Abstract

Claims (14)

1. A method for performing a surgical procedure on a patient, comprising:

generating a three-dimensional model of a portion of the body of the patient; and

guiding a surgical instrument within the body of the patient based on the model and real-time feedback obtained by monitoring the surgical procedure using fluoroscopy,

wherein generating the three-dimensional model comprises determining obstacles in the path of the surgical procedure by modeling light rays from a surgical target to a region of surgical access on the skin of the patient.

2. The method of claim 1 , wherein said determining obstacles in the path of the surgical procedure comprises receiving information regarding the surgical procedure.

3. The method of claim 2 , wherein, in said receiving information regarding the surgical procedure, the information includes information regarding a surgical target to be operated upon, a region of access on the skin of the patient, and a surgical instrument to be used during the surgical procedure.

4. The method of claim 1 , wherein said generating the three-dimensional model comprises:

receiving an intra-operative CT scan image;

generating a three-dimensional isotropic scaffold based on the intra-operative CT scan image; and

fusing one or more images with the three-dimensional isotropic scaffold.

5. The method of claim 4 , further comprising fusing the three-dimensional isotropic scaffold with at least one non-intra-operative CT image selected from the group consisting of a pre-operative CT image, a pre-operative MRI image, a pre-operative ultrasound image, a pre-operative SPECT image, a pre-operative PET image, and an intra-operative ultrasound image.

6. The method of claim 4 , wherein the three-dimensional isotropic scaffold comprises isotropic voxels.

7. The method of claim 4 , wherein said fusing of said one or more images with the three-dimensional isotropic scaffold reduces distortions.

8. The method of claim 4 , wherein said fusing of said one or more images with the three-dimensional isotropic scaffold creates a multi-modality anatomic model.
