  • Patent number: 8979859
    Abstract: A method for determining a depth of impaction of a prosthetic cup into an acetabulum using an end effector and a movable impactor shaft is provided, wherein the prosthetic cup may be positioned at a distal end of the impactor shaft. The method may position the distal end of the impactor shaft at a known pose relative to the end effector, track a spatial pose of the end effector relative to a spatial pose of the acetabulum, determine a spatial pose of the prosthetic cup based on the spatial pose of the end effector and the known pose between the distal end of the impactor shaft and the end effector, and determine the depth of impaction based on the spatial pose of the prosthetic cup and the spatial pose of the acetabulum.

  • Patent number: 7522701
    Abstract: Certain embodiments of the present invention provide systems and methods for image composition. Certain embodiments include acquiring a first image of an object using an imager, obtaining first positional information for the imager with respect to the object, acquiring a second image of the object using the imager, obtaining second positional information for the imager with respect to the object, and creating a composed image using the first and second images. A spatial relationship between the images is maintained using the positional information. A composed image may be created by constructing a memory map of image data related to the object and inserting the images into the memory map based on the positional information, for example. A composed image may be created by combining the images based on the positional information, for example.

  • Publication number: 20090080737
    Abstract: Certain embodiments of the present invention provide systems and methods of improved medical device navigation. Certain embodiments include acquiring a first image of a patient anatomy, a second image of patient anatomy, and creating a registered image based on the first and second images. Certain preferred embodiments teach systems and methods of automated image registration without the use of fiducial markers, headsets, or manual registration. Thus the embodiments teach a simplified method of image registration that allows a medical device to be navigated within a patient anatomy. Furthermore, the embodiments teach navigating a medical device in a patient anatomy with reduced exposure to ionizing radiation. Additionally, the improved systems and methods of image registration provide for improved accuracy of the registered images.

  • Publication number: 20080109012
    Abstract: System, method and apparatus are provided through which in some embodiments, a tool interface unit (TIU) of a medical navigation system or an integrated medical imaging and navigation system includes a wireless transceiver to communicate with a navigation computer in order to reduce or eliminate cabling between the TIU and the navigation computer. In some embodiments, the TIU is mounted to a side of a surgical table in order to reduce the possibility of contamination of the cables from a non-sterile environment. In some embodiments, the TIU is battery powered and includes a battery and a battery charger.

  • Patent number: 6400798
    Abstract: A preferred embodiment of the present invention provides a method and apparatus for correcting the offset induced by Field Effect Transistor (FET) photo-conductive effects in a solid state X-ray detector. The method and apparatus include reading out twice as many rows (scan lines) as actually exist in the X-ray detector. The additional rows may be read out between the actuation of “real” scan lines on the X-ray detector. The additional row times may be used to measure the “signal” induced by FET photo-conductivity. In a preferred embodiment, the “real” rows may be actuated during odd lines, and even lines will be used to measure the signal induced by FET photo-conductivity. To correct for the offset induced by photo-conductive FETs, an even row signal may be subtracted from the preceding odd row signal. The correction for the offset induced by photo-conductive FETs may occur in addition to normal offset correction.
