摘要： An integrated radiation detector having a pulse-mode operating photosensor optically coupled to a gamma sensing element and a neutron sensing element is disclosed. The detector includes pulse shape and processing electronics package that uses an analog to digital converter (ADC) and a charge to digital converter (QDC) to determine scintillation decay times and classify radiation interactions by radiation type. The pulse shape and processing electronics package determines a maximum gamma energy from the spectrum associated with gamma rays detected by the gamma sensing element to adaptively select a gamma threshold for the neutron sensing element. A light pulse attributed to the neutron sensing element is a valid neutron event when the amplitude of the light pulse is above the gamma threshold.

摘要： A technique for acquiring desired image data in an imaging system comprising at least one radiation source and a detector is described. Initially, preliminary image data corresponding to an object may be acquired. Further, at least one parameter associated with the radiation source and corresponding to a particular view angle of the radiation source may be determined based on the preliminary image data and a priori information. Similarly, at least one parameter associated with the detector and corresponding to the particular view angle may be determined based on a priori information and the preliminary image data. Efficient operating modes of the radiation source and the detector corresponding to the particular view angle may be selected based on the determined parameters to achieve a desired system performance. Subsequently, the final image data may be acquired using the selected operating modes of the radiation source and the detector.

摘要： An x-ray diffraction imaging device includes at least one x-ray detector and at least one scatter collimator positioned upstream of the at least one x-ray detector. The at least one collimator includes a plurality of successive plates. Each of the plurality of plates defines a plurality of rectangular holes. The plurality of successive plates are arranged such that the plurality of rectangular holes define a plurality of quadrilateral passages extending through the at least one scatter collimator. Each of the plurality of quadrilateral passages is configured to increase a rate of detection of first x-rays that define an x-ray transit path enclosed within a single such quadrilateral passage. Also, the plurality of quadrilateral passages is configured to decrease a rate of detection of second x-rays that define an x-ray transit path that intersects more than one such quadrilateral passage.
