Abstract

This paper describes the application of a Realtime Digital Disk (RTDD) with processing capabilities and the increased functionality the RTDD brings to a PACS system. While the display and acquisition of images at 30 frames per second is the obvious advantage of the RTDD in PACS, the image processing and image enhancing functions make its use more effective. Realtime presentations include window and level of greater than 8 bit images, intensity transformation of 8 bit images, shape table and tiling presentation, and subsampling. Movie loop and three dimensional reconstruction sequences are viewed in realtime. Edge enhancement, smoothing, interpolated zoom, unsharp masking and other convolution filtering are near realtime presentations. Compression and decompression, histogram equalization and other transforms are performed in just a few frame times.
