Analysis of the compression ratio and quality in medical images

Abstract

In the modern medical information systems documents are stored in the centralized storage. Choosing a proper, for the medical image storage, compression format is an important problem. This paper analyzes medical image compression in popular compression formats. For the compression format comparison there is proposed image quality evaluation algorithm based on the calculation of the mean exponent error value. Presented image quality evaluation experiment. Analyzed the distribution of the errors in medical images and explained the causes determining better than usual compression effect. Proposed complex solution of the medical image compression problem and specified compression format most suitable for the medical images.
