Basics of digital image processing

Abstract

Medical imaging devices such as CT and MR have developed remarkably, and many of them have been used in clinical examination. At the same time, because computer performance has drastically improved, many of clinical applications for medical images have been developed actively. Many of these clinical applications are focused on throughput, and is designed so that the user can get the result without having to know the details. Therefore, many processes in these applications have been black box, users can not know the details of them. However, use of the basic knowledge about digital image processing, users can infer what kind of algorithms are used in clinical application. This article provides basic knowledge of digital image processing and medical image processing algorithms frequently used in clinical applications.
