Abstract

The invention provides an automatic slice reading method and an automatic slice reading system for PD-L1 antibody staining slices. The automatic slice reading of PD-L1 immunohistochemical staining slices is realized based on medical digital image analysis and processing. Specifically, the method disclosed by the invention comprises the following steps: preprocessing a PD-L1 dyed digital slice image; obtaining an image to be analyzed, inputting the to-be-analyzed image into a pre-established prediction model; obtaining a target area corresponding to set cells in the to-be-analyzed image; and carrying out image analysis on the cell image of each set cell in the target area, identifying the total number of cells in the target area and the number of cells with positive slice formation, obtaining the proportion of the cells with positive slice formation in the target area, and finally realizing rapid, accurate and automatic slice reading of the set cells.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, in particular, to an automatic reading method and system for PD-L1 antibody stained sections based on medical digital image analysis and processing. Background technique [0002] With the rise of immunotherapy, corresponding drugs have been produced targeting PD-L1 protein in the immune signaling pathway, such as Atezolizumab, Pembrolizumab, Nivolumab, etc. While improving the therapeutic effect, higher requirements are put forward for the quantitative analysis of PD-L1 immunohistochemically stained sections. At present, the quantitative analysis of PD-L1 immunohistochemical staining sections is mainly carried out manually, which requires a large amount of labor for doctors to read the slides and is inconvenient to implement. Contents of the invention [0003] The present disclosure provides an automatic reading method and system for PD-L1 antibody stained sections. [0004] ...
