PROCESS FOR PLANNING AND MONITORING A SURGICAL OPERATION

摘要

In a process for planning and monitoring a surgical operation, an operation area is defined. At least one reference image of the operation area is generated by non-invasively obtainable structural data and used to plan at least one incision surface along which tissues are to be separated during the operation. Then an image of the intended incision surface is generated which is superimposed on an actual image of the operation area or even projected on the operation area itself during the operation. A three-dimensional reference image is used as the basis in planning the incision surface. A three-dimensional image of the incision surface superimposed upon the reference image is generated. It is computer-supported by data from images produced in different way. The images represent the operation area in superimposed layers. In making the reference image, computer tomographs, nuclear spin resonance, ultrasonic and/or X-ray images of the operation area are assessed. The reference image is stored in the store of a computer as a logic record. The image of the incision surface is superimposed on the reference image. It rises visually from the reference image. The incision surfaces are represented as transparent or semi-transparent lines.
