Multi-magnification digital slice image storage and browsing method and system

Abstract

The invention discloses a multi-magnification digital slice image storage and browsing method and system. The whole digital slice image is divided into a plurality of tile images with small sizes, andthe position and the layout of the tile images are described by utilizing longitude and latitude coordinates, and the longitude and latitude coordinates are converted into paths and file names storedby the image files through map projection transformation, and the multi-magnification digital slice image organization and storage can be realized. The multi-magnification digital slice image storageand browsing system based on the method comprises a metadata read-write module, a file directory management module, a tile image read-write module, a scanning map read-write module and a label imageread-write module, a preview image read-write module, a longitude and latitude coordinate and image path analysis module, a digital slice reconstruction and browsing module and a file system. The method has good universality, and is convenient and rapid in retrieving and positioning are convenient and rapid, and is suitable for large-scale concurrent access of digital slices.

Description

technical field [0001] The invention belongs to the field of digital slicing, and in particular relates to a method and system for storing and browsing multi-magnification digital slicing images. The invention is used for standardized splitting, storage and browsing of digital slice images produced by different scanning devices. Background technique [0002] Pathological examination of diseases is the gold standard for disease diagnosis. At present, the pathological diagnosis of tumors, especially malignant tumors, is regarded as a sentencing and authoritative diagnosis. However, pathological diagnosis is not absolutely authoritative, nor is it omnipotent. Like other disciplines, it has its inherent subjective and objective limitations. The accuracy of pathological diagnosis depends heavily on the professional level and work experience of pathologists, and diagnostic conclusions are often highly subjective and one-sided. It has been reported that the inconsistency rate of...
