    摘要: The present invention relates to a metal-organic hybrid lattice material and the application in the detection of radiation sources. In the invention, a water-soluble thorium salt and 2,2′:6′,2′-terpyridine-4′-carboxylic acid are subjected to a solvothermal reaction in water and an organic mixed solvent to obtain a metal-organic hybrid lattice material. The crystalline material produces radiation-induced discoloration and photoluminescence change under ultraviolet light, X-ray, γ-ray, β-ray, and so on. The material is useful for qualitative and quantitative detection and calibration after high-dose irradiation. Compared with the traditional radiation-induced color change indicator labels, the material achieves the visual qualitative and quantitative detection and has strong radiation stability, high reuse rate, wide detection range, and good linear relationship, to solve the problem of traditional materials relying on professional optical equipment to quantify the radiation dose.

    摘要: The invention relates to a system (1) for detecting image parameters during the exposure of films (2), in particular X-ray films. It is an object of the invention to provide a system which allows a simple and fast production of optimally exposed recordings. For this purpose, the system (1) comprises a detector element (3) which can be detachably attached to a film (2) and which detects in a spatially resolved manner the radiation (4) impinging on the film (2) during exposure or the radiation (4) transmitted through the film and thereby generates a signal from which image parameters generated by the current film exposure can be derived.

    摘要: A method of beamforming datasets from a tomographic detection system. The system comprises scintillation detectors that are arranged in D detector pairs, D≥1, wherein the detectors are adapted to count radiation hits. According to the method in one aspect, a tomographic dataset is received for each detector pair coordinates (θd, pd) of a detector pair d of the D detector pairs, so as to obtain a plurality of tomographic datasets. Each of said datasets is associated with respective detector pair coordinates (θd, pd). Then, for each point y of interest, the received datasets are coherently combined by weighting the datasets according to respective beamforming weights d(y)=ω(θd, pd; y), based on said respective detector pair coordinates (θd, pd) and coordinates of said each pointy of interest. This way, a signal focusing on said each pointy is obtained. Related tomographic detection systems and computer program products may be also presented.
