Future trends in 3D medical imaging.

Areas where significant progress is needed are outlined. A unified conceptual framework based on generic tasks, showing the intricacies and the dependences that exist among completely distinct and intensive research lines, is defined. True 3-D volume imaging devices are then discussed, with the main emphasis on vascular network reconstruction. Segmentation issues are briefly reviewed. The fusion of information dealing with image, signal, and model is described. Simulation and planning problems are discussed.
