Abstract

A method and a system for data compression are provided. The method may include: obtaining scanning data to be compressed; compressing the scanning data using a first compression method and a second compression method to obtain a first compressed data and a second compressed data respectively, where a compression ratio of the first compressed data is lower than a compression ratio of the second compressed data; and determining whether the compression ratio of the first compressed data meets a predetermined compression ratio requirement, if yes, determining the first compressed data as a compression result data corresponding to the scanning data, if no, determining the second compressed data as a compression result data corresponding to the scanning data. Scanning data compressed by the method or the system can meet target compression requirements.

Description

technical field [0001] The invention relates to the field of medical data processing, in particular to a computer tomography CT data compression method and device. Background technique [0002] At present, in the medical field, CT (X-ray computed tomography) is more and more widely used. CT uses X-rays for tomographic scanning, uses detectors to receive, and converts the signal into digital input to the computer, and then the computer converts the digital A medical device transformed into an image. [0003] With more and more layers of CT scanning data, the amount of data collected by CT is also increasing, which makes the data collected by CT require larger transmission bandwidth and higher The transmission speed and so on, which puts more and more pressure on the data transmission link. [0004] Therefore, it is necessary to propose an effective technical solution for CT data compression, so as to reduce the technical problem of low data transmission efficiency caused by...
