JPEG2000 Codec And Its Application In Medical Image

An increasing number of medical imagery is created directly in digital form. Clinical picture archiving and communication systems (PACS), as well as telemedicine networks require the storage and transmission of this huge amount of medical image data. Efficient compression of these data is crucial.Lossless techniques allow exact reconstruction of the original imagery, while lossy techniques aim to achieve high compression ratios by allowing some acceptable degradation in the image. Lossless compression does not degrade the image, thus facilitating accurate diagnosis, of course at the expense of higher bit rates, i.e. lower compression ratios.An excellent compression arithmetic should have high compression rate and keep the diagnosis character. Generally, lossy and lossless arithmetic are very different in design .So it is a very challenge task to find an arithmetic that can be used in both the two method.The new still image compression standard, JPEG2000, offers a lot of features and fulfils the requirements for the medical imagery compression. Many researchers have extensively worked on its potential for the medical images.The goal of this paper is to describe the JPEG2000 codec and Its application in. Medical Image. As an example, we illustrate how a JPEG2000 codec can be used to compress Medical Image. We can conclude that in lossless compression the compression rate can be up to 3.2 and in lossy compression when the...
