Data transmission link and data transmission method for simplifying CT (computer tomography) system by utilizing caching

Abstract

The invention provides a data transmission link and a data transmission method for simplifying a CT (computer tomography) system by utilizing caching. The data transmission link comprises a ray tube, a detector, an image reconstructing system and a data transmission link, wherein the ray tube is used for generating an X-ray beam which is radiated on the detector after being attenuated through a detecting target; the detector is used for acquiring X-rays and converting the X-rays into data information, and transmitting the data information to the image reconstructing system; the image reconstructing system is used for performing image re-constructing on data transmitted back by the detector to obtain images as detected results; the data transmission link is used for transmitting data to the image re-constructing system through the detector. The data transmission link disclosed by the invention consists of a plurality of sections of transmission paths of different media, such as a rotary link and a fixed chain. According to the technical scheme adopted by the invention, 5G bps data link can be utilized to support system application with demands up to 50G bps.

Description

technical field [0001] The invention relates to a data acquisition and transmission link of a CT system and a data transmission method thereof, in particular to simplifying the data acquisition and transmission link of a multi-layer CT system by adopting a cache structure. Background technique [0002] Computed Tomography (CT system for short) is an imaging method completely different from traditional radiation imaging. Traditional radiation imaging is to project a three-dimensional object onto a two-dimensional plane for imaging. The projected images of each layer overlap and easily interfere with each other, which makes the imaging image blurred and loses a lot of depth information. [0003] The CT system scans a certain layer of the human body through an X-ray tube, and measures the data of X-ray absorption at each point in this layer, that is, the attenuation coefficient of X-rays. Then use the high-speed computing power of the computer and the principle of image recons...
