Ever since the development of the first applications in image-guided therapy (IGT), the use of head-mounted displays (HMDs) was considered an important extension of existing IGT technologies. Several approaches to utilizing HMDs and modified medical devices for augmented reality (AR) visualization were implemented. These approaches include video-see through(More)
This paper describes an experiment and its results concerning research that has been going on for a number of years in the area of anthropomorphic user interface feedback. The main aims of the research have been to examine the effectiveness and user satisfaction of anthropomorphic feedback in various domains. The results are of use to all interactive(More)
We present a simple and rapid method for generation of perspective digitally rendered radiographs (DRR) for 2D/3D registration based on splat rendering. Suppression of discretization artefacts by means of computation of Gaussian footprints--which is a considerable computational burden in classical splat rendering--is replaced by stochastic motion of either(More)
BACKGROUND The complete resection of macroscopic colorectal peritoneal carcinomatosis (PC), followed by intraoperative intraperitoneal chemohyperthermia (IPCH) to treat residual microscopic disease, leads to cure in some patients. We report preliminary results on survival in a phase II study using oxaliplatin (LOHP). PATIENTS AND METHODS Twenty-four(More)
We discuss the approximation of the meanfield terms appearing in computations of the multi-configuration time-dependent Hartree–Fock method for the solution of the time-dependent multi-particle (electronic) Schrödinger equation by hierarchical matrices. We give theoretical error bounds for the cross approximation defined by low rank approximations of(More)
We are developing an optical see through head mounted display in which preoperative planning data provided by a computer aided surgery system is overlaid to the optical image of the patient. In order to cope with head movements of the surgeon the device has to be calibrated for a wide zoom and focus range. For such a calibration accurate and robust(More)
