20090149738 | Chest Wall Coil Array for Breast Imaging - A RF coil array is provided for imaging a chest wall of a patient including a breast. The RF coil array includes a rigid cup-shaped element and a flexible, substantially flat portion. The rigid cup-shaped element is sized and dimensioned to receive a small breast, such as a post mastectomy breast or a male breast, and the flexible portion is configured to be conformed to the patient adjacent the breast to allow for imaging of the breast, and adjacent areas while facing the chest wall. | 06-11-2009 |
20090216110 | Open Architecture Tabletop Patient Support and Coil System - A patient support structure for positioning a selected anatomy of interest for imaging in a magnetic resonance imaging scanner is disclosed. The structure includes a receptacle for receiving a removable tray that includes connectors for connecting local RF coils housed in the array to the MRI scanner, and connectors for positioning the local RF coils adjacent an area of interest to be imaged. A structure for elevating the patient support is also disclosed. | 08-27-2009 |
20130053684 | OPEN ARCHITECTURE TABLETOP PATIENT SUPPORT AND COIL SYSTEM - An assembly for magnetic resonance imaging (MRI) of a patient and a method of magnetic resonance imaging (MRI) of a patient using different MRI scanners is disclosed. In one example, the assembly includes a plurality of RF coils, wherein the RF coils are configured to be positioned adjacent to an anatomy of interest, a patient support structure configured to support of the patient, a base removably coupled to the patient support structure, the base and the patient support being configured for receipt in the bore of an MRI scanner, and an interface coupled to the plurality of RF coils and to the MRI scanner and configured to connect the plurality of RF coils and the MRI scanner and to selectively control a first RF coil and a second RF coil included in the plurality of RF coils. | 02-28-2013 |
20140276007 | Surgical Pointer Having Constant Pressure - A medical navigation system having a surgical pointer is provided. The surgical pointer is used in the medical navigation system. The surgical pointer comprises an external sheath and an internal tool having a proximal end and a distal end. The internal tool is contained at least partially within the external sheath. The internal tool has a tip at the distal end that extends beyond the external sheath. The tip engages a surface of a patient. The internal tool further has a tracking marker trackable by the navigation system. The surgical pointer further has a linking component contained at least partially within the external sheath and interfacing with the internal tool. The linking component is configured to control pressure exerted by the tip on the surface of the patient. | 09-18-2014 |
20150109427 | SURGICAL IMAGING SYSTEMS - Systems, methods and devices are provided for illuminating tissue with monochromatic or broadband light and imaging light that has been reflected back from the tissue. Imaging may be white-light imaging or hyperspectral imaging. The system can be a stand-alone hyperspectral imaging system, integrated as part of an external video scope, or as an auxiliary imaging module on an external videoscope. Various elements of a video scope that is particularly suited for minimally invasive surgery is first presented and then its configurations suitable for hyperspectral imaging are explained. | 04-23-2015 |

In one example, the assembly includes a plurality of RF coils, wherein the RF coils are configured to be positioned adjacent to an anatomy of interest, a patient support structure configured to support of the patient, a base removably coupled to the patient support structure, the base and the patient support being configured for receipt in the bore of an MRI scanner, and an interface coupled to the plurality of RF coils and to the MRI scanner and configured to connect the plurality of RF coils and the MRI scanner and to selectively control a first RF coil and a second RF coil included in the plurality of RF coils. | 05-21-2015 |
20150351860 | SYSTEMS AND METHODS FOR NAVIGATION AND SIMULATION OF MINIMALLY INVASIVE THERAPY - Disclosed herein is navigation and simulation systems and methods for minimally invasive therapy in which the navigation system imports a planning method using patient specific pre-operative images. The navigation system uses intraoperative imaging during the medical procedure to update the preoperative images and provides images of tracked surgical tools along the surgical path prepared from the preoperative images. | 12-10-2015 |
20160000515 | SYSTEM AND METHOD FOR DYNAMIC VALIDATION, CORRECTION OF REGISTRATION FOR SURGICAL NAVIGATION - Disclosed herein is a system and method for dynamic validation, correction of registration for surgical navigation during medical procedures on a patient which involves confirmation of registration between one or more previously registered virtual objects, such as surgical tools etc. in a common coordinate frame of a surgical navigation system and an operating room, and intra-operatively acquired imaging during the medical procedure in the common coordinate frame. The method includes displaying intra-operatively acquired imaging of the surgical field containing the one or more real objects corresponding to the one or more previously registered virtual objects, with the real objects being tracked by a tracking system. The method overlaying a virtual image containing the previously registered virtual objects onto the intra-operatively acquired imaging, from the point of view of the intra-operatively acquired imaging, and detecting for any misalignment between any one of the one or more previously registered virtual objects contained in the virtual image and its corresponding real object contained in the intra-operatively acquired imaging. | 01-07-2016 |
20160005169 | SYSTEM AND METHOD FOR DETECTING TISSUE AND FIBER TRACT DEFORMATION - Disclosed herein is a method for producing an evolvable tissue model of a patient and, using this model, modelling physical transformations of the tissue (e.g. deformation) of the tissue model by interacting the tissue model with influence models which model interactions with the tissue such as surgical instruments, pressure, swelling, temperature changes etc. The model is produced from a set of input data of the tissue which includes directional information of the tissue. The directional information is used to produce an oriented tissue map. A tissue model is then produced from the oriented tissue map such that the tissue model reflects the directionality of the tissue component. When the tissue model is subjected to an influence that causes tissue deformation over a period of time, the tissue model directionally deforms over the period of time in a manner which reflects a trajectory of the influence interacting with the directionality of the tissue component. | 01-07-2016 |
