Description

technical field [0001] Embodiments of the present invention relate to the technical field of X-ray imaging, and in particular, to an energy imaging method, apparatus, device, and storage medium. Background technique [0002] With the diversified development of medical imaging technology, the density images of voxels obtained based on conventional electronic computed tomography technology have been unable to meet the medical application requirements of material distinction. On this basis, energy imaging technology based on rapid switching of tube voltages that can realize voxel material distinction emerges as the times require. This energy imaging technology can achieve simultaneous homologous and codirectional data domain energy imaging by rapidly switching the tube voltage between high energy voltage and low energy voltage, which is a very attractive energy imaging technology. [0003] In this energy imaging process, the ideal switching waveform of the tube voltage should ...
