    Abstract: The invention comprises a fiducial marker—fiducial detector based treatment room position determination/positioning system apparatus and method of use thereof. A set of fiducial markers and fiducial detectors are used to mark/determine relative position of static and/or moveable objects in a treatment room using photons passing from the markers to the detectors. Further, position and orientation of at least one of the objects is calibrated to a reference line, such as a zero-offset beam treatment line passing through an exit nozzle, which yields a relative position of each fiducially marked object in the treatment room. Treatment calculations are subsequently determined using the reference line and/or points thereon. The treatment calculations are optionally and preferably performed without use of an isocenter point, such as a central point about which a treatment room gantry rotates, which eliminates mechanical errors associated with the isocenter point being an isocenter volume in practice.

  • Patent number: 10031148
    Abstract: An automated system for handling core samples in and out of an imaging device retrieves the samples from a staging area. During handling, the identity of each core sample is known to the system so that the imaging results are correlated appropriately. The system positions the core sample so the vertical and slab side orientations of the core sample discernable during handling. Core samples are staged in a location, and the automated system includes a robotic arm, which senses the core sample to discern its vertical and slab slot orientations, and then loads the core sample into the imaging device. When imaging is complete, the automated system removes the core sample from the imaging device; and in designated circumstances, transfers the core sample to a location for further analysis. In one example the further analysis is based on analyzing areas of interest identified in the core sample.

  • Patent number: 9987021
    Abstract: A method for determining a mechanical axis of a tibia using a tibial digitizer is disclosed. The method includes: determining an upper reference point on a tibial plateau corresponding to an entry point of the mechanical axis; fastening an upper mounting end of the tibial digitizer to the tibial plateau at the upper reference point; and fastening a lower mounting end of the tibial digitizer to medial and lateral malleoli of the ankle, by inwardly displacing opposed caliper arms of a self-centering malleoli engaging mechanism toward each other in a common plane until the caliper arms abut the malleoli. A lower reference point located at a midpoint between the medial and lateral malleoli is then determined by identifying a corresponding midpoint between the caliper arms when they are clamped onto the medial and lateral malleoli.

  • Patent number: 9945794
    Abstract: A scanning and imaging apparatus comprises a ray source configured to generate an X-ray and a detection device configured to receive an X-ray transmitted through an inspected object, wherein the ray source is configured to image the inspected object by emitting the X-ray to the inspected object. A radioactivity detector is configured to detect whether the inspected object comprises radioactive material synchronously with the process of scanning implemented by the scanning and imaging apparatus. In a case that the radioactivity detector detects radioactive material, an actual position of the radioactive material in an X-ray image of the inspected object obtained by the scanning and imaging apparatus is marked in the image. The above solutions improve the accuracy of displaying the position of the radioactive source in the X-ray image. Further, inspection of radioactive material can be implemented while scanning an image.
