SYSTEMS FOR EVALUATING REGISTERABILITY OF ANATOMIC MODELS AND ASSOCIATED METHODS

Devices, systems, methods, and computer program products for planning medical procedures are disclosed herein. In some embodiments, a system for planning a medical procedure includes a processor and memory operably coupled to the processor. The memory stores instructions that, when executed by the processor, cause the system to perform operations including receiving a three-dimensional model of an anatomic region of a patient and evaluating whether the three-dimensional model is suitable for use in a registration procedure to be performed in the anatomic region. The evaluating includes: analyzing a span of the three-dimensional model along at least two different directions, determining whether the three-dimensional model includes at least one segmented component corresponding to at least one structure of the anatomic region, and performing a registration between the three-dimensional model and a virtual registration data set.

System And Method For Artifact Reduction In An Image

Selected artifacts, which may be based on distortions or selected attenuation features, may be reduced or removed from a reconstructed image. Various artifacts may occur due to the presence of a metal object in a field of view. The metal object may be identified and removed from a data that is used to generate a reconstruction.

Cochlear implant localization system

A navigation system or combination of navigation systems can be used to provide one or more navigation modalities to track a position and navigate a single instrument in a volume. For example, both an Electromagnetic (EM) and Electropotential (EP) navigation system can be used to navigate an instrument within the volume. The two navigation systems may be used separately to selectively individually navigate the single instrument in the volume. Disclosed are also systems and processes to determine a shape of the single instrument either alone or in combination with the position of the instrument. The instrument may be navigated with the addition of tracking devices or with native or inherent portions of the instrument.

Mobile imaging ring system

The present invention provides a mobile imaging system for imaging of patients in medical interventions comprising a ring gantry with a plurality of independently rotating rings whereas a first rotating ring positions an X-ray source with collimator and a second rotating ring positions an image detector such that the region of interest (patient) can be positioned off-centered with respect to the ring center. The system supports planar X-ray imaging and Computed Tomography (CT) and Cone beam CT (CBCT) acquisitions of three dimensional (3D) volumes with variable X-ray field of views (FOVs) adapted to regions of interest (ROIs), which are not required to be of cylindrical shape. The mobile system can be equipped with stereoscopic cameras integrated in the gantry an on moving rings to support optical tracking and navigation of instruments within the same co-ordinate system of X-ray information. The gantry can be equipped with additional sensors and robotic manipulators on further rings operating in said co-ordinate system on mobile platform. The gantry provides a generic mechanical and electrical interface to a supporting structure, which can be attached to a variety of mobility platforms to support robotic positioning of the system in various orientations of scanner in treatment rooms to accommodate a wide range of patient setups, including the possibility for inclined and vertical scans of patients in upright position.

SURGICAL GUIDANCE DEVICE
20230293217 · 2023-09-21 ·

Briefly, the invention relates to a surgical tool and method for forming a pilot bore by inserting a guide wire into bone. The surgical tool is constructed and arranged for use in conjunction with X-ray or ultrasound machines. 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. Should it be desired that the wire be retracted, a jack member is included to allow the wire to be precisely retracted. The hand grip is securable to various surgical driving tools for the purpose of providing the ability to cooperate with various brands of pedicle screws and other surgical implants for spinal procedures.
