Abstract

The invention provides an X-ray source scanning parameter adjustment method. The method comprises the steps that X-ray source scanning parameters are obtained, wherein the X-ray source scanning parameters comprise a rotation period of a target disk and an energy period of an X-ray source; the ratio of the rotation period to the energy period is determined; if the ratio does not satisfy a preset condition, the X-ray source scanning parameters are adjusted, so that the ratio satisfies the preset condition; the preset condition is a first preset condition or a second preset condition, wherein thefirst preset condition is that the ratio of the rotation period to the energy period is not equal to an integer, and the second preset condition is that the ratio of the rotation period to the energyperiod is equal to a half integer. The provided X-ray source scanning parameter adjustment method has the advantages that by adjusting the rotation period of an anode target disk and the energy cycleof the X-ray source, the rotation period of the anode target disk is not an integral multiple of the energy period of the X-ray source, thereby avoiding the occurrence of an 'anode target disk energybeat frequency phenomenon', reducing the thermal deformation of the anode target disk, and prolonging the service life of the anode target disk.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a method, device, computer equipment and readable storage medium for adjusting X-ray source scanning parameters. Background technique [0002] Dual-energy computerized tomography (Computed Tomography, CT) can use the different absorption characteristics of X-rays at different energy levels to analyze the composition of substances, thereby improving its ability to visualize soft tissues, and has very high clinical application value. As a kind of dual-energy CT, the fast kV switching of single-source CT has the advantages of simultaneous, homogenous, and same-direction compared with traditional dual-source CT, and is a dual-energy imaging method with excellent performance. [0003] The X-ray source mainly generates thermal electrons by heating the cathode filament, and uses the thermal electrons to bombard the anode target disk to generate X-rays. Since the output power of...
