CT image chain recombination method based on separation of scanning front end and imaging rear end

Abstract

The invention relates to a CT image chain recombination method based on separation of a scanning front end and an imaging rear end. Rays are given out by a bulb tube of a front end scanning system, and then pass through a to-be-detected part of the human body; after the to-be-detected part of the human body is scanned, a probe of the front end scanning system receives the rays passing through the human body; additional information is loaded on data received by a probe module, stored in storage equipment in real time, and is not subjected to beforehand preprocessing; the data is sent to a far end computer after entire scanning is completed; the computer restores the whole scanning process by analyzing the transmitted data; a rear end distributed processing method is utilized to execute reconstruction and after-treatment steps which are also executed on a traditional image chain. According to the CT image chain recombination method based on the separation of the scanning front end and the imaging rear end, the scanning front end of CT and the imaging rear end are totally dismantled, only scanning equipment faces a user, so that the user simply conducts conventional scanning work according to an operating instruction, the later processing work is delivered to technicists of a cloud side, the CT size is reduced, the cost is lowered, and data processing and analyzing are facilitated and simplified.

Description

technical field [0001] The invention relates to a CT image processing technology, in particular to a CT image chain recombination method based on the separation of the scanning front end and the imaging rear end. Background technique [0002] At present, the CTs used in mainstream hospitals are highly integrated large-scale medical equipment. Every link is interlocking and highly dependent on each other. The formation of the image chain of mainstream equipment can be summarized as the following steps, such as figure 1 Shown: 1) The ball tube emits rays, which pass through the parts of the human body to be detected, and the detector receives the rays passing through the human body; 2) The detector converts the received rays into electrical signals, and then converts them into digital signals through an analog-to-digital converter; 3) The data is preprocessed and corrected in real time, and transmitted to the computer; 4) Input to the computer contained in the CT machine bas...
