“…However it must be recognized that in the remaining 21% of the implants the accuracy was low even tough this did not lead to significant complications. This outcome is similar to that of a previous clinical study [4] while differs from other in vitro studies [2,5,6] pointing to the need of well designed clinical studies on the subject.…”

“…In literature dealing with image guided surgery of the skull base, various authors have found targeting accuracies in the region of 1-2 mm helpful for the surgeon [6][7][8]. If we observe our results under assumption of a need of 2 mm targeting accuracy, the following conclusions can be derived: Targeting accuracy was sufficient for image-guided surgery of the maxilla, the midface, the orbit, and the anterior skull base.…”

In this paper we describe a technique which uses 3D shape modelling to plan reconstructive facial surgery for children born with facial asymmetry. The study used 3D images synthesized from high resolution CT scans. The aim of the technique is to supply the surgeon with a model based surgical plan that is surgically achievable, limited to a defined region of the patient's anatomy and smooth at the boundary between the operable and inoperable regions.

Re-Sternotomy is an important part of many interventions in cardiac or thoracic surgery. It is performed close to critical structures such as the ascending aorta or the heart with an inherent high risk of serious damage. In this paper, a system for improving the safety of this surgical procedure is presented. A soft tissue preserving saw is combined with automatic depth regulation. The depth is controlled on the basis of the optical characteristics (visible light) of the tissue aligned to the saw blade, which is analyzed using a color sensor. Detection of the blades' position in the bone during the cutting process is possible through the integration of an optical fiber into the tip of the saw blade. The automatic depth control is realized using a hysteresis controller running on a real time system. To show the feasibility of this approach, the sensor technology was integrated into a prototypal sternal saw and evaluated on artificial bone. As part of the experiments the influence of water for cooling and dust particles from the process on the systems control stability were analyzed. The system performed stable and accurate. Future research will focus on the control algorithm and cadaver trials.
