Abstract

The invention discloses a method and device for modulating radiation dose, relates to the technical field of data, and mainly aims to solve the problem of poor modulation accuracy of the existing CT dose. The method comprises the following steps: acquiring first attenuation information of a determined shape filter and a plain film radiation dose of at least one section in a plain film scanning image; after starting radiation to scan a target area based on the plain film radiation dosage, determining third attenuation information expected to be generated by non-starting radiation at the target radiation position based on second attenuation information generated by starting radiation at the determined radiation position; and correcting the third attenuation information based on the equivalent diameter information and the first attenuation information, and determining the radiation dose corresponding to the radiation at the target radiation position according to the obtained fourth attenuation information after correction and the plain film radiation dose. The method is mainly used for radiation dose modulation.

Description

Technical field [0001] The present invention relates to the field of data technology, and more particularly to a modulation method and apparatus for radiation doses. Background technique [0002] With the continuous development of medical technology, CT (Computed Tomography), that is, electronic computer fault scanning, due to its ability to scan, imaging, etc., has been widely used in clinical medical scanning and detection. Among them, CT radiation dose modulation scanning techniques refer to a technique of continuously adjusting the scanning dose based on different patients, different scanning areas, and different scanning positions during the scanning process. [0003] At present, the existing CT dose modulation usually estimates the size of the scanned position according to the attenuation information of the known scanning position and the decay information speculating the resulting scan position, and the appropriate scanner is set, but the appropriate scanner is set, but wh...
