Digital radial photography system bulb sport control device

Abstract

The invention discloses a bulb tube movement control unit used in a digital radiology photography system, comprising a bulb tube holding hoop, a bulb tube bracket and a horizontal rotating shaft which is arranged on the bulb tube bracket. The bulb tube holding hoop is fixedly connected with the horizontal rotating shaft; the bulb tube movement control unit also comprises a motor arranged on the bulb tube bracket; the motor is connected with the horizontal rotating shaft through an actuating mechanism; the motor drives the horizontal rotating shaft to rotate, thereby driving a bulb tube to rotate. The bulb tube movement control unit used in the digital radiology photography system drives a screw bevel gear mechanism through the motor arranged on the bulb tube bracket, realizes the automatic rotation of the bulb tube around the horizontal rotating shaft, and realizes the automatic tracking of the bulb tube rotating position through an encoder arranged on the bulb tube bracket; the relative position between a DR detector and the bulb tube does not need to be adjusted manually; therefore, the movement noise is eliminated, and the work intensity of doctors is reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a ball tube motion control device for a digital radiography system. Background technique [0002] like figure 1 and figure 2 As shown, the suspended digital radiography system consists of a tube 1 , a column 2 , a high-voltage generator, an image acquisition workstation, an imaging bed 3 , and a DR (Digital Radiography, digital radiography) detector 4 . The tube 1 is installed on the tube hanger 5 through the tube bracket 6, the tube is installed in the tube hoop 7, the tube rotates around the vertical axis 8 and the horizontal axis 9, and can be hung with the tube The telescopic cylinder of frame 5 carries out lifting motion together. The column 2 is installed and fixed on the floor of the machine room, and a DR detector 4 is installed on it. The DR detector 4 can rotate around a horizontal axis, and can also move up and down along the column 2 . The photography b...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a tube motion control device for a digital radiography system, which overcomes the need for an electromagnetic device with a large magnetic force when the tube of a suspended digital radiography system in the prior art is manually rotated around a horizontal axis of rotation. The position of the brake is controlled, which is prone to suction noise and the defect that the relative position between the DR detector and the ball tube needs to be manually adjusted
