Method for detecting the movement of a temporomandibular joint
11116444 · 2021-09-14 · ·

Described is a method for detecting and displaying the movement of a temporomandibular joint which connects a lower jaw and an upper jaw by magnetic resonance imaging. A marker is secured to the lower jaw, a marker movement curve is generated using magnetic resonance imaging measurement data sets during a first measurement interval, during which the lower jaw is moved relative to the upper jaw, and a point which corresponds to a first position of the lower jaw relative to the upper jaw is ascertained on the movement curve. An image data set is generated during a second measurement interval, during which the temporomandibular joint is not moved, and a first model, which represents at least one part of the upper jaw and/or a temporal bone part that comprises the temporomandibular joint socket, and a second model, which represents at least one part of the lower jaw, are ascertained therefrom. A movement curve of the second model relative to the first model is calculated and displayed using the marker movement curve.

SURGICAL PLANNING SYSTEMS THAT AUTOMATICALLY ASSESS DIFFERENT POTENTIAL TRAJECTORY PATHS AND IDENTIFY CANDIDATE TRAJECTORIES FOR SURGICAL SYSTEMS

Surgical planning systems that automatically identify one or a plurality of different candidate trajectories to a defined intrabody treatment region. The systems can rank the identified candidate trajectories in an order of hierarchy based on defined parameters such as distance from a critical no-go location and whether a single or multiple different candidate trajectories are needed to provide coverage of the defined intrabody treatment region. The surgical planning systems are also configured to provide a User Interface that defines a workflow for an image-guided surgical procedure and allows a user to select one or more of the identified candidate trajectories steps in the workflow.

Fiducial marker for computed tomography and magnetic resonance imaging

Disclosed herein are fiducial markers that include a sealed casing member containing a mixture of iodine and water that includes about 1-300 mg/ml iodine. The fiducial markers may be distinguishable on at least two imaging modalities, such as CT and MRI. The casing member may include a plastic or elastomeric material, such as polyvinyl chloride (PVC) polypropylene, latex, nylon, dynaflex, and may take the form of a length of IV tubing sealed at each of two ends. The length of IV tubing may be crimped to form a desired shape, such as a triangle. Also disclosed are methods of making fiducial markers that are distinguishable on at least two imaging modalities, such as CT and MRI.

In order to provide an apparatus and a method for tracking a movable target (3), in particular tissue (5) which improve the reliability of the target tracking and which reduce the risk of damaging a target, it is intended according to the invention that the at least one applicator (7) is adapted for generating a randomly distributed pattern (13) of markers (11) on the target (3).

SYSTEMS AND METHODS FOR MULTI-MODAL SENSING OF DEPTH IN VISION SYSTEMS FOR AUTOMATED SURGICAL ROBOTS

Systems and methods for multi-modal sensing of three-dimensional position information of the surface of an object are disclosed. In particular, multiple visualization modalities are each used to collect distinctive positional information of a surface of an object. Each of the computed positional information is combined using weighting factors to compute a final, weighted three-dimensional position. In various embodiments, a first depth may be recorded using fiducial markers, a second depth may be recorded using a structured light pattern, and a third depth may be recorded using a light-field camera. Weighting factors may be applied to each of the recorded depths and a final, weighted depth may be computed.

Steerable endoluminal punch with introducer

An endoluminal punch system including a sheath and dilator. The endoluminal punch may include energy delivery system capable of being transmitted from the proximal end to the distal end of the endoluminal punch to assist with tissue crossing and incisions. The dilator may include selectively deployable cutting mechanism to create incisions in tissue that are larger than their basic external diameter. The system may also be configured to reduce the risk of generating plastic emboli during insertion of the endoluminal punch.
