摘要： Systems and methods are provided for detecting gaps in composite parts. One method includes radiating a beam of x-rays in a firing direction towards surface of a multi-layer Carbon Fiber Reinforced Polymer (CFRP) part, acquiring data indicating intensity of sidescatter radiation received at an x-ray detector that extends along the CFRP part in the firing direction, and examining the acquired data for gaps at the CFRP part based on differences in intensity indicated by the data.

摘要： A method for analyzing an object includes irradiating the object with incident photon radiation and acquiring an energy spectrum scattered by the material using a spectrometric detector in scatter mode. An energy spectrum transmitted by the material is acquired using a spectrometric detector in transmission mode. A signature (f) is reconstructed representing the object, both from the scatter spectrum measured and from the transmission spectrum measured, and the reconstructed signature thereof is compared with signatures of standard materials.

摘要： The invention provides methods and apparatus for enhanced PCI and dual-use radiation imaging systems. In one implementation high resolution storage phosphor plate radiation detector (an area detector) is employed for conventional attenuation radiation imaging and/or PCI (including conventional PCI and coded aperture PCI). Slit and slot scan implementations for dual-use systems are introduced. Dedicated single and dual-use slit and slot scan system for conventional attenuation imaging and PCI are described that employ face-on or edge-on detectors. Slit and slot scan systems that employ area detectors are described. Edge-on, structured cell detector designs are described. Applications of edge-on structured cell detectors for CT, Nuclear Medicine, PET, and probe detectors are described.

摘要： According to on embodiment, a photon counting CT apparatus includes a hybrid detector and processing circuitry. The hybrid detector includes CT detectors and PCCT detectors. The CT detectors output integral signals concerning the detected X-rays. The PCCT detectors output a count signal for each of a plurality of energy bands concerning the detected X-rays. The processing circuitry estimate a count signal concerning an estimation target CT detector of the CT detectors based on an integral signal output from the estimation target CT detector and a count signal output from the PCCT detector. And the processing circuitry reconstruct an image based on the estimated count signal and the count signal.
