摘要： A method of determining a three-dimensional (3D) position of a catheter tip includes: compensating a 2D position of the tip of the catheter for respiratory motion to generate a compensated 2D catheter position, generating weighted sample points around the compensated 2D catheter position, determining correspondent points of the weighted sample points in a 3D image, computing a weighted mean and a weighted covariance of each correspondent point, and determining the 3D position of the catheter tip in the 3D image from a fusion of the weighted means and weighted covariances.

摘要： A method for reconstruction of a 3D volume from a set of projection images recorded by a tomography apparatus using penetrating radiation in the field of dental medical applications takes into account a given value of at least one parameter. Simulated projection images are generated which correspond to at least a subset of the recorded projection images by simulating a projection of the penetrating radiation through the reconstructed 3D volume taking into account said given value of the at least one parameter. A re-projection error is determined by comparing the simulated projection images (with the corresponding recorded projection images. The re-projection error is then minimized by changing the value of the at least one parameter and by iterating over the above steps.

摘要： A method for visualizing one or more objects of interest within a volume of imaging data includes the steps of receiving a volume of imaging data and displaying the one or more objects of interest within the volume by adaptively changing the amount of information displayed from the volume based on (1) a viewing direction of the volume, (2) a position of the one or more objects of interest within the volume, and (3) importance values of materials within the volume.
