A method and system for intelligently assisted reading of cervical liquid-based cytology

Abstract

The invention provides a cytological intelligent auxiliary reading method and system for a cervical fluid-based slide, and belongs to the technical field of medical image processing. The cytological intelligent auxiliary reading method comprises: performing full-slide scanning, acquiring single-sheet full-slide digital microscopic image; performing recognition and classification on the full-slidedigital image, labeling a pathological cell region and an overlapping cell region as suspicious labeling area, generating a search region centered on the suspicious labeling area; moving the slides tosend the search region into an imaging view field one by one, performing multi-dimensional three-dimensional imaging. The system provided by the invention comprises an electrically controlled two-dimensional loading platform, a Z-axis moving unit, a slide code reading unit, a microscope, an imaging unit, three-dimensional imaging, and sending the imaging results to an image processing console. The cytological intelligent auxiliary reading method and system only perform multi-dimensional imaging on pre-selected search regions, not only provides complete 3D information, but also greatly reducesthe total imaging time of each slide, a pathologist has no need to browse the whole slide and search the pathological cells, therefore the reading efficiency is improved.

Description

technical field [0001] The invention relates to the field of microscopic imaging and intelligent identification of pathological slices, in particular to an intelligent auxiliary film reading method and system for liquid-based cervical cytology. Background technique [0002] Cervical liquid-based cytopathological examination is an important method for cervical cancer screening. Traditionally, cervical liquid-based cytopathology slides have been examined and reviewed under a microscope by a pathologist. Since the pathological slide area is much larger than the microscope imaging field of view, the inspection of a cervical liquid-based cell slide is relatively time-consuming, and the review of the lesion area after the inspection requires almost the same effort to find the area where the lesion cells are located. . [0003] In order to improve the efficiency of cytopathological examination, it is possible to scan and digitize the whole slide of cytopathology, and then use the...

AI Technical Summary

Problems solved by technology

When a pathologist is required to conduct a review, because the digital image of the whole slide scan has only a single two-dimensional plane information, it is difficult to obtain more information on some cell overlapping areas and some suspected lesion areas that are difficult to judge from the digital image alone. Image information also needs to be reviewed under a microscope

Moreover, there is no organic connection between the digitized image of the slide and the review under the microscope, so it is difficult to provide convenience and comparison for the review under the microscope
