The invention provides a bed board motion control method and system, a CT scanning system and a storage medium. The bed board motion control method comprises the following steps of using a first motion instruction to control a bed board to move between a sampling starting position and a sampling ending position, and obtaining measured values of the bed board at a plurality of sampling points and an expected value of the first motion instruction; establishing an error compensation model according to the measured values and the expected value; generating a third motion instruction according to the error compensation model and a second motion instruction; and driving the bed board to move to the target position according to the third motion instruction. According to the bed board motion control method and system, the CT scanning system and the storage medium, the motion instruction is compensated through the error compensation model, the motion precision of the bed board can be improved, then the imaging quality is improved, operation is easy, and implementation is easy.
Description
technical field [0001] The invention relates to the technical field of error compensation of medical equipment, in particular to a bed board motion control method, system, CT scanning system and storage medium. Background technique [0002] CT (Computed Tomography), that is, electronic computer tomography, it uses precisely collimated X-ray beams, γ-rays, ultrasound, etc., together with highly sensitive detectors, to conduct cross-sectional scans one after another around a certain part of the human body. It has the characteristics of fast scanning time and clear images, and can be used for the examination of various diseases. Helical scanning is one of CT scanning techniques. Because the scanning trajectory is helical, it is called helical scanning, also known as volume or volume scanning. see figure 1 , figure 1 It is a schematic diagram of the scanning process principle of the scanning imaging of the CT scanning system. The CT scanning system includes a frame 300, a be...
