Abstract
There is provided a method for intra-operatively presenting an approximate model of an anatomical structure by collecting a cloud of small surfaces. The cloud of small surfaces is gathered with a registration pointer having an adapted tip capable of making contact with the surface of an structure and registering the normal at the point of contact.
Claims39
A method for intra-operatively presenting an approximate model of an anatomical structure, the method comprising:
- applying a registration tool having a position sensing system associated therewith to a plurality of locations on said anatomical structure,
- acquiring input data using said registration tool such that a point is registered for each of said locations;
- processing said input data into an approximate model of said anatomical structure;
- and displaying said approximate model on an output device.
A system for displaying an approximate model of a surface of an anatomical structure, the system comprising:
- a registration tool having a first end adapted for applying to a surface of an anatomical structure;
- a position sensing system associated to said registration tool for acquiring input data representing a plurality of locations on said surface of an anatomical structure such that a position and orientation of said registration tool is determined at each of said plurality of locations;
- a storing module for receiving and storing said input data from said position sensing system;
- a processing module for processing said input data into an approximate model of said anatomical structure;
- and
- an output device for displaying said approximate model of said anatomical structure.
A registration tool for intra-operatively acquiring data representing an approximate model of an anatomical structure, the tool having an adapted tip at a first end such that an anatomical surface and a normal to said anatomical surface are registered when said tip is applied to said anatomical structure.
