Abstract
In a process for planning and monitoring a surgical operation, an operation site is established. At least one desired image of the operation site is generated from structural data which can be obtained by noninvasive means, and the planning is based on at least one section surface along which tissue is to be severed during the operation. An image of the planned section surface is then generated, which image is superposed during the operation on an actual image of the operation site or is projected onto the operation site itself. A three-dimensional desired image is used as the basis for planning the section surface. A three-dimensional image of the section surface is generated which is superposed on the desired image. It is created by computer-aided means from data taken from images generated in different ways. The images show the operation site in layers, each lying on& above the other. Computed tomography, nuclear magnetic resonance, ultrasound, and/or X-ray images of the operation site are evaluated when constructing the desired image. The desired image is stored as data record in the memory of a DPU. It is displayed on an image reproduction device for planning the operation. Th…
