STEERABLE ENDOSCOPE SYSTEM WITH AUGMENTED VIEW
A steerable endoscope system is provided with an augmented view. An augmented reality display includes a rendered model of an anatomical structure corresponding to a patient anatomy pinned in the field of view, an endoscope marker moving through the virtual model, and an image from an endoscope at a location within the patient anatomy.
1 . A computer-controlled medical-scope system, comprising:
a medical scope comprising a steerable distal tip with a camera that produces an image signal and an orientation sensor that produces an orientation signal;
a first display comprising a hardware screen that depicts images from the image signal; and
a second display comprising an augmented reality visualization, wherein the augmented reality visualization comprises a composite view of computer-generated graphics overlaid on a real-world field of view, wherein the computer-generated graphics comprise:
an anatomical model;
a scope marker positioned in the anatomical model according to the orientation signal;
a first illumination depicting a real-time direction of view of the camera; and
a second illumination depicting where the medical scope has previously traveled.
2 . The computer-controlled medical-scope system of claim 1 , wherein the computer-generated graphics further comprise the images from the image signal.
3 . The computer-controlled medical-scope system of claim 1 , wherein the hardware screen comprises a touch screen.
4 . The computer-controlled medical-scope system of claim 1 , further comprising a controller in wired or wireless communication with the medical scope and comprising a hardware memory storing instructions for:
receiving the orientation signal; and
moving the scope marker within the anatomical model according to the orientation signal.
5 . The computer-controlled medical-scope system of claim 4 , wherein the controller comprises an augmented reality controller in wireless communication with an augmented reality viewer providing the augmented reality visualization.
6 . The computer-controlled medical-scope system of claim 1 , further comprising a medical-scope controller comprising a handle connected to the medical scope, wherein the first display is mounted to the handle, and wherein the medical-scope controller relays the image signal and the orientation signal to the augmented reality controller.
7 . A computer-implemented method for generating an augmented reality display over a field of view, comprising:
receiving, at a controller, a position signal from a medical scope, the position signal comprising position, orientation, or movement data of a steerable distal end of the medical scope;
receiving, at the controller, sensor signals from one or more sensors of the medical scope, the sensor signals comprising real-time data including a two-dimensional (2D) camera image associated with a current position of the medical scope;
rendering, at the controller, virtual objects comprising:
a three-dimensional anatomical model registered to a real object in the field of view;
a scope marker positioned within the anatomical model at the current position of the medical scope; and
a three-dimensional image portion, based on the 2D camera image, mapped onto the three-dimensional anatomical model in front of the scope marker; and
displaying the virtual objects through a head-mounted viewer.
8 . The computer-implemented method of claim 7 , further comprising updating the virtual objects according to the position signal and the 2D camera image from the one or more sensors of the medical scope.
9 . The computer-implemented method of claim 8 , wherein updating the virtual objects comprises moving the scope marker and the three-dimensional image portion within the anatomical model along with movement of the medical scope.
10 . The computer-implemented method of claim 7 , wherein the scope marker comprises a tubular body and a camera frustum.
11 . A computer-controlled medical scope system, comprising:
a medical scope comprising:
a steerable distal tip comprising:
a camera that produces an image signal; and
an orientation sensor that produces an orientation signal;
a medical-scope controller having a display comprising a hardware screen that depicts images from the image signal; and
an augmented reality viewer that generates an augmented reality visualization comprising a composite view of computer-generated graphics overlaid on a real-world field of view, wherein the computer-generated graphics comprise:
an anatomical model;
a scope marker positioned in the anatomical model according to the orientation signal;
a first illumination depicting a real-time direction of view of the camera; and
a second illumination to indicate where the medical scope has previously traveled.
12 . The system of claim 11 , wherein the computer-generated graphics further comprise the images from the image signal.
13 . The system of claim 11 , wherein the hardware screen comprises a touch screen.
14 . The system of claim 11 , wherein the medical-scope controller further comprises an augmented reality controller in wireless communication with the augmented reality viewer providing the augmented reality display.
15 . The system of claim 14 , wherein the medical-scope controller comprises a handle connected to the medical scope, wherein the display is mounted to the handle, and wherein the medical scope controller relays the image signal and the orientation signal to the augmented reality controller.
16 . The system of claim 11 , wherein the first illumination comprises a first brightest illumination within a frustum region of the camera.
17 . The system of claim 16 , wherein the second illumination comprises a second brightest illumination in a region outside of the camera frustum.
18 . The system of claim 17 , wherein the first brightest illumination and the second brightest illumination are of the same color.
19 . The system of claim 11 , wherein the anatomical model is a model of one or more patient airways.
20 . The system of claim 11 , wherein the augmented reality display further includes a floating window that displays an image based on the image signal.
