Angle-adjustable CT (Computed Tomography) device

Abstract

The invention discloses an angle-adjustable CT (Computed Tomography) device and belongs to the technical field of computer tomography equipment. The device comprises a suction cup matrix and a drive part, wherein the suction cup matrix adsorbs and fixes a to-be-detected object; the drive part is composed of a plurality of drive units connected in series; each of the drive units is composed of an electromagnetic actuator, a rotating part, an upper platform and a lower platform; the electromagnetic actuator and the rotating part are in one-to-one association and are evenly placed between the upper platform and the lower platform; the rotating part is formed by connecting a rotating body, a cross shaft, a connecting shaft and a nut; the rotating part has a universal rotating function; a strong magnet is fixed at the bottom of the lower platform; and the bottom of the lower platform is fixed on a CT turntable through the strong magnet. According to the angle-adjustable CT device, by controlling the movement of the drive units, the angle adjustment of the to-be-detected object is implemented, the adjustment angle is large, the adjustment efficiency is high, the device can be repeatedlyused, the efficiency of CT detection is improved, the manual repeated change of the angle of the to-be-detected object is prevented, the labor intensity of an inspector is reduced and the device has good promotion and application values.

Problems solved by technology

However, the above-mentioned CT structure can only roughly adjust the positions of the X-ray source and the flat panel detector relative to the platform synchronously, and lacks an independent mechanism capable of adjusting the three-dimensional angles of the flat panel detector and the X-ray source, thus making it impossible to precisely adjust the X-ray source The line connecting the focal point and the center point of the flat-panel detector is perpendicular to the imaging surface of the flat-panel detector, resulting in poor reconstruction image quality
