Abstract
Disclosed herein is a method of graphically presenting an indicating marker over a 3-D model of a tissue surface during a catheterization procedure, comprising determining a region over the 3-D model, deforming the indicating marker to congruently match a shape defined by the 3-D model across the region at a plurality of positions; and rendering the 3-D model into an image including the deformed indicating marker by generating an image of the 3-D model covered by said deformed indicating marker.
Claims21
A method of visually rendering a 3-D model of a tissue region to indicate a position and a facing direction of a catheter probe during a catheterization procedure, the method comprising:
- determining said position and facing direction of a distal end of said catheter probe with respect to said tissue region;
- and
- rendering said 3-D model to include a simulation of a first indicating mark, said first indicating mark being simulated in a position of a surface portion defined by said 3-D model, wherein the position is also located along an axis extending distally from said determined position and in said determined facing direction of said distal end of said catheter.
Apparatus for visually rendering a 3-D model of a tissue region to indicate a position and a facing direction of a catheter probe during a catheterization procedure, the apparatus comprising:
- a non-transitory computer readable medium storing program instructions;
- at least one hardware processor in communication with said non-transitory computer readable medium, that when said instructions are executed by said at least one hardware processor, said execution causes said at least one hardware processor to:
- (a) determine said position and facing direction of a distal end of said catheter probe with respect to said tissue region;
- and
- (b) render said 3-D model to include a simulation of a first indicating mark, said first indicating mark being simulated in a position of a surface portion defined by said 3-D model, wherein the position is also located along an axis extending distally from said determined position and in said determined facing direction of said distal end of said catheter.
