Abstract: System for training an interventionalist to perform an invasive percutaneous or endoscopic intervention on an organ includes a pipe having a size and/or shape similar to a body vessel or tubular body cavity connected to the organ. An exit of the pipe simulates or represents an exit of the vessel or cavity at the organ. A tool is inserted at an entrance of the pipe and pushed through the pipe. A stereoscopic camera acquires images of an end portion of the tool as it exits from the pipe. A model generating unit generates a real-time 3D model of this end portion from the images. A merging unit merges in real time the real-time model and a pre-computed 3D model of the organ into a common environment displayed so that the interventionalist can see in real-time where the real-time model of the tool is located with respect to the pre-computed model.
