Abstract

The invention relates to a method and device for measuring effective energy of a scanning imaging system and the scanning imaging system.The scanning imaging system effective energy measuring method comprises the steps that a spectral response curve of a photon counting detector to X-rays is determined, the X-rays are from an X-ray source of the scanning imaging system, the spectral response curve is used for representing distribution conditions of photons under different energies; a preset energy bin and a threshold range of the energy bin are determined; the effective energy of the energy bin is calculated according to the threshold value range of the energy bin and the spectral response curve of the photon counting detector to the X rays, and the effective energy is used for determining the mass attenuation coefficient of the base substance. According to the method and the device, the problem of relatively low calculation accuracy of the effective energy caused by calculation of the effective energy through an energy integral detector in related arts is solved, the calculation accuracy of the effective energy of the energy bin is improved, and meanwhile, the calculation efficiency is also improved.

Description

technical field [0001] The present application relates to the field of scanning imaging, in particular to a method, device and scanning imaging system for measuring the effective energy of the scanning imaging system. Background technique [0002] A scanning imaging system for imaging based on X-rays includes an X-ray source and an X-ray detector, wherein the X-ray source is used to emit X-rays, and the X-ray detector is used to obtain X-rays passing through a scanned object. Since different substances absorb X-rays differently, the body part of the scanning object can be scanned based on the X-rays to determine whether there is an abnormality in the body part of the scanning object. [0003] In related technologies, X-ray detectors are usually energy-integrating detectors. Energy-integrating detectors use 99% pure aluminum balls to perform tomographic imaging experiments and compare them with theoretically calculated values ​​to determine the X-ray intensity in the scanning...
