Abstract
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.
