Digitalization radiation shooting automatically tracing system

Abstract

The invention discloses a digital radiation photography automatic tracking system, including a power module, a first encoder module, a second encoder module, a controller module, a first motor driving module and a second motor driving module. The power module is used to supply DC voltage to the first encoder module, the second encoder module, the controller module, the first motor driving module and the second motor driving module. The first motor driving module is used to control the rotation of a column motor. The second motor driving module is used to control the rotation of a spherical pipe hanger. The first encoder module is used to output a first impulse signal into the controller module according to the rotation of the column motor. The second encoder module is used to output a second impulse signal into the controller module according to the rotation of the spherical pipe hanger. The controller module is used to output controlling signals to the first motor driving module according to the input command signals and the output controlling signals to the second motor driving module according to the comparison between the first impulse signal number and the second impulse signal number.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a DR (Digital Radiography, digital radiography) automatic tracking system. Background technique [0002] The DR photography system is mainly composed of the following parts: tube, tube hanger, column, high voltage generator, DR detector, image work collection station. The tube hanger is installed on the sky rail, and the tube is fixed at the lower end. The tube moves up and down vertically under the drive of the motor according to the needs of the patient and the photographed part; the column is installed on the ground to fix the DR detector, DR detector According to the needs of the patient and the site to be photographed, it can move up and down vertically under the drive of the motor. The high-voltage generator mainly provides high pressure with set parameters for the bulb, so that the bulb emits X-rays of required dose. The image workstation reconstructs the image...
