Description

technical field

[0001] The invention belongs to the field of medical image processing, and in particular relates to a storage method and a use method based on an HDFS distributed file system. Background technique

[0002] With the rapid development of medical imaging technology, medical images have become an important basis for medical clinical diagnosis. These data are currently stored in the PACS (Picture Archiving and Communication System) system, using high-performance, large-capacity network storage arrays, tape libraries and other storage media. PACS follows the DICOM3.0 international standard, which is the organization and communication standard of medical images.

[0003] At present, the PACS system has gradually developed from a single machine and departments to the whole hospital and regions, realizing the film-free hospital. Regionalization is the current main research goal of government health departments and medical institutions, but building a large shared me...
