Dental department CT three-dimensional imaging synchronous control method and device based on embedded software

Abstract

The invention relates to a dental department CT three-dimensional imaging synchronous control method and device based on embedded software, and belongs to the technical field of medical equipment. The method and device are characterized in that the device comprises a man-machine interaction unit and a lower computer system; the method includes the three implementation steps that firstly, a user adjusts exposure parameters through the man-machine interaction unit, and a rotary cross arm is reset to an initial motion position; secondly, slow lifting, stable motion, slow stop motion and real-time position display of the rotary cross arm are achieved in the exposure process; thirdly, synchronous control over rays in the motion process is achieved. The method and device have the advantages that a man-machine interface based on the embedded software is visual in operation and easy and convenient to operate, synchronous control and accurate positioning of the rays are achieved according to the real-time motion position, the integration level is high, and an optimal image is generated through the radiation dosage with the least likelihood.

Description

technical field [0001] The invention belongs to the technical field of medical equipment. Background technique [0002] At present, with the widespread use of dental CT in clinical stomatology, its characteristics of high resolution, accurate positioning, clear images, and avoiding overlapping will surely enable the diagnosis and treatment of stomatology to achieve in-depth development, bringing good news to doctors and patients Dental CT requires high-precision mechanical structure, because its scanning trajectory, trajectory radius, scanning speed and other geometric parameters are different, and it is necessary to add pulse control signals of rays, synchronization signals of cameras, and movement in a short exposure process. Speed, motion position control, etc., the process is complex, high precision, and high real-time; traditional control devices separate the motion and radiation control units, or use improper synchronous control methods, resulting in patients being irr...
