  • Patent number: 10852283
    Abstract: A system that may identify when a pulsed neutron generator is operating while disposed in an undesirable environment, such as in air, may include a pulsed neutron generator designed to emit neutrons in an environment. The system may also include a radiation detector designed to take measurements of the neutrons. The system may also include data processing circuitry designed to determine if the environment surrounding the pulsed neutron generator is air based at least in part on a neutron signal obtained by the radiation detector. The determination may include comparing one or more characteristics of the neutron signal with corresponding reference characteristics.

  • Patent number: 10852448
    Abstract: A PET detector array (8) comprising detector pixels acquires PET detection counts along lines of response (LORs). The counts are reconstructed to generate a reconstructed PET image (36, 46). The reconstructing is corrected for missing LORs which are missing due to dead detector pixels of the PET detector array. The correction may be by estimating counts along the missing LORs (60) by interpolating counts along LORs (66) neighboring the missing LORs. The interpolation may be iterative to handle contiguous groups of missing detector pixels. The correction may be by computing a sensitivity matrix having matrix elements corresponding to image elements (80, 82) of the reconstructed PET image. In this case, each matrix element is computed as a summation over all LORs intersecting the corresponding image element excepting the missing LORs. The computed sensitivity matrix is used in the reconstructing.

  • Patent number: 10848725
    Abstract: Systems and methods for allocating display colors to thermal image intensity data acquired by thermal band photodetectors. Intensity data from the photodetectors corresponding to scene temperature is converted to a digital value within an analog to digital conversion (ADC) range. The full ADC range may be divided into two or more sub-ranges. In one sub-range, intensity values within that sub-range are assigned display colors from a first color table utilizing one or more Histogram Equalization (HE) techniques. In another sub-range, specific display values from a color table different from the first may be are assigned to specific intensity values. Lower temperatures may be assigned colors using HE and higher temperatures are assigned specific colors corresponding to specific temperatures. Such an arrangement is particularly applicable to thermal imaging use by firefighters because the arrangement allows them to determine temperature directly from displayed color for potentially dangerous temperatures.

  • Patent number: 10838079
    Abstract: A first power supply unit supplies power to a first sensor panel and a first circuit unit. A second power supply unit supplies power to a second sensor panel and a second circuit unit. A synchronizing signal supply unit of a control unit supplies a synchronizing signal for synchronizing the operations of a switching power supply of the first power supply unit and a switching power supply of the second power supply unit to the switching power supply of the first power supply unit and the switching power supply of the second power supply unit. Since the operations of the first and second power supply units are the same in each imaging operation, it is possible to ensure the reproducibility of an X-ray image.

  • Patent number: 10837921
    Abstract: The aspects of the present disclosure are directed to a method and system for producing tomosynthesis images of a breast specimen with the capability of attaining images with geometric magnification. In one embodiment, an x-ray source delivers x-rays through a specimen of excised tissue and forms an image at a digital x-ray detector with the resultant image enlarging as the specimen is moved closer to the x-ray source. Multiple x-ray images are taken as the x-ray source moves relative to the stationary breast specimen. The source may travel substantially along a path while the detector remains stationary throughout and the source remains substantially equidistant from the specimen platform. The set of x-ray image data taken at the different points are combined to form a tomosynthesis image that can be viewed in different formats, alone or as an adjunct to conventional specimen radiography.

  • Patent number: 10837836
    Abstract: Infra-red sensors are often used in turbo molecular pumps to detect the temperature of the rotor or other mechanical parts and therefore indicate imminent, or potential, running failures. As deposits build up on either the infra-red sensor, or on the surface being monitored, the reading given by the sensor may not be a true representation of the actual surface temperature which can cause the pump controller to fail to stop the pump in time. The present invention provides a method and device for calibrating the sensor by creating a determined temperature rise in the sensor whilst keeping the rotor at ambient temperature. In particular the present invention uses the motor stator as the heater for causing the temperature increase.

  • Patent number: 10835194
    Abstract: A movable X-ray bucky assembly includes an X-ray track unit that is mounted to a ceiling of an X-ray room. The X-ray track unit includes a positioning rail that is slidable along a lateral axis of the X-ray track unit. An X-ray bucky mount is movably coupled to the positioning rail and the X-ray bucky mount is movable along a longitudinal axis of the positioning rail. Thus, the X-ray bucky mount can be positioned at a plurality of locations in the X-ray room. An X-ray detection panel is pivotally coupled to the X-ray bucky mount. Thus, the X-ray detection panel can be positioned adjacent to a patient regardless of the position of the patient within the X-ray room. In this way an X-ray image can be taken of the patient when the patient is not able to stand in front of a conventional wall mounted X-ray detection panel.

  • Patent number: 10816679
    Abstract: A large-area directional radiation detection system may include a large number of slab-shaped detectors stacked side-by-side and alternately displaced frontward and rearward, thereby providing a longitudinally-staggered array of protruding and recessed detectors. The protruding detectors collimate or restrict the lateral field of view of the recessed detectors, thereby enabling the angular position and distance of a source to be determined. The high detection efficiency and large solid angle of the staggered detector array enable rapid detection of even well-shielded threat sources at substantial distances, while simultaneously determining the positions of any sources detected. This detector array will be essential for guarding against clandestine delivery of nuclear materials in the coming century.

  • Patent number: 10809184
    Abstract: Properties of a sample that are dependent upon wavelength, such as IR absorption, can be detected and deconstructed into wavelets or other basis functions. These basis functions can be compared to determine which have a relatively high likelihood of being noise or signal, and an attenuation factor can be applied to each wavelet. A spectrum can be reconstructed from these wavelets that exhibits a significantly higher signal-to-noise ratio than raw data co-adding would produce in significantly less measurement time.
