Abstract: Systems and methods for registering one or more anatomical elements are provided. The system may comprise an imaging device and a navigation system configured to track a pose of a marker coupled to an object and configured to identify the marker. A first image may be received from a surgical plan. Pose information describing the pose of the marker and a marker identification of the marker may be obtained from the navigation system. An object identification based on the marker identification may be retrieved from a database. Image data of a second image depicting an anatomical element and the object may be obtained from the imaging device. The image data, the pose information, and the object identification may be input into a registration model. The registration model may be configured to register the anatomical element to the first image based on the pose information and the object identification.

Abstract: A robotic registration kit according to at least one embodiment of the present disclosure includes an elongate arm (304) extending from a proximal end (302) to a distal end (306) including a target receiving surface (308) and a robot mount bracket (312) including a robot attachment surface (358), a clamp screw (316), including a bracket contact surface in contact with the robot mount bracket (312) and a threaded outer surface (322), rotationally attached to the robot mount bracket (312) allowing the clamp screw (316) to rotate and preventing axial movement of the clamp screw (316), and a clamp (320) including a plate (324) with a threaded hole (328) running therethrough and a finger (332) extending a distance to a clamp end including a hook portion (336) disposed proximally past the robot attachment surface (358) of the robot mount bracket (312). The clamp (320) is moveable between a clamped state and an unclamped state by a rotational movement of the clamp screw (316) relative to the clamp (320).

Abstract: A robotic surgical system comprising at least two robotic arms having co-ordinate systems known relative to each other, one of the arms carrying an X-ray source, and the other an imaging detector plate. The arms are disposed to enable an image to be generated on the region of interest of a subject. One of the arms can additionally or alternatively carry a surgical tool or tool holder, such that the pose of the tool is known in the same co-ordinate system as that of an image generated by the X-ray source and detector. Consequently, any surgical procedure planned on such an X-ray image can be executed by the tool with high accuracy, since the tool position is known in the image frame of reference. This enables the surgeon to accurately position his tool in a real-time image without the need for an external registration procedure.

Abstract: Systems, methods, and devices for capturing a single image with multiple exposures is provided. An imaging device may be provided comprising a source configured to emit a wave for a time period and a detector configured to receive a signal indicative of the wave. A wave may be emitted for a time period and a signal may be received indicative of the emitted wave. A first image dataset may be saved with a first timestamp referencing a first time within the time period. A second image dataset may be saved with a second timestamp referencing a second time within the time period. The second time may occur after the first time.

Abstract: A system and method for generating a corrected image is provided. A plurality of poses for an imaging device may be calculated based on information about an object within a patient's anatomy. An image may be received from the imaging device at each pose of the plurality of poses to yield an image set. Each image may depict at least a portion of an anatomical element of the patient and an object. A set of saturated areas in which the object has caused saturated attenuation, and a set of unsaturated areas in which the object has not caused saturated attenuation may be identified in the images of the image set. A corrected image may be generated by combining data from the set of unsaturated areas, the corrected image depicting the anatomical feature with fewer than all of the saturated areas in the set of saturated areas.

Abstract: Systems and methods for generating multiple registrations is provided. An image depicting a portion of a patient's anatomy and a tracking device affixed to an accurate robot may be received. A first registration of a patient coordinate space to a robotic coordinate space may be generated based on the image. A second registration of the patient coordinate space to a navigation coordinate space based at least in part on a position of second markers on the tracking device detected by a navigation system may be generated. The first registration and the second registration may be independent of each other.

Abstract: Methods and systems for providing a safety mechanism for a robotically controlled surgical tool. Embodiments of the methods use sensors to detect parameters that vary by the tissue traversed by a surgical tool. The sensors detect signals arising from the interaction of the surgical tool with the tissue and provide this information to a robotic controller. For example, during drilling, the sensors may measure power, vibration, sound frequency, mechanical load, electrical impedance, and distance traversed according to preoperative measurements on a three-dimensional image set used for planning the tool trajectory. By comparing the detected output with that expected for the tool position based on the planned trajectory, identified discrepancies in output would indicate that the tool has veered from the planned trajectory. The robotic controller may then alter the tool trajectory, change the speed of the tool, or discontinue power to the tool, thereby preventing damage to underlying tissue.

Abstract: Registering a robotic coordinate system defined by a robotic system and a navigation coordinate system defined by a tracking system localizer. The registration includes: determining a robotic coordinate system between a first portion of the robotic system and a subject separate from the first portion of the robotic system; connecting a fiducial marker at a first known position relative to the robotic coordinate system and relative to the first portion of the robotic system; acquiring a fiducial image at an initial time with an imaging system of the fiducial marker; detecting the acquisition of the fiducial image with the imaging system at the initial time with a detector; and sending a command to determine or record an initial position of at least one of the first portion of the robotic system or the robotic coordinate system at the initial time.
