  • Patent number: 10357666
    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.

    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: 9737277
    Abstract: An X-ray CT system and a method of processing medical images are provided that enable combining of images with reduced effect of the differences in coordinates of the pixels in the overlapped areas of a plurality of constituent images. The X-ray CT system includes a processor and a synthesizer. Based on coordinates of first pixels in a first image of a first three-dimensional region of the subject and coordinates of second pixels in a second image of a second three-dimensional region of the subject, the processor combines the first pixels with the second pixels on a one-for-one basis within a predetermined range in the rostrocaudal direction. The synthesizer generates third pixels relative to the first pixels and the second pixels and generates a third image that includes the third pixels.

  • Patent number: 9737280
    Abstract: The present invention relates to acquisition of medical image information of an object. In order to provide a user-friendly alignment of X-ray tube and a detector, optionally combined with an anti-scatter grid, an alignment arrangement is proposed, which comprises a tube attachment with a first light projection device and a detector attachment with a second light projection device. The first and second light projection devices each generate a light pattern on a projection surface. The tube attachment and the detector attachment can be brought into a correct spatial arrangement relative to each other by bringing the first light pattern in a predetermined spatial relation with the second light pattern on the projection surface.

  • Patent number: 9599580
    Abstract: A method and device that analyzes a sample with a diffractometer that includes a collimated source, a spectrometric detector, and a detection collimator. The sample is irradiated with an incident beam and the detector has a detection plane with multiple physical or virtual pixels. An measured energy spectrum is established for each pixel and each measured energy spectrum is readjusted. The spectrum is expressed as a function of a variable that accounts for the energy of the scattered radiation and an angle of diffraction. The fulfillment of at least one multiple material criterion is verified. Groups of pixels are formed using the results of the verification step, each group corresponding to a layer of material and different groups corresponding to different layers of material, and the spectra are combined by group, during which, for each group, the readjusted spectra for the pixels of the group are combined.

    Abstract: Systems and related methods are provided to perform optical characterization of system under tests (SUT), including one or more optical elements (OE), for various purposes including evaluation of optical resolution needed to distinguish image elements, blur, line of sight jitter, and/or pointing stability. Various testing systems and methods are provided including an embodiment having a vibration loading system (VLS), a first acceleration sensor coupled with the VLS, and a mounting structure adapted to receive the SUT. An illumination target system (ITS) emits light that passes through the SUT OE's lens and is captured by the SUT's imaging system. A light control system controls the ITS based on a plurality of activation commands and a Test Control System (TCS). The TCS receives ITS input through the SUT that is synchronized with acceleration sensor data (e.g. phase of VLS position) and analyzed via real-time or post-processing.
