Abstract
An imaging platform system that provides integrated navigation capabilities for surgical guidance. The system can include two robotic arm systems, one robotic arm system holding an imaging source, and the other holding an imaging sensor. These robotic arm systems are able to move and provide three-dimensional tomographic scans, static radiographic images, and dynamic fluoroscopic image sequences. A third robotic arm system can be included in the imaging platform system as a surgeon guided tool-holder to accurately implement an image-guided surgical plan. The robotic systems can manipulate imaging and surgical components into and out of the operative field as needed, enhancing the choreography between a surgical team and assistive technology. A handle can be included as part of a manual positioning control subsystem. The handle can be mounted to an imaging robotic system above and/or below an operating table, and also can be mounted to a tool-holding robotic system.

11. A method of generating a scout view image for an image-guided surgical procedure, the method comprising:
-
(a) in a non-radiographic imaging mode, manually positioning one of an X-ray source and an X-ray sensor mounted on a first robotic arm so as to designate a beginning point of a desired anteroposterior (AP) radiograph, the other of the X-ray source and the X-ray sensor being mounted on a second robotic arm; (b) in the non-radiographic imaging mode, manually positioning said one of the X-ray source and the X-ray sensor mounted on the first robotic arm so as to designate an ending point of the desired AP radiograph; (c) receiving at a control system the designated beginning point and the designated end point; (d) by the control system, calculating respective radiographic imaging paths for the X-ray source and the X-ray sensor; (e) by the control system, controlling the first and second robotic arms to follow the calculated radiographic imaging paths from the designated beginning point to the designated end point while imaging using the X-ray source and the X-ray sensor; (f) by the control system, generating a contiguous X-ray image scan based on signals from the X-ray sensor obtained during (e); (g) by the control system, displaying the X-ray image scan on a computer screen; (h) manually positioning a marker mounted on a third robotic arm to designate a spatial point; and (i) by the control system, while controlling the third robotic arm to hold the marker in place at the spatial point, repeating (e) so as to generate a confirmatory radiograph. - View Dependent Claims (18)
