摘要： A system for tracking a piece of medical equipment intraoperatively using a collinear array of fiducial markers positioned at known fixed distances relative to each other on the medical equipment and a camera capturing an image on a single image plane. Representations of the fiducial markers are segmented from a captured image, 3D orientation and position of the medical equipment are calculated using the segmented representations, and the orientation and position of the medical equipment are tracked relative to the camera. The orientation and position of the medical equipment may be registered within a 3D virtual space. The system may be used as part of a surgical navigation system.

摘要： Systems and methods for imaging a subject with a magnetic resonance imaging system using magnetic field gradients generated by one or more gradient coils operating with gradient coil settings, such as gradient amplitudes and gradient slew rates, above a threshold at which peripheral nerve stimulation is likely to be induced in the subject. A dielectric assembly is positioned adjacent a skin surface of the subject such that the dielectric assembly attenuates the local electric fields induced by the magnetic field gradients, which would be likely to induce PNS when the dielectric assembly is not arranged adjacent the skin surface of the subject. As a result of the dielectric assembly placed adjacent the skin surface of the subject, the gradient coil settings can be increased above the threshold without inducing PNS in the subject.

摘要： A computing device: compares an anatomical magnetic resonance (MR) image of a patient region and reference anatomical data associated with the region to determine a first transform of a bore anatomical coordinate space of the anatomical MR image to a patient anatomical coordinate space associated with the patient; determines, from the first transform, a second transform of a bore DWMR coordinate space of a DWMR image to a patient DWMR coordinate space associated with the patient, the anatomical and the DWMR images being in respective bore coordinate spaces associated with a bore of an MR device which acquired the anatomical and the DWMR images; transforms, using the second transform, the DWMR image to the patient DWMR coordinate space; and controls a display screen to render the DWMR image, as transformed, according to visual attributes associated with the patient DWMR coordinate space.

摘要： A method for performing auto-focus in a camera is disclosed. The method includes: receiving, from a tracking system for tracking a position of a medical instrument, a signal; determining, based on the received signal, that the medical instrument is removed from a field of view of the camera; in response to determining that a continuous auto-focus mode for the camera is enabled: retrieving, from a database, a first focus distance value representing a focus distance that was most recently set with intent for the camera; and automatically updating a focus distance of the camera to the first focus distance value.

摘要： A cognitive optical system for dynamically refining imaging during a medical procedure, involving a processor operable by a set of executable instructions storable in relation to a non-transitory memory device. The processor is configured to automatically adjust an image by automatically compensating for at least one external factor affecting an anatomical area being viewed, automatically adjusting at least one imaging parameter, and automatically adjusting at least one internal control of an optical chain, whereby a quality of the image is improvable in real time.

摘要： A phantom is disclosed containing fluorescence properties similar to anatomy that is needed to be visualized during surgical procedures. The phantom is created using substances including fluorophores that respond to UV light excitation to give visual cues of the phantom. The phantom can vary in phase and fluorescent properties depending on what it needs to simulate in the medical field with the purpose to help train users for surgical and diagnostic procedures, and develop, enhance, and calibrate imaging technology.

摘要： Systems and methods are provided for identifying a suitable surgical location and/or trajectory for proceeding with a surgical procedure based on local polarization-sensitive optical coherence tomography imaging (PS-OCT). PS-OCT images are obtained of a tissue region and are processed to provide a spatial map of anisotropic structure within the tissue region. The anisotropic structure is processed to determine one or more suitable surgical locations and/or trajectories for avoiding or reducing damage to local anisotropic tissue structure identified within the tissue region. The spatial map of the anisotropic structure is registered with pre-operative volumetric image data identifying anisotropic tissue structure within a second tissue region that is larger than the tissue region imaged by PS-OCT.
