Medical image compression has received great attention attributable to its increasing need to decrease the image size while not compromising the diagnostically crucial medical data exhibited on the image. Since the size of the image is primary matter of concern, to fix these issues compression was introduced. Over the past few years popularity of medical imaging lossless compression schemes rises radically because there is no loss of information. The only small part is more useful out of the whole image. Region of Interest Based Coding techniques are more considerable in medical field for the sake of efficient compression and to increase transmission bandwidth. The current work begins with the pre-processing of medical image. By assuming small part called roi part or deceased part in an image, Advanced SPIHT (ASPIHT) is applied. This paper propose techniques Region growing and Advanced Set Partition In Hierarchical Tree (ASPIHT) will enhance the performance of lossless compression and also enhance the Peak Signal to Noise Ratio (PSNR) and Compression Ratio (CR) than the Conventional SPIHT coding method.
