Patent number: 11113899Abstract: A system includes a display and a processor. The processor is configured to compute a point P? on a virtual surface of a point cloud representing an anatomical volume, by projecting another point P, which corresponds to a location on an anatomical surface of the anatomical volume, onto the virtual surface. The processor is further configured to define a virtual sphere centered on a virtual line joining P to P? such that P lies on a spherical surface of the virtual sphere, and to expand the point cloud throughout the virtual sphere or exclude the virtual sphere from the point cloud. The processor is further configured to regenerate the virtual surface such that, by virtue of having expanded the point cloud or excluded the virtual sphere, P lies on the virtual surface, and to display the regenerated virtual surface on the display. Other embodiments are also described.Type: GrantFiled: August 31, 2020Date of Patent: September 7, 2021Assignee: Biosense Webster (Israel) Ltd.Inventors: Fady Massarwa, Assaf Cohen

Patent number: 9955920Abstract: A method including acquiring a body cavity image and receiving first and second sets of mapping points from a probe inserted into the cavity. A first registration, having a first cumulative error value, is performed between the first set's mapping points and the image, each of the first set's mapping points having a respective first point error value, and a 3D anatomical map is generated including the first set's mapping points whose respective first point error values are less than a specified threshold. A second registration is performed between the received mapping points and the image, each of the received mapping points having a respective second point error value, the second registration having a second cumulative error value lower than the first cumulative error value, and an updated 3D anatomical map is generated including the received mapping points whose respective second point error values are less than the specified threshold.Type: GrantFiled: December 23, 2016Date of Patent: May 1, 2018Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Sharona Ben Shushan, Asaf Merschon, Fady Massarwa
