摘要： A radiation detector head assembly includes a detector column including a detector having a first surface and a second surface opposite the first surface. The detector column includes a first collimator disposed over the first surface of the detector and a second collimator disposed over the second surface of the detector. The detector column includes a first radiation shield disposed over the first collimator, wherein the first radiation shield includes a first recess for receiving the first collimator and a first opening over a third surface of the first collimator, the third surface being opposite the first surface of the detector. The detector column includes a second radiation shield disposed over the second collimator, wherein the second radiation shield includes a second recess for receiving the second collimator and a second opening over a fourth surface of the second collimator, the fourth surface being opposite the second surface.

摘要： A system (1) for monitoring the exposure of a plurality of individuals (5) to a physical or chemical property associated with an environment. The system includes a plurality of portable devices (9). Each portable device is arranged to be worn or carried by an individual in the environment. The system further includes a control unit (7) for communicating with each of the plurality of portable devices. Each of the portable device includes a detector arranged to measure a physical or chemical property that the individual wearing or carrying the device is exposed to in the environment; one or more physiological sensors each arranged to measure a physiological parameter of the individual; a geolocation module arranged to determine the location of the individual; and a communication module for communicating data collected by the portable device with other(s) of the plurality of the portable devices and with the control unit.

摘要： The present invention relates to X-ray imaging. In order to improve artefacts management, there is provided an anomaly detection apparatus for identifying disturbance in an X-ray detector image caused by an external source. The anomaly detection apparatus comprises an input unit, a processing unit, and an output unit. The input unit is configured to receive an unexposed image acquired by an X-ray detector and metadata associated with the acquired unexposed image. The processing unit is configured to analyse the received unexposed image to determine whether there is an anomaly in the received unexposed image that is indicative of an image disturbance caused by an external source. In response to the detection of an anomaly that is indicative of an image disturbance caused by an external source, the processing unit is configured to generate a single image anomaly report comprising the received unexposed image in full or data-size-reduced form and the received metadata. The output unit is configured to provide the generated single image anomaly report.

摘要： Provided is an imaging device with low noise and a high dynamic range.
An imaging device includes: a conversion unit that converts an incident electromagnetic wave into a charge; a first capacitor that accumulates the charge when a voltage corresponding to the charge is equal to or lower than a predetermined threshold; a second capacitor that accumulates the charge when the voltage exceeds the threshold; a voltage conversion circuit that converts the charges accumulated in the first capacitor and the second capacitor into voltages; a first storage unit that stores a voltage corresponding to the accumulated charge in the first capacitor after a lapse of a first period since the first capacitor has started accumulating the charge; and a second storage unit that stores a voltage corresponding to the accumulated charges in the first capacitor and the second capacitor after a lapse of a second period longer than the first period since the first capacitor has started accumulating the charge.
