This data is often essential for correct diagnostics. An Introduction to Medical Imaging System

  25. PACS • Picture Archiving and Communication Systems • complete medical systems with all hardware and software included, • Components • archiving servers (one or many, for online and deep storage) • diagnostic workstations • digital image acquisition devices • DICOM conformance statement • ensuring their conformance to the standard and interconnectivity.
