| titleOfInvention | Parameter calibration method, device, and system for x-ray machine |
| abstract | A parameter calibration method, device, and system for an X-ray machine. The method comprises: controlling a rotating arm of an X-ray machine to rotate about and scan a standard phantom, and acquiring projection results of the standard phantom at multiple preset rotation positions (S110); recording, at each of the preset rotation positions, a mechanical structure motion state of the rotating arm (S120); calibrating, at each of the preset rotation positions and according to the projection results of the standard phantom, an error parameter to obtain a calibration result of the error parameter (S130); and generating, according to the mechanical structure motion state of the rotating arm at each of the preset rotation positions and the calibration result of the error parameter, a dynamic correction matrix for correcting an actual project result of the X-ray machine (S140). |
