  • Patent number: 10209124
    Abstract: According to the invention, a PIR sensor system (100) comprises a first PIR sensor (1) associated with a first sensing region (11) and a second PIR sensor (2) associated with a second sensing region (12). The first and second sensing regions partially overlap and are divided into detection cells (46a-46f) and (45a-45d). Each detection cell is represented by predetermined characteristics of first and second output signals, which signals are based on input signals from first and second sensing elements (4-7) of each PIR sensor. Thereby different detection cells are encoded by a certain combination of signal characteristics (amplitude and sign) of the first and second output signals. Further, the PIR sensor system comprises a processing unit (15) configured to associate the characteristics of the first and second output signals with one of the detection cells for determining in which of the detection cells a heat source is positioned.

  • Patent number: 10048392
    Abstract: Methods, systems, and computer-readable mediums are provided that determine the angular orientation of detectors and detector electronic assemblies (“DEAs”). In various embodiments, the orientation of detectors/DEAs (in the ring) is determined with respect to other detectors/DEAs in the ring, the orientation of the detectors/DEAs with respect to a patient bed, or the orientation of the detectors/DEAs with respect to Earth's gravitational field. In another embodiment, a nuclear medical imaging system has one or more detector units arranged around or that can be swept around a patient bed. Each of the detector units includes an angular orientation-sensing accelerometer. By determining angular orientation of the detector from signals outputted by the accelerometer, the circumferential position of the detector relative to the patient bed can be determined. That information is used in conjunction with information about detected events to construct an image of an organ or tissue mass of interest.

  • Patent number: 10041837
    Abstract: The present invention relates to a radiation imaging sensor with at least one detection element, which is implemented on a substrate as a micromechanical resonator and which absorbs the radiation to be detected. The resonator is set into a resonant oscillation with an excitation device and a shift in the resonance frequency of the detection element under exposure to radiation is detected with a detection device. The radiation sensor is characterized by the fact that it comprises a scanning device with a single-axis or multi-axis tiltable scanning element. The facility to tilt the device means that the detection element can be used to detect radiation from different directions. The imaging sensor can be realized in a compact manner and be economically produced.

  • Patent number: 9820710
    Abstract: Provided is a preview image generating section configured to generate preview image during radiography for the purpose of providing a radiation tomography apparatus that allows suppression of unnecessary imaging time by displaying a condition of an image during the radiography in the process of diagnosis. An operator can recognize from the preview image how a subject appears in the image in a radiation tomography apparatus also during the radiography. This allows stopping the radiography before a diagnostic image having a suitable level of clearness for diagnosis is generated. As a result, a shorter imaging time is achieved, and burden to the subject can be suppressed.
