A Review on Medical Image Compression Methods and Their Characteristics

Medical images are employ for disease detection. The problem faced by the physician and the team is to store them using less space. A large numbers of patients come in a day even in small hospitals and this become necessary to store the health data of each of the patient. Medical images including radiography, magnetic resonance (MR), mammography and ultrasonic images, brain MRI, CT images and so on, this images are big size data and having such numerous amount of patient the storage this kind images occupies more area in storing devices. So there is need is to compress the medical images for storage. The another requirement of medical image compression is the transmission of medical images for second opinion of the specialist doctors who is far away from the patient. So there is need to compress the images to be resolve the verity of problem related to storage and transmission, so this long term rapid transmission is not prohibited without image compression. To make the medical images more useful and process-able and also to reduce the transmission time the image must be compressed. By compression appearance of image become more visual too and compression it will help to reduce the transmission error as less data will transmit.
