Abstract:
1. A method, comprising: constructing a surface of a body cavity from image data obtained from a medical imaging system; pressing a distal end of a probe against a wall of the body cavity; while pressing the distal end against the wall, accepting, from the probe, position measurements indicating a position of the probe within the body cavity, physiological property measurements indicating a physiological property of the body cavity and force measurements indicating a force between the distal end and the wall; generating an anatomical map of the body cavity using the position measurements and the physiological property measurements; combining the surface and the anatomical map by laying the anatomical map over the surface; distorting the shape of the surface at the position indicated by the position measurements by incorporating a three dimensional effect on the surface, so as to form a distorted surface, upon detecting that the force measurements exceed a predefined amount; and displaying the combined distorted surface and the anatomical map, the three dimensional effect being a visual indicator of the amount of force caused by the pressing.
