Digital slide storage system and digital slide browsing method

Abstract

The invention discloses a digital slide storage system. The digital slide storage system comprises a metadata storage module used for storing metadata, and providing writing and reading interfaces of the metadata; an image storage module used for storing slide image data; a slide reconstruction module connected with the image storage module and used for cutting image layers under various magnifications into a plurality of small slide images in a specific patch size; a transmission module connected with the image storage module and the metadata storage module and used for reading slide metadata and image data of different manufacturers, and transmitting the slide metadata and image data to corresponding storage modules; and a browsing module connected with the image storage module and the metadata storage module and used for acquiring and displaying the slide images. The invention further comprises a digital slide browsing method based on the digital slide storage system. The digital slide storage system and the digital slide browsing method provided by the invention can efficiently store digital slides, and can realize instant browsing of the digital slides.

Description

technical field [0001] The invention relates to the field of digital slice storage, in particular to a digital slice storage system and a digital slice browsing method. Background technique [0002] In today's era of big data, more and more information is being digitized for easy computer retrieval, browsing, and analysis. Microscope slides are likewise digitized, consisting mainly of binary image data and metadata. The image data includes binary data at multiple resolutions. Metadata includes slice scanning information, storage format, patient-related information, etc. Traditional digital slices are stored in units of slices, and image data is layered in image pyramids (the structure is shown in the attached figure 1 shown) store, where figure 1 Among them, 101 is the bottom layer slice image, 102 is the high resolution bottom layer image, 103 is the viewing image area, 104 is the intermediate magnification image of the medium resolution, 105 is the intermediate magnifi...

AI Technical Summary

Problems solved by technology

[0003] 1) When querying and filtering slice metadata, it is necessary to open each slice file separately to read the metadata, which is inefficient and prone to errors during concurrent access;

[0004] 2) When multiple people browse the same slice, they will access the same file at the same time, and the hotspot data is too concentrated, which may easily cause performance bottlenecks;

[0005] 3) There is a single point of failure, if the file is partially damaged, it usually makes the entire slice content unreadable;

[0006] 4) It is necessary to solve the problem of data backup, in case the disk or file is damaged, resulting in data loss;

[0007] 5) Since the file is stored in slices, it cannot be used before the file transfer is complete;

[0008] 6) The slice formats of different manufacturers are different, and can only be stored separately, and cannot be used in a unified interface;

[0009] 7) The convenience of high concurrency, high reliability, and scalability brought by the new object storage system cannot be adopted
