  • Patent number: 11686799
    Abstract: In a method and magnetic resonance (MR) apparatus for generating a combined MR image of an examination object, a first image data record of an examination object, generated from magnetic resonance data recorded with a first reception coil, is loaded into a computer. A second image data record of the examination object, generated from magnetic resonance data recorded with a second reception coil, wherein the first and the second reception coils are different reception coils, is also loaded into a computer. At least one interim image data record is generated by the computer by applying a mask function to the first and/or second image data record. An interim image data record is combined in the computer with the image data record to which no mask function was applied, or with the other interim image data record, to form a combined MR image.

A gaze direction of the user wearing the HMD, is detected using one or more gaze detecting cameras of the HMD that are directed toward one or each eye of the user. Images captured by the forward facing cameras are analyzed to identify an object captured in the real-world environment that is in line with the gaze direction of the user, wherein the image of the object is rendered at a first virtual distance that causes the object to appear out-of-focus when presented to the user. A signal is generated to adjust a zoom factor for lens of the one or more forward facing cameras so as to cause the object to be brought into focus.

  • Patent number: 11534183
    Abstract: Devices, apparatus and methods for patient-specific MIS procedures. A patient-specific, MIS navigation guide device may include a main body having a proximal surface and a distal surface, wherein the distal surface is configured to face target tissue upon placement of said MIS navigation guide device. Anchors extend distally of the distal surface, and distal ends of the anchors lie on a three dimensional surface that matches contours of the target tissue in locations where the anchors are designed to contact. An operational guide is configured to guide the performance of a surgical operational step on the target tissue along an optimal pathway predefined by the operational guide relative to the main body. A position indicator on the device is interpretable by a surgeon to know when the anchors have not yet been contacted to the target tissue in a predetermined orientation and to know when the anchors have been contacted to the target tissue in the predetermined orientation.

  • Patent number: 11534249
    Abstract: A method is described for performing a percutaneous operation on a patient to remove an object from a cavity within the patient. The method includes advancing a first alignment sensor into the cavity through a patient lumen. The first alignment sensor provides its position and orientation in free space in real time. The alignment sensor is manipulated until it is located in proximity to the object. A percutaneous opening is made in the patient with a surgical tool, where the surgical tool includes a second alignment sensor that provides the position and orientation of the surgical tool in free space in real time. The surgical tool is directed towards the object using data provided by both the first and the second alignment sensors.

  • Patent number: 11536554
    Abstract: A localization and attitude estimation method using magnetic fields includes the following steps. First, in three-dimensional coordinates, at least three magnetic landmarks arbitrarily disposed around a moving carrier are selected, wherein any two of the at least three magnetic landmarks have different magnetic directions. One set of at least five tri-axes magnetic sensors is used to sense the magnetic fields of the at least three magnetic landmarks. Three magnetic components on three axes of a current position of each of the tri-axes magnetic sensors are respectively generated by a demagnetization method. Five non-linear magnetic equations are solved to obtain position information and magnetic moment information of the at least three magnetic landmarks in the three-dimensional coordinates. Position vectors and attitude vectors of the set of at least five tri-axes magnetic sensors in a three-dimensional space are estimated based on tri-axes magnetic moment vectors of the magnetic landmarks.
