AI Technical Summary

Technical Problem

Existing automatic image recognition technology has difficulty distinguishing between chromosome banding aberrations caused by excessive enzymatic digestion and true structural abnormalities, leading to distorted karyotype analysis results and increasing the risk of false positives in clinical diagnosis.

Method used

By acquiring chromosome karyotype images, the contours of equally spaced bands along the length direction are extracted, a sequence of band contours is constructed, and a pre-trained recurrent neural network is used to output band contrast, generate band degradation curves, and extract attenuation coefficients to determine whether it is an artificial aberration caused by excessive enzymatic digestion or a real structural abnormality.

Benefits of technology

It has achieved accurate identification of enzymatically over-digested band distortion, avoiding misjudgment, reducing the probability of false positives in clinical diagnosis, and improving the stability and intelligence level of automatic image recognition technology.

Abstract

本申请提供一种基于人工智能的染色体核型图像自动识别方法及系统,涉及图像自动识别技术领域,通过对染色体核型图像中的染色体提取其长度方向上等间距分布的多个带纹截面轮廓;构建染色体的带纹截面轮廓序列;将所述带纹截面轮廓序列输入预训练的循环神经网络,所述循环神经网络输出每个截面位置处的带纹对比度,并根据相邻截面位置处的带纹对比度生成染色体的带纹退化曲线;提取所述带纹退化曲线的带纹对比度沿染色体长轴的衰减系数,当所述衰减系数小于预设阈值时判定染色体的带型畸变为酶解过度型人工畸变,否则判定为真实结构异常。本申请可实现染色体酶解过度型带纹畸变的精准识别,从而区分人工畸变与染色体真实异常。
