摘要： When detecting scintillation events in a nuclear imaging system, time-stamping and energy-gating processing is incorporated into autonomous detection modules (ADM) (14) to reduce downstream processing. Each ADM (14) is removably coupled to a detector fixture (13), and comprises a scintillation crystal array (66) and associated light detect or (s) (64), such as a silicon photomultiplier or the like. The light detector(s) (64) is coupled to a processing module (62) in or on the ADM (14), which performs the energy gating and time-stamping.

摘要： A method of imaging analyte elements in an organic sample includes providing the sample as a layer on a substrate and reacting the sample on the substrate to produce one or more volatile products that leave the sample while the one or more elements remain in the sample. A majority of the sample layer by weight is removed from the substrate by the reaction and the remaining sample layer is enriched in the one or more elements which are not spatially disturbed by the reaction. The method including subsequently detecting the one or more elements in the concentrated sample layer using an imaging elemental analyzer.

摘要： The invention relates to radiation detection with a directly converting semiconductor layer for converting an incident radiation into electrical signals. Sub-band infra-red (IR) irradiation considerably reduces polarization in the directly converting semi-conductor material when irradiated, so that counting is possible at higher tube currents without any baseline shift. An IR irradiation device is integrated into the readout circuit to which the crystal is flip-chip bonded in order to enable 4-side-buttable crystals.

摘要： The invention relates to a radiation detection device for integrating the number of optical photons in a light pulse. A system, a method and a computer program product are also disclosed. The radiation detection device comprises an optical detector pixel array which has a plurality of pixel cells that can be triggered by optical photons, a plurality of pixel cell trigger state sensing circuits, and a summing unit. Each pixel cell trigger state sensing circuit generates a digital signal having either a first predetermined amplitude indicative of a triggered pixel cell, or a second predetermined amplitude indicative of a non-triggered pixel cell. The summing unit generates an analogue signal whose amplitude corresponds to the number of triggered pixel cells and thereby performs the desired integration. The analogue signal may further cause a timing unit to generate a timestamp when a predetermined accumulated optical photon count condition is met.

摘要： A method of performing a security inspection of a container including a plurality of objects includes irradiating the container with polychromatic x-rays. The method also includes reconstructing a 4-D voxelized representation defining a momentum transfer spectrum and generating a 3-D image by determining a single value at each voxel as a function of the momentum transfer spectrum. The method further includes segmenting the voxels into segments of contiguous voxels. Each segment includes a plurality of contiguous voxels that at least partially map onto at least one object. The method also includes computing an aggregated momentum transfer spectrum over at least a portion of the plurality of contiguous voxels. The method further includes classifying the aggregated momentum transfer spectrum as one of threat and non-threat and distinguishing the at least one object as one of a threat segment and a non-threat segment based on the aggregated momentum transfer spectrum.
