SYSTEM AND METHOD OF OVERLAYING IMAGES OF DIFFERENT MODALITIES
First Claim
1. A method overlaying a three-dimensional image of a tissue and an image of the tissue from an imaging transducer, having a field of view, the method comprising:
- co-registering a first co-ordinate space of the three-dimensional image with a second co-ordinate space of the field of view of the image from the imaging transducer;
determining pixel dimensions of the field of view in the second co-ordinate space;
scaling the three-dimensional image in the first co-ordinate space to match the pixel dimensions of the field of view in the second co-ordinate space;
transforming position and orientation of the three-dimensional image of the tissue in the first co-ordinate space to match position and orientation of the field of view in the second co-ordinate space; and
displaying an overlaid image comprising the three-dimensional image and the field of view of the imaging transducer.
