Adding images to an Integrated Multimedia Patient Record

Project Details


The basic research and prototype developments of this project should lead to new developments in : (1) the integration of images into the patient medical record and (2) remote expert consultancy and image-based co-operation between experts. In the prototype developments, emphasis is on state-of-the-art architectural concepts for designing open systems, and in the adherence to medical as well as industrial standards. In the longer-term prototype research, attention is spent to emerging World Wide Web technology and the new capabilities offered by multiresolution image compression. In the experimental research part, emphasis is on ways to implement new services in (1) multimedia information access, (2) multimedia and hypermedia radiological reporting, and (3) real-time and delayed-time hypermedia remote co-operation. In this project, VUB-IRIS will investigate the adequacy/performance of different compression schemes, in the context of progressive transmission of medical images via off-the-shelf low-bitrate technologies, like e.g. ISDN. Our research will mainly focus on wavelet-based techniques. Different kinds of wavelet base-functions will be investigated and an accompanying quantizer/coder for lossy compression of the wavelet coefficients will be elaborated, taking into account the performance requirements (computation time, available bit-rate) of the global data-compression. The wavelet based approach will also be compared with DCT (Discrete Cosine Transform) and SIC-based (Segmented Image Coding) approaches. In order to validate the quality of the different transmission schemes, a real-time demonstrator will be developed. The consortium unites (1) commercial companies (AGFA-GEVAERT N.V. [Coordinator], Bell Telephone Manufacturing Company N.V., Cipal-ICA vzw) focusing respectively on the imaging part and on the patient medical record part, (2) research groups (Katholieke Universiteit Leuven, Universiteit Antwerpen UIA and Vrije Universiteit Brussel), which have experience in bridging the gap between technological and medical experts, and (3) future users (Algemeen Ziekenhuis Middelheim, Universitaire Ziekenhuizen Leuven). The project is funded by IWT.
