论文摘要

本文中,我们介绍了一种基于混合学习的系统,旨在支持医学领域的医生有效诊断良性阵发性阵发性位置眩晕(BPPV)疾病,旨在支持医学领域的医生。鉴于患者在DIX-HALLPIKE和侧向转弯测试中的身体姿势,两只眼睛的视觉信息都被捕获并喂入LAD中,以分析和分类为患者可能患有六种可能的疾病之一。提出的系统由两个流组成:(1)基于RNN的流,该流对两只眼睛的原始RGB图像提取视觉特征和每只眼睛的光流,然后进行三元分类,以确定左/右后管(PC)或其他; (2)当学生分类为非PC时检测到瞳孔的瞳孔检测器流并将击败的方向和强度分类为将非PC类型分类为其余四个类别:地球体BPPV(Geotropic BPPV)(左右)和apogeotropic BPPV(左右)。实验结果表明,借助患者的身体姿势,该系统可以准确地将BPPV疾病分类为六种类型的疾病,验证集的精度为91%。所提出的方法可以成功地以93%的后管道疾病对疾病进行分类,而地球疾病和地球性疾病的疾病则可以成功地分类93%,为使用医疗数据铺平了潜在的研究方向。

Herein, we introduce "Look and Diagnose" (LAD), a hybrid deep learning-based system that aims to support doctors in the medical field in diagnosing effectively the Benign Paroxysmal Positional Vertigo (BPPV) disorder. Given the body postures of the patient in the Dix-Hallpike and lateral head turns test, the visual information of both eyes is captured and fed into LAD for analyzing and classifying into one of six possible disorders the patient might be suffering from. The proposed system consists of two streams: (1) an RNN-based stream that takes raw RGB images of both eyes to extract visual features and optical flow of each eye followed by ternary classification to determine left/right posterior canal (PC) or other; and (2) pupil detector stream that detects the pupil when it is classified as Non-PC and classifies the direction and strength of the beating to categorize the Non-PC types into the remaining four classes: Geotropic BPPV (left and right) and Apogeotropic BPPV (left and right). Experimental results show that with the patient's body postures, the system can accurately classify given BPPV disorder into the six types of disorders with an accuracy of 91% on the validation set. The proposed method can successfully classify disorders with an accuracy of 93% for the Posterior Canal disorder and 95% for the Geotropic and Apogeotropic disorder, paving a potential direction for research with the medical data.
