  • Patent number: 11317971
    Abstract: A surgical implant planning computer positions an implant device relative to a bone of a patient. An initial image of a bone is obtained. An initial location data structure is obtained that contains data defining mapping between locations on the implant device and corresponding locations relative to the bone in the initial image. A target image of the bone of the patient is obtained. A transformation matrix is generated that transforms a contour of a portion of the bone in the initial image to satisfy a defined rule for conforming to a contour of a corresponding portion of the bone in the target image. A transformed location data structure is generated based on applying the transformation matrix to the initial location data structure. A graphical representation of the implant device is displayed overlaid at locations on the target image of the bone determined based on the transformed location data structure.

  • Patent number: 10682107
    Abstract: Three-dimensional imaging of a breast tissue is achieved by acquiring a series of X-ray projection images from various angles. A three-dimensional image constructed from the projection images by a computer provides information to the operator to select a coordinate point within the breast from which to obtain a biopsy sample. Acquisition of projection images and construction of three-dimensional images is continued during the insertion of the needle into the breast, during positioning the needle towards the coordinate point, during the sampling and after the sampling. The advantages of utilizing tomosynthesis for breast tissue imaging over stereo imaging include better image quality, easier coordinate measurements within a tissue, ease of use of the equipment by the medical personnel, and fewer image artifact problems.

  • Patent number: 9230473
    Abstract: A head-mounted display (HMD) device is provided with reduced motion blur by reducing row duty cycle for an organic light-emitting diode (LED) panel as a function of a detected movement of a user's head. Further, a panel duty cycle of the panel is increased in concert with the decrease in the row duty cycle to maintain a constant brightness. The technique is applicable, e.g., to scenarios in which an augmented reality image is displayed in a specific location in world coordinates. A sensor such as an accelerometer or gyroscope can be used to obtain an angular velocity of a user's head. The angular velocity indicates a number of pixels subtended in a frame period according to an angular resolution of the LED panel. The duty cycles can be set, e.g., once per frame, based on the angular velocity or the number of pixels subtended in a frame period.

In one embodiment, a method of treating a patient is provided which involves identifying a patient having a condition of excessive sweating, positioning an energy delivery device proximate to a skin tissue of the patient and delivering energy to sweat glands to halt secretion of sweat. The energy delivery device may include microwave delivery devices, RF delivery devices, and cryogenic therapy devices. Some embodiments may include using a cooling element for avoiding destruction of non-target tissue and/or a suction device to localize treatment at specific portions of the skin fold.

  • Patent number: 9028468
    Abstract: A robotic arm especially suited for laparoscopic surgery, having a torsional joint and a flexural joint forming serially arranged joints is described. The joints provide respective degrees of freedom for the arm, which further receives drive means for such joints. The robotic arm also has transmission means placed between the drive means have and the joints. The transmission means a first and a second assembly of three gear wheels, preferably conical gear wheels, and a train of three additional gear wheels, preferably straight-cut gear wheels, which couple the first and second assembly to form a differential mechanism.

  • Patent number: 9014784
    Abstract: Apparatus associated with improved magnetic resonance imaging (MRI) guided needle biopsy procedures (e.g., breast needle biopsy) are described. One example apparatus includes a support structure configured to support a patient in a face-down prone position where a breast of the patient is positioned in a first free hanging pre-imaging position. The example apparatus includes an immobilization structure configured to reposition the breast into an immobilized position suitable for MRI and for medical instrument access. The immobilization structure may include a biopsy plate, a pressure plate, and MRI coils. The MRI coils are configured to be repositioned from a first position associated with the free hanging pre-imaging position to a second position associated with the immobilized position to facilitate improving the signal to noise ratio associated with signal received from the breast through the MRI coils. The biopsy plate is removable without removing either of the MRI coils.

  • Patent number: 9008755
    Abstract: An inventive medical imaging marker includes a base (2) composed of a non-imageable material, three spherical members (10, 11, 12) provided in a predetermined positional relationship in the base (2) and each composed of an imageable material, and auxiliary marker members (20, 21, 22) provided in the base (2) and composed of the imageable material. The auxiliary marker members (20, 21, 22) respectively have linear portions (20L, 21L, 22L) which are disposed parallel to straight lines extending through center points of the three spherical members (10, 11, 12) and each have a predetermined length sufficient to serve as a mark. The center points of the three spherical members (10, 11, 12) can be correctly identified in a captured image with reference to the linear portions (20L, 21L, 22L) of the auxiliary marker members (20, 21, 22) of the inventive medical imaging marker. Thus, reference axes can be correctly defined in the image.

  • Publication number: 20150073259
    Abstract: An image-guided system and method for performing needle biopsy on a moving lung nodule of a body is provided. CT images of the lung nodule are obtained to generate a motion model, based on which an optimal needle advancing path is determined. The motion of the lung nodule and the motion of a fiducial marker attached to the body are correlated. The motion of the fiducial marker is tracked and monitored by a camera to determine a position of the lung nodule based on the correlation. A time for advancing the needle is determined based on a motion attribute of the reference. The needle is advanced by a robotic needle manipulator at the predetermined time along the path to accomplish the needle placement.
