  • Publication number: 20240020831
    Abstract: System and method of registering a medical image of a patient in an imaging space to the patient in a physical space preferably without the use of any embedded radiopaque fiducials in medical images is provided. In one way, intra-op 2D medical images are used to register a pre-op unregistered 3D medical image. The 2D medical images are registered based on simultaneous tracking of the tracking markers on the imaging device and on the patient by a tracking device at the time of image capture. The 2D images are matched to corresponding simulated 2D images generated from the pre-op 3D image volume. Thus, registration of a pre-op 3D image to the patient is accomplished without performing another 3D scan of the patient.

  • Patent number: 11850012
    Abstract: A system for robotic surgery makes use of an end-effector which has been configured so that any selected one of a group of surgical tools may be selectively connected to such end-effector. The end-effector makes use of a tool-insert locking mechanism which secures a selected one of the surgical tools at not only a respective, predetermined height and angle of orientation, but also at a rotational position relative to an anatomical feature of the patient. The tool-insert locking mechanism may include interchangeable inserts to interconnect multiple tools to the same end-effector. In this way, different robotic operations may be accomplished with less reconfiguration of the end-effector. The end-effector may also include a tool stop which has a sensor associated with a moveable stop mechanism which may be positioned to selectively inhibit tool insertion or end-effector movement.

  • Publication number: 20230397956
    Abstract: A surgical implant planning computer is connectable to a fluoroscopy imager, a marker tracking camera, and a robot having a robot base coupled to a robot arm that is movable by motors relative to the robot base. Operations include performing a registration setup mode that determines occurrence of a first condition indicating the marker tracking camera can observe to track reflective markers that are on a fluoroscopy registration fixture of the fluoroscopy imager, and determines occurrence of a second condition indicating the marker tracking camera can observe to track dynamic reference base markers attached to the robot arm and/or an end-effector connected to the robot arm. While both of the first and second conditions occur, operations are allowed to be performed to obtain a first intra-operative fluoroscopic image of a patient along a first plane and to obtain a second intra-operative fluoroscopic image of the patient along a second plane that is orthogonal to the first plane.

  • Patent number: 11819283
    Abstract: A surgical implant planning computer positions an implant device relative to a bone of a patient. An initial image of a bone is obtained. An initial location data structure is obtained that contains data defining mapping between locations on the implant device and corresponding locations relative to the bone in the initial image. A target image of the bone of the patient is obtained. A transformation matrix is generated that transforms a contour of a portion of the bone in the initial image to satisfy a defined rule for conforming to a contour of a corresponding portion of the bone in the target image. A transformed location data structure is generated based on applying the transformation matrix to the initial location data structure. A graphical representation of the implant device is displayed overlaid at locations on the target image of the bone determined based on the transformed location data structure.

  • Patent number: 11806084
    Abstract: Embodiments consistent with the present disclosure allow the ring, arc, and linear offset values for a stereotactic frame to be determined for a cranial procedure without requiring a CT scan to be acquired with the fiducial frame attached. Having the ring, arc, and offset values available for a cranial procedure allows the surgeon to revert to traditional stereotactic ring-arc frame guidance as a fallback strategy in case a robot cannot be used. This disclosure also provides an alternate method for registering a ring-arc system to the medical image volume for facilities having no CT scanner or scanner with limited field of view such that the intended fiducial localizer cannot be used.

  • Publication number: 20230310086
    Abstract: A camera tracking system for computer assisted navigation during surgery. Operations identify stray markers in a frame of tracking data from tracking cameras, and identify stray markers of a reference array. Stray markers of the reference array are designated assigned status and, otherwise, designated unknown status. The operations designate other of the assigned status stray markers and any of the unknown status stray markers along a same epipolar line of the tracking cameras as one of the assigned status stray markers as being epipolar ambiguous status. For each one of the epipolar ambiguous status stray markers, the operations estimate 3D locations where phantom markers can appear in the frame based on epipolar ambiguity of the tracking cameras when determining location of the one of the epipolar ambiguous status stray markers. The operations designate the unknown status stray markers within a threshold distance of the estimated 3D locations of phantom markers as being phantom status.

  • Publication number: 20230304396
    Abstract: Systems and methods described herein provide for the estimation of the maximum reservoir pressure at which fluid can be injected into a reservoir before causing conductivity increase due to fracture/fault reactivation. An exemplary method includes computing the maximum reservoir pressure for the location of interest prior to fracture/fault reactivation at a given depleted reservoir pressure based on a computed probability of non-exceedance for a field or laboratory estimate of the maximum reservoir pressure prior to fracture/fault reactivation and a computed pressure distribution including a range of potential maximum reservoir pressures for the location of interest prior to fracture/fault reactivation at the given depleted reservoir pressure. The method also includes outputting the computed maximum reservoir pressure as the estimated maximum reservoir pressure for performing a fluid injection operation for the location of interest.
