Abstract

A surgical image capture and display system includes a handheld image capture and pointing device and a display assembly. An image is captured by an image sensor of the handheld device and displayed on the display assembly. The image sensor detects light emitted by one or more beacons of the display assembly. The system determines, based on the light emitted by the one or more beacons, a position or orientation of the handheld device relative to the display assembly. The system updates display of a graphical user interface comprising the image on the display assembly in accordance with the determined position or orientation of the handheld device.

First claim

The invention claimed is:

1 . A surgical image capture and display system, comprising:
a handheld image capture and pointing device, the handheld device comprising an image sensor configured to detect white light and infrared light; a display assembly configured to display one or more images captured by the handheld device; and one or more processors configured to cause the system to:
capture, by the image sensor of the handheld device, an image;
display, by a display of the display assembly, a graphical user interface comprising the image;
while the graphical user interface is displayed by the display, detect, by the image sensor, light emitted by one or more beacons of the display assembly;
determine, based on the light emitted by the one or more beacons of the display assembly, a position or orientation of the handheld device relative to the display assembly, wherein determining the position or orientation comprises determining a location on the display at which the handheld device is aimed; and
update display of the graphical user interface comprising the image in accordance with the position or orientation of the handheld device.

2 . The system of claim 1 , wherein determining the position or orientation comprises determining a distance from the display assembly to the handheld device.

3 . The system of claim 1 , wherein determining the position or orientation comprises determining an offset angle of the handheld device with respect to a plane intersecting the display assembly at a right angle along a line from the top center of the display assembly to the bottom center of the display assembly.

4 . The system of claim 1 , wherein determining the position or orientation comprises determining both the position and the orientation of the handheld device.

5 . The system of claim 1 , wherein determining the orientation comprises determining a rotational orientation of the handheld device with respect to a line along which the handheld device is aimed.

6 . The system of claim 1 , wherein capturing the image is performed prior to detecting the light emitted by the one or more beacons.

7 . The system of claim 1 , wherein:
the system is configured to operate in an image capture mode in which the image is captured and stored by the system; and the system is configured to operate in an image manipulation mode in which the image is displayed on the display and the graphical user interface accepts one or more inputs for manipulation of the image, wherein the one or more inputs are executed via the handheld device and based at least in part on the determined position or orientation of the handheld device.

8 . The system of claim 1 , wherein updating the graphical user interface comprises displaying a cursor on the graphical user interface at a location on the display at which the handheld device is determined to be aimed.

9 . The system of claim 1 , wherein updating the graphical user interface comprises generating and displaying an annotation on the displayed image at a location on the display at which the handheld device is determined to be aimed.

10 . The system of claim 1 , wherein updating the graphical user interface comprises rotating an image annotation in accordance with the orientation of the handheld device.

11 . The system of claim 1 , wherein updating the graphical user interface comprises modifying a zoom level at which the image is displayed in accordance with the position or orientation of the handheld device.

12 . The system of claim 1 , wherein updating the graphical user interface comprises modifying a size of an image annotation in accordance with the position or orientation of the handheld device.

13 . The system of claim 1 , wherein updating the graphical user interface comprises setting a font size for the graphical user interface in accordance with the position or orientation of the handheld device.

14 . The system of claim 1 , wherein updating the graphical user interface comprises displaying a notification based on an offset angle determined in accordance with the determined position or orientation of the handheld device.

15 . The system of claim 1 , wherein the one or more processors are configured to cause the system to:
in accordance with the determined position or orientation of the handheld device, identify a first region of interest of the image; and
apply one or more of a tracking algorithm and an image analysis algorithm to the first region of interest of the image.

16 . The system of claim 15 , wherein:
the image is captured by the image capture and pointing device in a first spectrum; and the one or more processors are configured to cause the system to: capture, by the image capture and pointing device, a second image in a second spectrum; and apply one or more of the tracking algorithm and the image analysis algorithm to a second region of interest corresponding to the first region of interest, wherein the second region of interest is in the second image.

17 . The system of claim 1 , wherein determining the position or orientation of the handheld device is further based on data received from a sensor onboard the handheld device, wherein the sensor comprises one or more of an accelerometer, a gyroscope, and a compass.

18 . The system of claim 1 , wherein determining the position or orientation of the handheld device is further based on processing video frames captured by the image sensor.

19 . The system of claim 18 , wherein processing video frames comprises applying an optical flow algorithm to track a direction of movement in the video frames.

20 . The system of claim 1 , wherein the image is captured by the image sensor as part of a time-series of video frames.

21 . The system of claim 1 , wherein the image is one of a white-light image and a fluorescence image.

22 . The system of claim 1 , wherein detecting the light emitted by the one or more beacons of the display assembly is performed by the image sensor of the handheld device.

23 . The system of claim 1 , wherein the light emitted by the one or more beacons is infrared light.

24 . The system of claim 1 , wherein the one or more beacons are positioned proximate to a periphery of the display in respective fixed locations relative to the display.

25 . A non-transitory computer-readable storage medium for surgical image capture and display, the non-transitory computer-readable storage medium storing instructions configured to be executed by one or more processors of a surgical image capture and display system comprising (a) a handheld image capture and pointing device, the handheld device comprising an image sensor configured to detect white light and infrared light and (b) a display assembly configured to display one or more images captured by the handheld device, wherein executing the instructions causes the system to:
capture, by the image sensor of the handheld device, an image; display, by a display of the display assembly, a graphical user interface comprising the image; while the graphical user interface is displayed by the display, detect, by the image sensor, light emitted by one or more beacons of the display assembly; determine, based on the light emitted by the one or more beacons of the display assembly, a position or orientation of the handheld device relative to the display assembly, wherein determining the position or orientation comprises determining
