Abstract

Videodiscs have introduced new capabilities in electronic storage including the publication of medical image databases. However, in several research programs conducted by the Lister Hill Center, evaluators found that videodiscs mastered in the standard NTSC television format did not deliver sufficient spatial and brightness resolution to reproduce medical images, such as radiographs, accurately enough for diagnostic usage. To explore techniques to upgrade the quality of medical monochrome images, a PC-based X-Ray Imaging System (XRIS) with CD-ROM storage and a standard video display was developed. XRIS was used as a test bed to evaluate digital storage as a means to improve the signal-to-noise ratio of electronically stored radiographs, and investigate the application of windowed imagingdisplay techniques to improve the spatial resolution. The system was designed for compatibility with small computer-controlled retrieval software and low cost NTSC displays. Test results showed that the XRIS prototype delivers improved image quality over the analog videodisc case both in terms of signal-to-noise ratio and spatial resolution.
