Cervix uteri abnormal cell detection device and method

Abstract

The invention relates to the field of medical science and technology, and particularly discloses a cervix uteri abnormal cell detection device and method. The device comprises: an acquisition module for acquiring a cervical cell pathological slide image; a segmentation module for segmenting the cervix uteri cell pathological slide image into a plurality of cervix uteri cell pathological slide image blocks; a preprocessing module for preprocessing each cervix uteri cell pathological slide image block to obtain a plurality of target cervix uteri cell pathological slide image blocks; a processingmodule for processing each target cervix uteri cell pathological slide image block to obtain cervix uteri cell features, wherein the cervix uteri cell features are obtained through weighted fusion ofbidirectional features from high-order features to low-order features and from low-order features to high-order features of cervix uteri cells; and a determination module for determining the abnormalprobability of the cervical cells in the cervical cell pathological slide image according to the cervical cell characteristics. The embodiment of the invention is beneficial to improving the detection precision of the cervical abnormal cells.

Description

technical field [0001] The present application relates to the field of medical science and technology, in particular to a device and method for detecting abnormal cervical cells. Background technique [0002] Cervical cancer is one of the malignant tumors that seriously endanger women's lives and health, and its incidence rate ranks second among female malignant tumors. Moreover, cervical cancer is currently the only cancer that can be detected and cured early, so early screening is crucial for the treatment of cervical cancer. [0003] Cervical liquid-based cytology is currently the most commonly used method for cervical cancer screening. However, due to the lack of pathologists and cytology testing equipment, the general screening rate for cervical cancer is very low, so various intelligent auxiliary screening equipment systems are gradually emerging. However, most of the current intelligent auxiliary screening systems for cervical cancer have low detection accuracy for a...

AI Technical Summary

Problems solved by technology

Some of the abnormal cells in the cervix have a low degree of deformation (nuclear-to-cytoplasmic ratio increase and degree of nuclear abnormality, etc.), and some of them exist in the form of single small cells instead of agglomerated cells. Therefore, in the current intelligent auxiliary screening of cervical cancer It is difficult to detect abnormal cervical cells during the inspection process, resulting in low detection accuracy of abnormal cervical cells
