Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] figure 1 It is a flow chart of the method for CT data acquisition and virtual reproduction of the scanning process in this embodiment, and the method includes processing steps at the scanning system end and processing steps at the post-processing end.

[0026] The processing steps on the scanning system side are described in steps 1 to 4.

[0027] Step 1. Before CT enters the scanning stage, when the scanning system receives the scanning request sent by the computer or server, it records the total number of scanning angles, the distance from the radiation source to the rotation center, the distance from the radiation source to the detector, the distance from the ro...

Abstract

The invention provides a method for CT data acquisition and virtual reproduction of the scanning process, and relates to the technical field of computed tomography imaging. The method includes processing on the scanning system side and processing on the post-processing side. When the scanning system receives the request scanning instruction from the post-processing side, it records fixed parameter information, geometric parameter information and photon information at each scanning angle, and establishes corresponding data files. , a request is sent to the post-processing end. After receiving the request instruction, the post-processing end begins to receive the file. After verifying that it is correct, it begins to parse, synthesize the acquired data, draw the scanning system framework, and form a dynamic playback of the final scanning process. The method of CT data acquisition and virtual reproduction of the scanning process provided by the present invention can realize dynamic playback of the entire scanning process by counting photons one by one, effectively reducing the number of multi-energy CT scans and reducing the radiation dose.

Description

technical field [0001] The invention relates to the technical field of computerized tomography, in particular to a method for CT data collection and scanning process virtual reproduction. Background technique [0002] Computed Tomography (CT) is one of the most advanced large-scale medical diagnostic imaging devices recognized in the current medical field. In terms of the general structure of various forms of CT, CT is composed of detectors, X-ray tubes and coincident systems, computer or server systems, etc. The tube of CT emits X-rays through the object to be tested, and the detector receives the attenuated X-ray signals. After being processed by the scanning system, the scanned data is stored, and finally the scanned data is called by the computer for image reconstruction. A cross-section image of the object to be tested is obtained. [0003] Usually, in the traditional acquisition method of CT, the scanning system only acquires and outputs the final data obtained at ea...
