Computer assisted surgery requires a registration process that identifies the position of the patient within the operating room. A common approach is to attach reflective markers to the patient which are illuminated and detected by a stereo camera. In order to reduce the logistic effort of operation planning, it is desirable to perform an automatically marker-less registration. In order to implement...
Accurate three dimensional scanning of surfaces, especially on humans, is more and more relevant. The usage of laser projection systems is widespread. However, a medical certification Class I, high accuracy, a flexible and not static handling as well as the ability to record from more than one direction has never been combined in a single device. Our project aims at the ideal setting for an easy to...
This paper describes a method for measuring the shape accuracy of a cylindrical hole which is created by means of an automatically power-controlled laser system using navigated control. In dental surgery, drills or mills are used for bone treatment. For most patients the use of these instruments is very inconvenient. Furthermore, the bone treatment with rotating instruments can lead to thermal necrosis...
