ABSTRACT
Medical Image has been increasingly applied in clinical diagnosis and treatment.It is very important to make use of large numbers of images in medical image management system in order to help clinician to analyze and diagnose.The traditional information retrieval techniques are not fit for retrieving large scale medical image databases.It is a very promising idea to introduce Content-based Image Retrieval(CBIR) technique into indexing medical image databases.The structure of the Content-based Medical Image Retrieval System(CBMIR) is introduced,and the key problems are mainly investigated,which included image segmentation,feature extraction,similarity searching and feedback mechanism.At last,the status and development of CBMIR are discussed.
