Abstract

The invention discloses a method and system for modulating tube current based on human body parts. According to the method and the system for modulating tube current based on the human body parts, a first ray path length and a first position information of each part of a human body are determined through a human body plain film of a patient to be detected, then a tube current modulating model is adopted, and the tube current values of different parts of the human body can be determined according to the obtained ray path length and the position information of each part of the human body, so that accurate modulating and control of the tube current of different parts of the human body can be completed, and a clearer CT image can be generated while the CT shooting radiation quantity is reduced.

Description

technical field [0001] The invention relates to the technical field of tube current regulation, in particular to a method and system for modulating tube current based on human body parts. Background technique [0002] Different parts of the human body have different thicknesses and densities. Using the same tube current to scan may cause some problems. For thicker parts, the X-ray intensity under the tube current may be insufficient, and for thinner parts, the intensity may be too high. In order to meet the scanning requirements of different parts, reduce the overall scanning dose, and improve the imaging quality of each part, it is necessary to modulate the tube current. At present, the current modulation in the moving direction of the scanning bed is adjusted according to the attenuation value, which does not take into account the characteristics of scanning different organs, and the problem of relatively large CT image noise will actually occur. [0003] Therefore, ther...
