摘要： A simulator for simulating a first object and a second object that is coupled to the first object is disclosed. The simulator models the first and second objects as a plurality of segments, with each segment having a plurality of nodes connected by one or more edges. The simulator then indexes each of the nodes and couples at least one node of the first object to a node of the second object. The indexing and coupling is based on the current simulated position of the first and second objects. The simulator then generates and solves a linear system of equations Ay=b from the indexing, and updates a position of each of the nodes. The simulator flow then dynamically re-indexes the nodes, and continues in a loop.

摘要： A method of simulating a flexible object such as a catheter includes modeling the flexible object as a plurality of segments in which each segment has a plurality of nodes connected by one or more edges. The method further includes modeling each segment as a plurality of tetrahedral elements formed by the nodes and the edges to generate a tetrahedral finite element model. The method further includes indexing each node so that a maximum difference between a first index of a first node and a second index of a second node is bounded and is approximately equal to s*k, where s is the maximum number of segments connected at one node and k is a maximum number of nodes that belong to one segment.

摘要： Embodiments of systems, methods, and computer-readable media for real-time winding analysis for knot detection are disclosed. For example, one embodiment of the present invention includes a method having the steps of receiving a first wrapping signal indicating a first wrapping of the simulated thread around a second tool to create a first loop. The method further includes determining a first wrapping direction based at least in part on the first wrapping signal; receiving a first tightening signal indicating a pulling of a first end of the simulated thread through the first loop; determining a first half-hitch based at least in part on the first winding direction and the first tightening signal; and outputting the first half-hitch. In another embodiment, a computer-readable media includes code for a carrying out such a method.

摘要： A system and method for surgical visualization transform a cut procedure into a visual representation, e.g., during resection via a cutting tool. The system and method obtain shape data, e.g., bone shape data for the bone to be resected, and generate a CSG object model such as a bone model. Another CSG model is also generated, based, for example, on the cutting tool shape. During resection, tool position data is collected and multiple CSG subtraction models are generated based on the cutting tool model and the position data. The CSG bone model and subtraction models are used to create an image space visual representation by merging the CSG subtraction models into a single merged CSG subtraction model and subtracting the single merged CSG subtraction model from the CSG bone model.

摘要： A computer-implemented method determines an orientation parameter value of a prosthetic component. The method includes receiving a first desired separation distance between a tibial prosthetic component and a femoral prosthetic component at a first flexion position of a knee joint and estimating a first estimated separation distance between the tibial prosthetic component and the femoral prosthetic component at the first flexion position of the knee joint for at least one potential orientation of the femoral prosthetic component. The method also includes determining a first orientation parameter value of the femoral prosthetic component by comparing the first estimated separation distance to the first desired separation distance and outputting the first orientation parameter value via a user interface.
