Abstract

Claims (28)

1. A computer-readable medium having computer-executable instructions stored thereon that, when executed, cause one or more processors to:

direct a dot matrix array of non-visible light beams from a projector onto a surgical site, wherein the dot matrix array is dynamically adaptive and encoded;

produce optical data regarding the surgical site based on light reflected from the surgical site and collected by a camera mounted to a user's headset;

receive user instructions to direct an optical pointer towards physical reference landmarks on physical anatomical reference features of a patient;

construct a three-dimensional model based on the optical data;

produce mapping points by associating annotations provided as the optical pointer lights up the respective physical reference landmarks, wherein the mapping points stabilize images to smooth real-time scanning as the user's headset is moved;

receive user instructions to highlight and inspect respective ones of the anatomical reference features based on the reference landmarks; and

inspect the three-dimensional model of the highlighted anatomical reference features according to received user instructions.

2. The computer-readable medium of claim 1 , wherein the computer-executable instructions further cause the one or more processors to:

fuse the constructed three-dimensional model with an internal three-dimensional model of the surgical site from the viewpoint of the headset, wherein the internal three-dimensional model is derived from a medical imaging process;

register the internal three-dimensional model with the mapping points;

generate an aligned view of the surgical site;

provide the aligned view of the surgical site to the headset; and

update the aligned view of the surgical site in real-time using the mapping points.

3. The computer-readable medium of claim 2 , wherein the updated aligned view of the surgical site is viewable at an unaligned view for the user.

4. The computer-readable medium of claim 1 , wherein the instructions to inspect the anatomical reference features include an instruction to rotate the three-dimensional model of the highlighted anatomical reference features.

5. The computer-readable medium of claim 1 , wherein the instructions to inspect the anatomical reference features include an instruction to divide the three-dimensional model of the highlighted anatomical reference features.

6. The computer-readable medium of claim 1 , wherein the instructions to inspect the anatomical reference features include an instruction to enlarge the size of the three-dimensional model of the highlighted anatomical reference features.

7. The computer-readable medium of claim 1 , wherein the user instructions to inspect the anatomical reference features are received from surgical gloves, worn by the user, having RFID chips inserted therein.

8. The computer-readable medium of claim 7 , wherein the user instructions received from the surgical gloves are based on thumb and forefinger gestures made by the user.

9. The computer-readable medium of claim 1 , wherein the highlighted anatomical reference features include implants for which measurements are stored and retrievable from memory.

10. A computer-readable medium having computer-executable instructions stored thereon that, when executed, cause one or more processors to:

direct a dot matrix array of non-visible light beams from a projector onto a surgical site, wherein the dot matrix array is dynamically adaptive and encoded;

produce optical data regarding the surgical site based on light reflected from the surgical site and collected by a camera mounted to a user's headset;

receive user instructions to direct an optical pointer towards physical reference landmarks on physical anatomical reference features of a patient;

construct a three-dimensional model based on the optical data and radio signals, wherein the radio signals are generated from radio beacons; and

produce mapping points by associating annotations provided as the optical pointer lights up the respective physical reference landmarks, wherein the mapping points stabilize images to smooth real-time scanning as the user's headset is moved.

11. The computer-readable medium of claim 10 , wherein the instructions direct a dot matrix array of non-visible light beams from a projector mounted to a headset onto a surgical site.
