摘要： A medical system includes a shaft, multiple ultrasound transducers and a processor. The shaft is configured for insertion into an intra-body cavity of a patient. The multiple ultrasound transducers, which are distributed over splines that form a basket catheter at a distal end of the shaft, are configured to transmit ultrasonic signals in the intra-body cavity and to receive echo signals in response to the ultrasonic signals. The processor is configured to calculate a surface of the intra-body cavity by processing the echo signals using an ellipsoidal back-projection method, which reconstructs ultrasound-wave reflecting surfaces by performing at least one of applying back-projection summation over sub-sets of scattered echo signals distributed over respective sub-sets of constructed ellipsoids and applying a non-linear minimum operator over each of the sub-sets of distributed echo signals to generate a respective minimum value for each sub-set.

摘要： A system including a display and a processor. The processor is configured to: (i) receive multiple position measurements indicative of respective positions of an ablation electrode at respective times during an ablation procedure at an ablation site in an organ of a patient, (ii) estimate, based at least on the multiple position measurements, a quality index indicative of a stability of the ablation procedure at the ablation site, and (iii) visualize the quality index to a user on the display.

摘要： A method is provided. The method includes receiving, by a reconstruction engine executed by processors, inputs respective to an anatomical structure and computing, by a model-based fast anatomical mapping of the reconstruction engine, an initial transformation that selects parametric model that best fits the inputs. The method further includes executing, by the model-based fast anatomical mapping, an iterative optimization. The iterative optimization include constructing a statistical prior based on the parametric model and applying the parametric model to the inputs and the statistical prior to produce an isosurface of the anatomical structure. The method further includes generating, by the reconstruction engine, an output including the isosurface.
