Abstract
Embodiments disclose a real-time surgery method and apparatus for displaying a stereoscopic augmented view of a patient from a static or dynamic viewpoint of the surgeon, which employs real-time three-dimensional surface reconstruction for preoperative and intraoperative image registration. Stereoscopic cameras provide real-time images of the scene including the patient. A stereoscopic video display is used by the surgeon, who sees a graphical representation of the preoperative or intraoperative images blended with the video images in a stereoscopic manner through a see-through display.
Claims30
A system comprising:
- a stereoscopic optical see-through head mounted display;
- at least one computing system;
- and
- at least one camera, at least one 3D scanner, or at least one camera and at least one 3D scanner,
- wherein the at least one computing system is configured to track at least a portion of a physical instrument, at least a portion of a physical device, at least a portion of a physical spine of a patient or a combination thereof using the at least one camera, the at least one 3D scanner, or the at least one camera and the at least one 3D scanner,
- wherein the at least one computing system is configured to generate at least one three-dimensional (3D) surface representation of at least a portion of a surgical guide, at least a portion of the tracked physical instrument, at least a portion of the tracked physical device, at least a portion of the tracked physical spine, at least a portion of an anatomical model, at least a portion of an image information of the tracked physical spine, or a combination thereof;
- wherein the at least one computing system is configured to generate a 3D stereoscopic view, displayed by the stereoscopic optical see-through head mounted display, the 3D stereoscopic view comprising the at least one 3D surface representation,
- wherein the at least one computing system is configured to superimpose the 3D stereoscopic view on a target portion of the physical spine,
- wherein the system is configured to adjust in real time the 3D stereoscopic view responsive to movement of the stereoscopic optical see-through head mounted display,
- wherein the system is configured to adjust in real time the 3D stereoscopic view responsive to movement of the physical spine from a first position to a second position, and
- wherein the first and second positions of the physical spine of the patient are different.
