Method and system for generating three-dimensional model of part of a body from fluoroscopy image data and specific landmarks
First Claim
1. A method for generating a three-dimensional model of a part of the body with the aid of a medical navigation system, comprising:
- identifying to the navigation system landmarks on the part of the body that are characteristic of the model of the part of the body;
obtaining at least two fluoroscopy image data sets for each of one or more predetermined, individual and delimited regions of the part of the body;
ascertaining characteristic body part data by processing and combining the landmark positions and parameters of the fluoroscopy data sets; and
generating a three-dimensional and positionally determined model of the part of the body from the characteristic body part data.

Abstract
A method for generating a three-dimensional model of a part of the body with the aid of a medical and/or surgical navigation system, comprising the steps of identifying to the navigation system landmarks on the part of the body that are characteristic of the model of the part of the body; obtaining at least two fluoroscopy image data sets for each of one or more predetermined, individual and delimited regions of the part of the body; ascertaining characteristic body part data by processing and combining the landmark positions and parameters of the fluoroscopy data sets; and generating a three-dimensional and positionally determined model of the part of the body from the characteristic body part data.

16. A system for generating a three-dimensional model of a part of the body with the aid of a medical navigation system, comprising:
-
a processor circuit having a processor and a memory;
a model generation subsystem stored in the memory and executable by the processor, the subsystem comprising;
logic that directs the identification to the navigation system landmarks on the part of the body that are characteristic of the model of the part of the body;
logic that obtains at least two fluoroscopy image data sets for each of one or more predetermined, individual and delimited regions of the part of the body;
logic that ascertains characteristic body part data by processing and combining the landmark positions and parameters of the fluoroscopy data sets; and
logic that generates a three-dimensional and positionally determined model of the part of the body from the characteristic body part data.

17. A program embodied in a computer-readable medium for generating a three-dimensional model of a part of the body with the aid of a medical navigation system, comprising:
-
code that directs the identification to the navigation system landmarks on the part of the body that are characteristic of the model of the part of the body;
code that obtains at least two fluoroscopy image data sets for each of one or more predetermined, individual and delimited regions of the part of the body;
code that ascertains characteristic body part data by processing and combining the landmark positions and parameters of the fluoroscopy data sets; and
code that generates a three-dimensional and positionally determined model of the part of the body from the characteristic body part data.
