[0005] According to the survey, the radiology department of the hospital has more than 40 GB of images after compression every day, about 10 TB a year, and medical images are generally required to be stored for 15 years. Generally, domestic hospitals use "online-nearline-offline" three-level storage mode, the storage mode of disk array and tape drive (or optical disc library) with commercial centralized storage as the core, and the storage mode of NAS, DAS, and SAN. It belongs to the centralized file system of a dedicated network. Good performance, but with the passage of time, the amount of data increases, the performance in expansion is poor, the cost of hardware equipment is also very high, and it is difficult to achieve sharing within the hospital or even in the region, and the flexibility is very poor

The invention relates to a distributed medical image data storage method based on a cloud platform, and the method comprises the following steps: designing a cloud storage architecture, and generating a local-cloud two-stage storage mode; according to a local-cloud two-stage storage mode, a distributed medical image storage architecture is constructed; the method comprises the following steps: constructing a ProxmoxVE virtual resource environment, and aiming at the access characteristics of massive medical image files, constructing Ngi nx on a cloud FastDFS; cloud FastDFS storage is optimized, and medical image data and metadata storage are generated. Through a local-cloud two-stage storage mode, a large-scale distributed medical image storage architecture is provided, a medical image cloud storage service aims at a special format D I COM and an application scene of a medical image, the problem of synchronous delay of storage nodes in a cluster is solved, and the cache hit rate and the access rate of the medical image are improved.
Description
technical field [0001] The invention relates to the technical field of big data, in particular to a method for storing distributed medical image data based on a cloud platform. Background technique [0002] With the popularization of information technology and Internet technology, people have entered the era of big data. Big data refers to the large amount and dimension of data, rich data forms, and a wide range of types, such as text, images, sounds, numbers and so on. [0003] At the same time as the introduction of information technology in the medical industry, the degree of informatization and automation in the medical industry has been continuously improved, and medical data has shown growth of terabytes or even petabytes. According to the statistical analysis of existing data, it is estimated that in 2020, medical data will increase sharply to 35ZB (1ZB=230TB), which is equivalent to 44 times the amount of data in 2009. It was authoritatively released by the China Hea...
