34. The DICOM Standard
The Digital Imaging and Communications in Medicine (DICOM) Standard is a detailed specification that describes semantics and syntax for exchanging images and associated information. The standard applies to the operation of the interface which is used to transfer data in and out of an imaging device.

36. What is DICOM Digital Imaging and Communication in Medicine
Standard for communication of images and image related information between devices
International in scope
All biomedical imaging
Voluntary standard

37. DICOM is Biomedcial Informatics
“the storage, retrieval, sharing, and optimal use of biomedical information, data, and knowledge for problem solving and decision making.” Edward Shortliffe
“model formation, implementation of the model, application of implementaion to the real world, evaluation of the implementation” Titus Schleyer
