Abstract
Medical images play a significant role in diagnosis at the present time. The diagnosis information is also important particularly in patient treatment data, the results and other confidential information which cannot be disclosed according to judgment and ethics. These data are exported with the images and will be protected generally. This article presents a high-efficiency technique for hiding information in images that is reversible without loss. This algorithm has been tested on medical images from different modalities which are diverse in nature and structure such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET) and ultrasound (US). In summary, our processes have been analyzed in many aspects, for the embedding data capacity and image distortion after embedding. The test results demonstrated the efficiency of our approach that could embed a large amount of data with low distortion. ©2012 IEEE.
