Problems solved by technology

This method is low in cost and can be applied at the grassroots level, but the specificity is not high
At present, there is still a lack of a cervical cancer screening method with good sensitivity and specificity and low price in clinical practice, which can be applied to primary hospitals with underdeveloped medical resources to improve the screening rate and accuracy of cervical cancer.

Embodiment Construction

[0029] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] The invention relates to a method for screening precancerous lesions of cervical cancer, which uses spectral extraction features to establish a neural network model to classify precancerous lesions, and utilizes image fusion technology to locate transitional zones of the cervix. The spectral detection results are displayed on the transition zone image, and different levels are represented by different color levels, which provides a more intuitive display for medical workers and provides guidance for key inspections and biopsies of lesion areas.

[0031] The data used in this method are divided into five categories, whose labels are normal, CINⅠ, CINⅡ, CINⅢ and cervical erosion. The data come from hospital clinical trials, and the labels are taken from the results of histopathological examination.

[0032] figure 1 It is a schematic diagram of the overall flo...

Abstract

The invention relates to a cervical cancer precancerous lesion screening method combining spectrums and images, and belongs to the field of spectral analysis and medical image processing. The method comprises the following steps: constructing a database according to spectrum and image data collected by a spectrum and endoscope combined probe at the same time, constructing a neural network precancerous lesion classification model by using the spectrum database, displaying the spectral diagnosis results of corresponding detection points on the images of the corresponding detection points by using different colors by utilizing image registration and fusion, reconstructing a precancerous lesion distribution diagram, and outputting the diagnosis results according to the distribution diagram. The method can be independently used as a cervical cancer screening algorithm, and can also provide image guidance for further biopsy. The diagnosis result of the method is the cervical cancer precancerous lesion distribution diagram which is objective and direct and not influenced by the technology of operators.

Description

technical field [0001] The invention relates to a screening method for cervical precancerous lesions combining spectrum and images, and belongs to the fields of spectrum analysis and medical image processing. Background technique [0002] Cervical cancer is a common gynecological malignancy, which has caused serious harm to women's health. The cure rate of early cervical cancer can reach more than 90%, while the cure rate of carcinoma in situ is 100%. Early screening of cervical cancer can prevent the continued development of cervical cancer and prevent the occurrence of cervical cancer. Therefore, early diagnosis of cervical cancer is very important. Clinically, early lesions of cervical cancer are divided into CINI grade, CINII grade and CINIII grade according to the degree of cervical epithelial cell lesions, and invasive cancer is defined as CINIII grade or later. The development of early lesions to invasive cancer is slow, and timely and universal early screening is ...
