A system configured to perform an accuracy check of a tracked instrument can include a processing circuitry and memory coupled to the processing circuitry. The memory can include instructions to cause the system to perform operations. The operations can include determining a virtual position of a display device. The operations can further include determining a virtual position of the tracked instrument. The operations can further include determining a point of contact on the display device between the tracked instrument and the display device. The operations can further include determining an expected point of contact on the display device between the tracked instrument and the display device based on the virtual position of the display device and the virtual position of the tracked instrument. The operations can further include determining whether the tracked instrument is accurate based on a difference between the point of contact and the expected point of contact.

A virtual model a planned instrument attachment can be provided to ensure correct selection of a physical instrument attachment. An XR headset controller can generate a shape and a pose of the virtual model of the planned instrument attachment based on predetermined information associated with the planned instrument attachment and based on a pose of an instrument relative to the XR headset. An XR headset can display the virtual model on a see-through display screen of the XR headset that is configured to allow at least a portion of a real-world scene to pass therethrough.

Computer systems and computer-implemented analysis methods may be used for assistance in planning and/or performing a medical procedure, such as percutaneous nephrolithotomy or percutaneous nephrolithotripsy. The method may include receiving one or more radiographic images of an anatomical structure of a patient, generating a display of the radiographic image(s), generating at least one request for user input to identify features of the anatomical structure, receiving user input identifying the features of the anatomical structure, identifying at least one access plan based on the received user input, and generating a display of the identified access plan(s) associated with the radiographic image(s). The method may include generating a patient template that indicates an insertion site according to the identified access plan(s).

Through the present invention, three-dimensional coordinates of a tracking object moving in an irradiation object can be calculated from fluoroscopic X-ray images captured and acquired from various angles in a single fluoroscopic X-ray device mounted to a radiation therapy apparatus. The three-dimensional coordinates of the tracking object are calculated on a straight tracking object presence line connecting an X-ray generating device for fluoroscopy and the position in an X-ray plane detector of the tracking object on the fluoroscopic X-ray image acquired by the X-ray generating device for fluoroscopy and the X-ray plane detector, and using line segment information included in a movement region of the tracking object set in advance.

A medical robot system, including a robot coupled to an effectuator element with the robot configured for controlled movement and positioning. The system may include a transmitter configured to emit one or more signals, and the transmitter is coupled to an instrument coupled to the effectuator element. The system may further include a motor assembly coupled to the robot and a plurality of receivers configured to receive the one or more signals emitted by the transmitter. A control unit is coupled to the motor assembly and the plurality of receivers, and the control unit is configured to supply one or more instruction signals to the motor assembly. The instruction signals can be configured to cause the motor assembly to selectively move the effectuator element.

Embodiments include a system for determining cardiovascular information for a patient. The system may include at least one computer system configured to receive patient-specific data regarding a geometry of the patient's heart, and create a three-dimensional model representing at least a portion of the patient's heart based on the patient-specific data. The at least one computer system may be further configured to create a physics-based model relating to a blood flow characteristic of the patient's heart and determine a fractional flow reserve within the patient's heart based on the three-dimensional model and the physics-based model.

The present disclosure relates to a C-arm. The C-arm may include a connection component, a driving component, a first support component, and a second support component. The first support component may be configured to support a radiation generator. The second support component may be configured to support a radiation detector. The first support component and the second support may be movably connected to the connection component. The driving component may be configured to drive a movement of the first support component relative to the connection component.

A camera tracking system is disclosed that is configured to obtain a model defining a tracking volume of a set of tracking cameras relative to pose of the set of tracking cameras, and receive tracking information from the set of tracking cameras indicating pose of an extended reality (XR) headset relative to the set of tracking cameras. The camera tracking system is further configured to generate a graphical representation of the tracking volume from a perspective of the XR headset based on the pose of the XR headset indicated by the tracking information and based the model defining the tracking volume of the set of tracking cameras, and provide the graphical representation of the tracking volume to the XR headset for display to the user.

Briefly, the invention relates to a surgical tool and method for forming a pilot bore by inserting a guide wire into bone. More particularly, the device includes a cannulated hand grip and driving tool used for the rotation of a bone or pedicle screw into bone. The rear portion of the hand grip includes a slide assembly that is suited to grip a guide wire. The slide assembly includes a user adjustable stop to control the sliding movement of the guide wire. The rear surface of the slide is constructed to be impacted with a hammer or similar device, whereby the stop prevents the guide wire from penetrating the bone further than desired. A jack member is included to allow the wire to be precisely retracted.
