Systems and methods for surgical navigation
Disclosed are systems, methods, and techniques for registering a HMD coordinate system of a head-mounted display (HMD) and a localizer coordinate system of a surgical navigation localizer. A camera of the HMD captures at least one image of a registration device having a registration coordinate system and a plurality of registration markers. The registration markers are analyzed in the at least one image to determine a pose of the HMD coordinate system relative to the registration coordinate system. One or more position sensors comprised in the localizer detect a plurality of tracking markers comprised in the registration device to determine a pose of the registration coordinate system relative to the localizer coordinate system. The HMD coordinate system and the localizer coordinate system are registered using the registration device, wherein positions of the registration markers are known with respect to positions of the tracking markers in the registration coordinate system.
Method and system for hand tracking in a robotic system
A method and system for hand tracking in a robotic system includes a hand tracking system and a controller coupled to the hand tracking system. The controller is configured to receive, from the hand tracking system, a plurality of locations of a hand; determine if the hand is in a first hand pose based on the plurality of locations; in response to determining that the hand is in the first hand pose, and switch the robotic system to a hand trajectory detection mode. While in the hand trajectory detection mode, the control unit is configured to detect, based on hand tracking information from the hand tracking system, that the hand has performed a first hand trajectory of a plurality of known hand trajectories; and in response to detecting the first hand trajectory, change a mode of operation of the robotic system.
System and method for local three dimensional volume reconstruction using a standard fluoroscope
A system and method for constructing fluoroscopic-based three dimensional volumetric data from two dimensional fluoroscopic images including a computing device configured to facilitate navigation of a medical device to a target area within a patient and a fluoroscopic imaging device configured to acquire a fluoroscopic video of the target area about a plurality of angles relative to the target area. The computing device is configured to determine a pose of the fluoroscopic imaging device for each frame of the fluoroscopic video and to construct fluoroscopic-based three dimensional volumetric data of the target area in which soft tissue objects are visible using a fast iterative three dimensional construction algorithm.

System and method for tracking completeness of co-registered medical image data
A system and method for tracking completeness of co-registered medical image data is disclosed herein. The system and method tracks the position of an anatomical reference marker positionable on a patient and an ultrasound probe during an imaging session and co-registers medical images based on positional data received from the anatomical reference marker and the ultrasound probe. Using the co-registered image data, the system and method generates a surface contour of a region of interest (ROI) of the patient, such as a breast. The surface contour is defined to represent an interface between a chest wall structure and tissue of the ROI in a plurality of co-registered medical images. A completeness map of the image data within the defined surface contour during the imaging session is generated and overlaid on a graphic representation of the ROI.
Distance indication for invasive microsurgical instruments
A microsurgical instrument having one or more distance indication members is provided. In a particular embodiment, the microsurgical instrument comprises a microsurgical tool and a first distance indication member coupled to, and extending beyond a distal end of, the microsurgical tool. A distal portion of the first distance indication member may be configured to deflect when in contact with a tissue surface, without causing damage to the tissue surface, to give a visual indication that the distal end of the microsurgical tool is in proximity to the tissue surface. The distal portion of the distance indication member can be further configured to return to a non-deflected configuration when no longer in contact with the tissue surface.
Skin 3D model for medical procedure
The present disclosure provides a method of medical procedure using augmented reality for superimposing a patient's medical images (e.g., CT or MRI) over a real-time camera view of the patient. Prior to the medical procedure, the patient's medical images are processed to generate a 3D model that represents a skin contour of the patient's body. The 3D model is further processed to generate a skin marker that comprises only selected portions of the 3D model. At the time of the medical procedure, 3D images of the patient's body are captured using a camera, which are then registered with the skin marker. Then, the patient's medical images can be superimposed over the real-time camera view that is presented to the person performing the medical procedure.
Systems and methods for ablation visualization
The visualization method includes displaying three-dimensional image data of at least one anatomical feature of a patient, receiving user input of the target for placing an ablation needle in the at least one anatomical feature of the patient, determining the position and orientation of the ablation needle based on the user input, displaying an image of a virtual ablation needle in the three-dimensional image data of the at least one anatomical feature of the patient according to the determined position and orientation, receiving user input of parameters of operating the ablation needle, and displaying a three-dimensional representation of the result of operating the ablation needle according to the input parameters.
Real-time methods for magnetic resonance spectra acquisition
The invention pertains to advances in real-time methods in nuclear magnetic resonance by offering a new dual-frequency dynamic nuclear polarization (DNP) method that uses a microwave beam to polarize the spins of electrons and concomitantly act as a NMR transmitter.
