    Abstract: A detector and methods for inspecting material on the basis of scintillator coupled by wavelength-shifting optical fiber to one or more photo-detectors, with a temporal integration of the photo-detector signal. An unpixelated volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides. This geometry provides for efficient and compact detectors, enabling hitherto unattainable geometries for backscatter detection and for energy discrimination of incident radiation. Additional energy-resolving transmission configurations are enabled as are skew- and misalignment compensation.

    Abstract: A method for the detection of X-ray quants is provided. The X-ray quants are generated in an X-ray tube and impact on a multi-pixel X-ray detector including a two-dimensional matrix of test-signal-generating pixels. The method includes assigning, by an evaluation unit, pixels that generate a test signal within a predetermined time interval and are located in a cohesive cluster including a plurality of pixels to an event cluster. The test signals are used to approximate a position, at which the X-ray quant has interacted with the multi-pixel X-ray detector.

  • Publication number: 20130093931
    Abstract: To avoid reset noise in a CMOS chip for direct particle counting, it is known to use Correlative Double Sampling: for each signal value, the pixel is sampled twice: once directly after reset and once after an integration time. The signal is then determined by subtracting the reset value from the later acquired value, and the pixel is reset again. In some embodiments of the invention, the pixel is reset only after a large number of read-outs. Applicants realized that typically a large number of events, typically approximately 10, are needed to cause a full pixel. By either resetting after a large number of images, or when one pixel of the image shows a signal above a predetermined value (for example 0.8×the full-well capacity), the image speed can be almost doubled compared to the prior art method, using a reset after acquiring a signal.

  • Publication number: 20130092843
    Abstract: A smart device “plug-in” radiation module(s) and/or methods are described wherein the bulk of non-sensor radiation circuitry is off-loaded to the smart device. By attaching the radiation module to the smart device via a power/communication port (for example, the smart device's headphone/microphone jack) robust attachment can be achieved as well as uniformity of attachment across different smart devices. A very small radiation module form factor is obtainable, not to mention a very significant cost reduction, allowing widespread adoption of radiation detectors as well as radiation geo-mapping. Power for the radiation module can be obtained from the smart device's headphone plug, utilizing the audio out (speaker) signal's power. Similarly, input to the smart device can be facilitated via the audio in (microphone) signal. Further, output of the radiation module can be visualized on the smart device, as well as control functions.

    Abstract: A radiological image detection apparatus includes an imaging unit, a storage unit, a correction data generating unit, a correction unit, a disturbance detection unit, and a determination unit. The imaging unit acquires radiological image data. The storage unit stores correction data for correcting the radiological image data.

The correction unit performs a correction process for the radiological image data using the correction data. The disturbance detection unit detects a disturbance acting when the imaging unit acquires the dark image data. The determination unit determines whether the updating of the correction data stored in the storage unit is permitted, or whether the acquisition of the dark image data is permitted, based on the detection result of the disturbance detection unit.

    Abstract: A radiographic image capture device includes a radiation detector, an application section and a controller. The radiation detector includes plural detection pixels that detect a radiation application state and plural imaging pixels that capture a radiographic image.

  • Publication number: 20130076712
    Abstract: An electronic device may have a display with a brightness that is adjusted based on ambient light data from multiple ambient light sensors. Sensors that are shadowed can be ignored. A touch sensor array in the display may have electrodes that overlap ambient light sensors. When a touch sensor signal indicates that an external object is covering one of the ambient light sensors, data from that ambient light sensor can be discarded. The ambient light sensors may include a primary ambient light sensor such as a human-eye-response ambient light sensor and may include an array of secondary ambient light sensors such as non-human-eye-response sensors. The secondary ambient light sensors may be formed on a display layer such as a thin-film-transistor layer and may be formed from thin-film materials. An algorithm may be used to dynamically calibrate non-human-eye-response ambient light sensors to the human-eye-response ambient light sensor.
