摘要

Abstract: This paper reports on a lossy compression method applicable to cardiac angiography. Full frame DCT coding has been investigated, using an optimized bit allocation and quantization scheme. We compared it to the standard JPEG method in the environment of a cardiac angiography system with dedicated visualization devices and post-processing. At a compression ratio 12:1, the image quality appeared to be better than the JPEG base-line compression. Owing to the principle of our method, no blocking effect is induced, whereas this is a critical drawback of the JPEG algorithm. Furthermore, the sharpness of fine details is better preserved. !7
