    摘要： A method is described for the combined processing of spectral data from a plurality of radiation detectors (4,6), in particular with a plurality of response functions, comprising: obtaining a response matrix for each detector (4,6); collecting data from radiation incident at each detector (4,6); producing a spectral histogram for the collected data from each detector (4,6); deconvoluting the histograms from each detector by applying a suitable numerical deconvolution such as a Bayesian deconvolution that makes use of the response matrix for each detector to derive a single spectral histogram that representatively combines information from the plurality of detectors. An apparatus, such as a hybrid detector apparatus, to which the method can be applied is also described.

    摘要： A method and system for facilitating the identification and/ or authentication of objects, and to a method and system for the marking of objects with an identity and/ or as of authentic origin, anda set of objects marked to facilitate subsequent identification and/ or authentication are described. The marking comprises incorporating into an object or part thereof or onto a tag mechanically engaged therewith a marker material exhibiting a characteristic radiation interaction response to incident high- energy ionizing radiation from a test source that is known to vary spectroscopically across the spectrum of the source. The presence or otherwise of the marker material may be determined by subsequent interrogation of an object with a suitable radiation source and detector to infer whether an object is of marked identity or origin.

    摘要： Method for the identification of a homogeneous material (e.g. a liquid) in a container (e.g. a bottle) by measuring its X-ray or gamma spectrum and deriving its specific attenuation function. The method comprises building a database of the attenuation functions of empty containers, of containers filled with various fluid materials and of the contained fluid materials itself (by subtracting or devoluting the empty-container-attenuation-function from the filled-container-attenuation-function), recording the spectrum of an unknown material in a container and comparing this spectrum to the spectra in the database.

    摘要： A radiation detector device is described comprising a detection module, a processing module, and a display module, wherein the detection module includes a detector adapted to detect incident radiation in spectroscopically resolved manner in plural separate energy bands; the processing module is adapted to process the spectroscopically resolved data numerically and thereby to produce at least a first data item indicative of a measure of radiation incident at the detector and a second data item indicative of a statistical certainty applicable to the first data item; the display module is adapted to produce a display representative of both the first data item and the second data item. A radiation detection method, a kit of parts for implementing the same for example in combination with a suitable programmable device, and associated concepts, are also described.

    摘要： A method processing an image dataset of radiation emergent from a test object after its irradiation by a suitable radiation source is described which comprises the steps of: generating an image dataset comprising a spatially resolved map of items of intensity data from the radiation emergent from the test object; further, resolving the intensity data items spectroscopically between at least two energy bands across the spectrum of the source; numerically processing the spectroscopically resolved intensity data items to determine a further spatially resolved dataset of data items representative of one or more orders of Compound Proton Number and/or effective mass thickness and/or a density; generating a segmented image dataset using the said dataset of data items representative of one or more orders of Compound Proton Number and/or effective mass thickness and/or a density. The method applied as part of a method for the radiological examination of an object and an apparatus for the same are also described.

    摘要： A method and apparatus for correction of detected radiation data from a semiconductor device are described. The method comprising the steps of measuring a pulse energy reading from radiation incident at the semiconductor device; filtering the signal and determining the time that the filtered signal exceeds a predetermined threshold energy; if the determined time is within predetermined parameter(s) comprising at least a predetermined maximum, storing the pulse energy reading in a first, pulse energy data register; if the determined time is above a predetermined maximum, discarding the pulse energy reading and incrementing a count in a second, discard data register; repeating the above steps to acquire a dataset of pulse energy readings of a desired size in the first data register; and on completion of such acquisition; using the discard data register to supplement the dataset of pulse energy readings by numerically correcting discarded counts and adding back into the dataset of pulse energy readings.
