Data transmission device based on plane reflection in computer tomoscan imaging equipment

Abstract

The embodiment of the invention discloses a data transmission device based on plane reflection in computer tomoscan imaging equipment. The data transmission device comprises a light emitting module, a light reflection module and a light receiving module, wherein the light emitting module is arranged on a rotating body of the computer tomoscan imaging equipment, and is used for converting data information acquired by scanning the rotating body in the rotation process into a light signal and transmitting the light signal to a certain pivot point on the rotating shaft of the rotating body; the light reflection module and the light receiving module are arranged on a fixed body of the computer tomoscan imaging equipment; and the light receiving module is positioned at the pivot point, uses the reflective surface of the plane mirror surface as the mirror image position of the mirror surface, and is used for receiving the light signal reflected by the light reflection module. By utilizing the data transmission device, the data can be reliably transmitted from the rotating body to the fixed body, so that the data transmission process is stable and the data transmission speed is high.

Description

technical field [0001] The invention relates to the technical field of computed tomography imaging, in particular to a data transmission device based on plane reflection in computer tomography imaging equipment. Background technique [0002] At present, in the spiral computed tomography imaging system, how to quickly and reliably transmit the data collected by the rotating detector (rotating body) to the image processing unit (fixed body) outside the rotating body is a very important problem. Signal transmission in CT is accomplished by cables, but the limited length of cables limits the continuity and speed of scanning. [0003] The emergence of slip ring technology solves the above problems, enabling the scanning system to rotate continuously, which greatly improves the scanning speed. During the high-speed rotation of the traditional contact slip ring, the brush and the slip ring are in close contact, which will cause the brush to Abrasion produces a lot of dust particle...

Problems solved by technology

However, since the wireless capacitive coupling method uses the electromagnetic field to transmit signals, it is easily affected by external voltage, current, and electromagnetic fields, so it is greatly restricted and affected in terms of high-speed and large data transmission.
