摘要
A device and method are disclosed for the pre-operative selection and determination of a position of an endoprosthesis using a first rear projection screen with variable opacity and a movable second rear projection screen located in front of the first projection screen in respect of rear projection. In at least one embodiment, the device also includes a first projection unit for generating at least one first projection of the region of a subject in which an endoprosthesis is to be fitted, onto the first rear projection screen, and a second projection unit for generating at least one second projection of the endoprosthesis onto the second rear projection screen, the scaling of the first and second projection being identical. In an alternative embodiment, the second rear projection screen can be omitted. At least one embodiment of the invention offers the advantage that fitting can take place in any anatomical slice planes and that the experience of users of an X-ray film/template technique can be applied.
