Management of medical images using wavelets-based multi-watermarking algorithm

Medical images of all types are produced in hospitals and health centers more than ever. The ease of production of medical images has been facilitated by the advancements in information and communication technologies. Traditional methods used to manage medical images fall short in coping with the great amount of information inherited in medical images. Therefore, there remains immediate need to develop efficient management strategies that work well with all types of medical images. In this paper, we apply a wavelet-based image multi-watermarking algorithm to implement three issues of great importance to the management of medical images. These issues are; image source authentication, image annotation, and image retrieval. Performance of the proposed algorithm was evaluated using four types of medical images; Ultrasound, X-ray, CT and MRI.
