CT image data acquisition method and device and computer equipment

Abstract

The invention discloses a CT image data acquisition method and device and computer equipment, and mainly aims at achieving the purpose of acquiring CT image data of at least two image data areas under respective data parameters through one-time scanning, so that the radiation frequency of a patient can be reduced, and the transmission efficiency of the CT image data and the real-time performance of CT scanning are improved. The method comprises the following steps: acquiring view edge position information and data parameters respectively corresponding to at least two image data areas; according to the view edge position information, determining detector edge position information corresponding to the at least two image data areas; and based on the detector edge position information and the data parameters, respectively extracting CT image data of the at least two image data areas under respective data parameters. The invention is suitable for acquiring the CT image data.

Description

technical field [0001] The present invention relates to the technical field of CT (Computed Tomography, electronic computer tomography), in particular to a method, device and computer equipment for acquiring CT image data. Background technique [0002] In the structure of CT, the data processing unit and the data transmission unit are used to process the data output by the X-ray detector, and transmit the processed data to the data receiving unit of the CT imaging system through the data transmission path. In the current CT equipment, when the data transmission path is certain, it is necessary to reduce the amount of transmitted CT image data as much as possible, thereby reducing the data transmission time, so as to meet the real-time requirements of CT scanning. [0003] At present, since doctors often pay attention to the image of a certain area in the CT image, rather than the complete CT image, the area that the doctor is concerned about can be set as an image data area ...

Problems solved by technology

However, in this method of setting a single image data area, only CT image data under one data parameter can be obtained in one scan. If CT image data under another data parameter needs to be obtained, another scan is required. , which will increase the radiation times of the patient. In addition, if the CT image data to be obtained comes from a discontinuous area, this method will lead to the expansion of the coverage of a single image data area, thereby increasing the transmission of unnecessary CT image data. As a result, the transmission efficiency of CT image data is low, and the real-time performance of CT scanning cannot be guaranteed.
