Abstract

The invention provides a method for acquiring a reconstruction parameter of a computed tomography image. A Realtime data package containing information, such as, a moment bulb angle, beds, and the like, is sent to a data reconstruction system through a rack control system at intervals, and the angle of de-spooling bulb rotation and / or the position of a bed are / is acquired by utilizing the Realtime data package to perform the interpolation calculus. According to the technical scheme provided by the invention, the precision of the acquired or calculated angle parameter of de-spooling bulb rotation and / or the position parameter of the bed is greatly increased.

Description

technical field [0001] The invention relates to the field of computerized tomography, in particular to a method for obtaining computerized tomography image reconstruction parameters. Background technique [0002] In the computed tomography system, it is necessary to measure the rotation angle of the tube and the position of the examination bed at each time of setting off the line. The rotation angle of the tube and the position of the examination bed have a great influence on the quality of the produced image, so it is necessary to improve these two The precision of a parameter. As mentioned in the patent "Projection Angle Acquisition Method and Device in Image Reconstruction" (Patent No. CN101327127), the speed measurement positions less than the number of pay-offs are set around the rotating frame of the CT frame, and at each preset The speed measurement position measures the running speed of the tube, and according to the measured running speed of the tube, determines th...
