Abstract:
1. A method for reducing a share of scatter radiation in detector data obtained with detectors arranged at an angle offset and opposite-arranged X-ray radiators of a multi-radiator computed tomography (CT) system, wherein the X-ray radiators are configured to transmit X-ray radiation with a first energy spectrum onto a measuring object, and the measuring object emits scatter radiation with a second energy spectrum, the method comprising: determining the first energy spectrum of the X-ray radiation transmitted by an X-ray radiator; computing the second energy spectrum of the scatter radiation emitted by the measuring object based on a Compton scattering; energy-selective measuring of X-ray radiation impinging on the detectors; separating the measured X-ray radiation into at least two energy bins; allocating the measured x-ray radiation to transmitted or respectively scattered radiation according to the separated at least two energy bins; and exclusively using detector data assigned to the transmitted X-ray radiation for imaging; wherein
