摘要： A portable radiological cassette is designed to equip a digital radiological system. The cassette comprises a digital ionizing radiation detector in the form of a flat panel which makes it possible to provide an image which depends on the radiation received, with an electronic board ensuring the control of the digital detector, and a casing ensuring the mechanical protection of the detector and the electronic board. The cassette additionally comprises a flat seating which supports the detector on a first one of its main faces, and supports the electronic board on a second one of its main faces, the two main faces being opposite. The seating is formed by a heterogeneous stack produced such that the surface thermal conductivity of the seating is greater than the transverse thermal conductivity of the seating.

摘要： A photon-counting detector includes a first subset of detector modules and at least one second subset of detector modules. Each detector module has power-consuming circuitry. Power-consuming circuitry of detector modules in the first subset is configured, in an operational mode in which the detector modules are powered on, to consume a first amount of power. Correspondingly, power-consuming circuitry of detector modules in the at least one second subset is configured, in the operational mode, to consume a second amount of power that is lower than the first amount of power.

摘要： A gantry includes two X-ray source rings and a detector ring. Each X-ray source ring includes a plurality of X-ray sources arrayed circumferentially. The detector ring is provided next to the X-ray source ring and includes a plurality of X-ray detectors arrayed circumferentially. Each of the plurality of X-ray detectors detects X-rays from the X-ray source ring. A data collection circuit collects raw data corresponding to the intensity of the detected X-rays. A reconstruction unit reconstructs the collected raw data into a CT image based on digital data.
