SYSTEM AND METHOD TO POSITION A TRACKING SYSTEM FIELD-OF-VIEW
A method and system are provided to assist in positioning the field-of-view (FOV) of an optical tracking system during a computer-assisted surgical procedure. The method includes displaying a view from a visible light detector on a display, and generating an outline as an overlay on the display of a FOV of two or more optical tracking detectors on the displayed view from the visible light detector. A user then positions at least one of: a) the two or more optical tracking detectors, or b) a tracked object based on the displayed view from the visible light detector and the generated outline.
1 . A method to assist in positioning one or more optical detectors of an optical tracking system, said method comprising:
displaying a view from a visible light detector on a display; and
displaying a first field-of-view (FOV) of the one or more optical detectors on the displayed view.
2 . The method of claim 1 wherein the first FOV of the one or more optical detectors is an outline overlaid on the displayed view.
3 . The method of claim 1 wherein said one or more optical detectors are configured to detect infrared light.
4 . The method of claim 1 wherein said visible light detector is in a fixed position relative to said one or more optical detectors.
5 . The method of claim 2 wherein the outline comprises bounded geometrical shape, a semi-translucent shaded region, or a bounded region filled with a gradient pattern.
6 . The method of claim 1 further comprising displaying a marking indicating a center of the first FOV of the one or more optical tracking detectors on the displayed view.
7 . (canceled)
8 . The method of claim 21 further comprising displaying two or more fields-of-view (FOVs) of said two or more optical detectors on the displayed view, wherein each of said two or more FOVs correspond to a second FOV of said two or more optical detectors when tracking an object.
9 . The method of claim 8 further comprising automatically updating each of said two or more FOVs based on a distance of the object relative to the two or more optical detectors.
10 . (canceled)
11 . The method claim 8 wherein each of said two or more FOVs are displayed as on outline of the second FOV of the two or more optical detectors.
12 . The method of claim 8 wherein each of said two or more FOVs are differentiated from one another by at least one of: an indicia, a color, or a label.
13 . The method of claim 1 further comprising displaying a position of fiducial markers in the first FOV on the displayed view.
14 . The method of claim 3 wherein said optical detector is a camera.
15 . (canceled)
16 . A system, comprising:
an optical tracking system comprising one or more optical detectors;
a visible light detector in a fixed position with respect to the or more optical detectors; and
one or more processors executing software, wherein said software when executed by the processor
displays a first field-of-view (FOV) of said one or more optical detectors on a displayed view from the visible light detector.
17 . (canceled)
18 . The system of claim 16 wherein said one or more optical detectors are configured to detect infrared light.
19 . The system of claim 16 further comprising a hand-held surgical device or a surgical robot.
20 . The system of claim 16 wherein the software when executed by the one or more processors displays a marking on the displayed view, wherein the marking indicates a center of the first FOV of said one or more optical detectors.
21 . The method of claim 1 wherein the optical tracking system comprises two or more optical detectors.
22 . The system of claim 16 wherein the FOV of said optical detector is displayed as an outline of said one or more optical detectors overlaid on the displayed view.
23 . The system of claim 16 wherein the optical tracking system comprises two or more optical detectors.
24 . The system of claim 16 wherein the optical tracking system comprises the one or more processors and software.
