Patent Images
1. A method for image-guided surgery, comprising:
- capturing a primary modality image of a real surgical field with a camera system, wherein the camera system includes an endoscope camera to capture at least the primary modality image as an internal image of a patient;
obtaining a secondary modality image of the real surgical field registered to the primary modality image;
tracking a position of the endoscope camera within a body cavity of the patient;
generating a surgical guidance image based at least in part upon the secondary modality image, wherein the surgical guidance image indicates if the secondary modality image ceases to be registered to the primary modality image, by discontinuing the secondary modality image or by providing a separate warning within the surgical guidance image; and
projecting the surgical guidance image from a projector onto the real surgical field of the patient, wherein the surgical guidance image presents visual augmentations directly over one or more anatomical structures in the real surgical field to inform a medical practitioner during a surgical procedure, wherein the surgical guidance image includes a visual indication, projected on or over the patient, of the position of the endoscope camera within the body cavity of the patient, wherein the surgical guidance image is projected with an identification overlay that automatically identifies and labels the one or more anatomical structures based upon registration, by a controller communicatively coupled to the camera system, of the secondary modality image to the primary modality image.

Abstract
Image guided surgery includes capturing a primary modality image of a surgical field of a patient with a camera system, obtaining a secondary modality image of the surgical field registered to the primary image, generating a surgical guidance image based at least in part upon the secondary modality image, and projecting the surgical guidance image onto the patient. The surgical guidance image presents visual augmentations on or over the patient to inform a medical practitioner during a surgical procedure.

13. A surgical guidance system, comprising:
-
a camera system repositionable relative to a patient, wherein the camera system includes an endoscope camera; a tracking system configured to locate and track a position of the endoscope camera within a body cavity of the patient; a projector repositionable relative to the patient; and a controller communicatively coupled to the camera system, the tracking system, and the projector, wherein the controller includes one or more processors and logic that, when executed by the one or more processors cause the surgical guidance system to perform operations including; capturing a primary modality image of a real surgical field of a patient with the camera system, wherein the primary modality image includes as an internal image of the patient; obtaining a secondary modality image of the real surgical field registered to the primary modality image; generating a surgical guidance image based at least in part upon the secondary modality image and the position of the endoscope camera within the body cavity of the patient; and projecting the surgical guidance image from the projector onto the patient, wherein the surgical guidance image indicates, by discontinuing the secondary modality image or by providing a separate warning within the surgical guidance image, if the secondary modality image ceases to be registered to the primary modality image, wherein the surgical guidance image presents visual augmentations over the patient to inform a medical practitioner during a surgical procedure, wherein the surgical guidance image includes a visual indication projected on or over the patient of a location of the endoscope camera within the body cavity of the patient, wherein a position of the visual indication moves within the surgical guidance image based at least in part upon the location of the endoscope camera within the body cavity of the patient. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method for image-guided surgery, comprising:
-
capturing a primary modality image of a real surgical field with a camera system, wherein the camera system includes an endoscope camera to capture at least the primary modality image as an internal image of a patient; obtaining a secondary modality image of the real surgical field registered to the primary modality image; tracking a position of the endoscope camera within a body cavity of the patient; generating a surgical guidance image based at least partially upon the secondary modality image; and projecting the surgical guidance image from a projector onto the real surgical field of the patient, wherein the surgical guidance image presents visual augmentations directly over one or more anatomical structures in the real surgical field to inform a medical practitioner during a surgical procedure, wherein the surgical guidance image includes a visual indication, projected on or over the patient, of a location of the endoscope camera within the body cavity of the patient, wherein the surgical guidance image also includes the internal image from the endoscope camera projected on the real surgical field, wherein a position of the internal image from the endoscope camera moves within the surgical guidance image based at least in part upon the position of the endoscope camera within the body cavity of the patient, and wherein the surgical guidance image is projected with an identification overlay that automatically identifies and labels the one or more anatomical structures based upon registration of the secondary modality image to the primary modality image. - View Dependent Claims (25, 26)
