ACR-NEMA 2.0-based teleradiology system

摘要

Abstract: Existing teleradiology systems rely almost exclusively on frame-grabbed images from a video source to input data from a variety of modalities. This report details implementation of a teleradiology system which uses an ACR-NEMA gateway to access imagery from a variety of modalities with the full dynamic range of the original data. Such a system allows the user to use the full capability of window and level control to adjust the gray level of the resulting display. The penalty is that since most teleradiology systems transfer 8-bit data and most existing ACR-NEMA modalities transfer 12-bit data in a 16-bit pixel format, transmission times are potentially longer. This may be addressed to some extent with more sophisticated data compression. Ultimately the availability of faster telecommunications services to remote locations such as a radiologist's home will provide a better solution. !0
