We propose a novel algorithm for the retrieval of images from medical image databases by content. The aim of this article is to present a content-based retrieval algorithm that is robust to scaling, with translation of objects within an image. For the best result and efficient representation and retrieval of medical images, attention is focused on the methodology, and the content of medical images is represented by the regions and relationships between such objects or regions of the Image Attributes (IA) of the objects. The CBMIR employs a new model in which each image is first decomposed into regions. The similarity measurement between images is developed based on a scheme that integrates the properties of all the regions in the images using regional matching. The method can answer queries by example. The efficiency and performance of the presented method has been evaluated using a dataset of about 5,000 simulated, but realistic computed tomography and magnetic resonance images, from which the original images are selected from three large medical image databases. The results of our experiments show more than a 93 percent success rate, which is satisfactory.
