Abstract
Medical imagies with high resolution are coded to be archived and communicated in MPACS. In this paper, we have studied on coding of Cardio-Angiography. Our coding technique is Subband-Vecter Quantization. This techniquec is irreversible coding method. This technique's advantages are removing blocking effect and edge degradation, adapting for drastic image change because of dye injection and fast decoding. We achieved good results fur Cardio-Angiography data, but the study on more sophiscated motion estimation techniques and VQ techniques must be performed.
