84 results about "Anatomical part" patented technology

Disclosed is a concept for computer-assisted procedures of surgery and diagnosis that target rigid, non-deformable anatomical parts such as bone, tissue, or teeth. The disclosure describes attaching small visual markers to instruments and anatomy of interest (e.g. bone surface), with each marker having a printed known pattern for detection and unique identification in images acquired by a free-moving camera, and a geometry that enables estimating its rotation and translation with respect to the camera using solely image processing techniques.

A system automatically compares radiotherapy 3D X-Ray images and subsequent images for update and re-planning of treatment and for verification of correct patient and image association. A medical radiation therapy system and workflow includes a task processor for providing task management data for initiating image comparison tasks prior to performing a session of radiotherapy. An image comparator, coupled to the task processor, in response to the task management data, compares a first image of an anatomical portion of a particular patient used for planning radiotherapy for the particular patient, with a second image of the anatomical portion of the particular patient obtained on a subsequent date, by image alignment and comparison of image element representative data of aligned first and second images to determine an image difference representative remainder value and determines whether the image difference representative remainder value exceeds a first predetermined threshold. An output processor, coupled to the image comparator, initiates generation of an alert message indicating a need to review planned radiotherapy treatment for communication to a user in response to a determination the image difference representative remainder value exceeds a predetermined threshold.

Certain embodiments of the present invention provide a system and method for image registration and display of relevant information. The method includes identifying one or more anatomical parts in an acquired image, mapping the acquired image to a reference image based on the one or more anatomical parts, storing anatomy information in relation to the acquired image, and displaying the acquired image based on the anatomy information. The method may also include controlling the displaying of the acquired image based on a voice command related to the anatomy information. Anatomy information may be displayed with the acquired image. Anatomy information may include clinical information, reference information, disease process information, a related image, and / or drug interaction information, for example. The acquired image may be displayed according to a display setting, such as a window level setting and / or other display setting, based on the anatomy information.

The application provides methods for providing a surgical guide for placement on an anatomical part wherein the guide is provided with one or more dedicated push features that can be used as pressure points for applying force onto the surgical guide. The application further provides guides comprising one or more push features which can be used as a pressure point for applying force onto said guide.

A surgical instrument for harvesting vessels from the body includes an elongated shaft having distal and proximal ends and a plurality of lumens disposed therethrough. The shaft also includes a tip having a dissecting portion disposed at a distal end thereof and a cradle section. The tip is movable from a first position proximate the distal end of the shaft to at least one additional position distally further from the distal end of the shaft to expose the cradle section. The instrument also includes an endoscope disposed in one of the plurality of lumens and at least one additional surgical instrument disposed in one of the remaining lumens. Methods are disclosed for utilizing the surgical instrument.

A negative impression of an anatomical portion of a person is captured by forcing the anatomical portion into impression foam to collapse the impression foam into the negative impression. The impression foam has a crush characteristic of approximately constant resistance force over a relatively wide predetermined range of collapse distances. The negative impression is obtained by collapsing the impression foam within the range of constant-force collapse distances, thereby creating the negative impression under conditions which reflect an equally-loaded anatomical portion. A cushion support contour created from the equally-loaded negative impression is beneficial in more appropriately supporting the anatomical portion. The present invention is particularly useful in fabricating wheelchair seat cushions.

The invention relates to an MR(mixed reality)-based 3D visualized auxiliary diagnosis and treatment system that comprises a data preprocessing unit for receiving a medical image provided by a hospitalon a cloud platform, and converting the medical image into a commonly used Dicom format for subsequent digitization processing; a 3D reconstruction unit for volume rendering the medical image by using a reconstruction technology in a vtk environment, generating an available STL format, then manually processing a 3D model to improve the model; a model uploading unit for converting the format of the model to generate a file format available for a MR system and uploading a file; and an auxiliary medical treatment unit for covering the human body with the 3D model by a MR device through a visualoverlay technology during an operation to help a doctor perform the operation. The application of the auxiliary diagnosis and treatment system in the medical field solves the problem that the doctor cannot perform the accurate operation by enabling the 3D displayed human body structure to correspond to the actual anatomical parts of a patient during the operation.

A method for detecting a protrusion in a medical image includes: acquiring a medical image, wherein the medical image is of an anatomical part; segmenting the medical image; calculating a distance map of the medical image; calculating a gradient of the distance mapped medical image; and processing the gradient to detect a protrusion in the medical image. The gradient is processed by: projecting a plurality of rays from a location in the distance mapped medical image; calculating a value for each of the plurality of rays based on features of each of the plurality of rays and the gradient of the distance mapped medical image; summing and scaling the value of each of the plurality of rays; and detecting one of a sphere-like and polyp-like shape using the summed and scaled values of the plurality of rays, wherein one of the sphere-like and polyp-like shapes is the protrusion.
