Abstract

Embodiments of the invention disclose an X-ray tube position estimation method, device and system for X-ray imaging. The method comprises the following steps of detecting an acceleration value of an X-ray tube in the height direction based on a predetermined time interval; detecting a height value between the X-ray tube and a reference surface arranged in the height direction based on the time interval; and estimating a height estimation value of the X-ray tube between a predetermined time point and the reference surface based on the time interval, the acceleration value detected at the predetermined time point and the height value detected at the predetermined time point. An absolute position encoder can be omitted, high-precision estimation of the position of the X-ray tube can be achieved with low cost, and mechanical connection with a driving motor is reduced.

Description

technical field [0001] The present invention relates to the technical field of X-ray imaging, in particular to an X-ray tube position estimation method, device and system for X-ray imaging. Background technique [0002] X-rays are electromagnetic radiation with wavelengths between ultraviolet and gamma rays. X-rays are penetrating and have different penetrating abilities to substances of different densities. In medicine, X-rays are generally used to project human organs and bones to form medical images. Direct digital radiography (Digital Radiology, DR) technology has the characteristics of fast imaging speed, convenient operation and high imaging resolution, and has become the dominant direction of X-ray radiography. The detection object can stand near the chest X-ray frame assembly or lie on the examination bed assembly, so as to receive X-ray photography of various parts of the human body such as the head, chest, abdomen and joints. The X-ray tube uses the high voltage...
