Abstract

It was recognized early on that the digitization of medical information would advance the efficiency of diagnostic technology. However, the digitization of image data, which makes up the majority of medical information, is dependent on advances in technologies such as input, processing, transmission, storage, and display. Insufficient advances in such technologies has effectively limited the digitization of image data for medical use. The result of this has been non-networked systems or LANs confined to a single hospital. Such isolated systems integrate only portions of digital medical images such as x-ray computer tomography (CT), magnetic resonance (MR), and computed radiography (CR). Fortunately, recent advances in the areas of super high definition image I/O, high-quality encoding, ATM-based high speed transmission, and high-capacity storage has turned the tide in favor of the digitization and networking of all medical information. This paper focuses on the digitization and networking of medical image information used within hospitals and provides a multifaceted study of the technologies necessary for these advances. This allows us to discuss the present state of related technical developments and the level that has been attained so far. In addition, we have targeted image information that demands the highest level of quality (radiological and pathological images) for application in medical diagnosis using super high definition images, which have a spatial resolution of at least 2048 by 2048 pixels and a temporal resolution of at least 60 frames per second with progressive scanning. We cover the concrete issues and approaches to solutions that must be investigated when building and networking a digital system.
