    摘要： A system to assist in at least one of the evaluation of or the improvement of skills to perform minimally invasive surgery includes a minimally invasive surgical system, a video system arranged to record at least one of a user's interaction with the minimally invasive surgical system or tasks performed with the minimally invasive surgical system, and a data storage and processing system in communication with the minimally invasive surgical system and in communication with the video system. The minimally invasive surgical system provides at least one of motion data, ergonomics adjustment data, electrical interface interaction data or mechanical interface interaction data of at least a component of the minimally invasive surgical system in conjunction with time registered video signals from the video system. The data storage and processing system processes the at least one of motion data, ergonomics adjustment data, electrical interface interaction data or mechanical interface interaction data to provide a performance metric in conjunction with the time registered video signals to be made available to an expert for evaluation.

    摘要： A method for constructing one or more 3D scene models comprising 3D objects and representing a scene, based upon a prior 3D scene model and a model of scene changes, is described. The method comprises the steps of acquiring an image of the scene; initializing the computed 3D scene model to the prior 3D scene model; and modifying the computed 3D scene model to be consistent with the image, possibly constructing and modifying alternative 3D scene models. In some embodiments, a single 3D scene model is chosen and is the result; in other embodiments, the result is a set of 3D scene models. In some embodiments, a set of possible prior scene models is considered.

    摘要： Disclosed is a system and method for intra-operatively spatially calibrating an ultrasound probe. The method includes determining the relative changes in ultrasound images of a phantom, or high-contrast feature points within a target volume, for three different ultrasound positions. Spatially calibrating the ultrasound probe includes measuring the change in position and orientation of the probe and computing a calibration matrix based on the measured changes in probe position and orientation and the estimated changes in position and orientation of the phantom.
