基于数据融合的智能医疗辅助诊断方法

Intelligent medical assistant diagnosis method based on data fusion

医生诊断需要结合临床症状、影像检查等各种数据,基于此,提出了一种可以进行数据融合的医疗辅助诊断方法.将患者的影像信息(如CT图像)和数值数据(如临床诊断信息)相结合,利用结合的信息自动预测患者的病情,进而提出了基于深度学习的医疗辅助诊断模型.模型以卷积神经网络为基础进行搭建,图像和数值数据作为输入,输出病人的患病情况.该医疗辅助诊断方法能够利用更加全面的信息,有助于提高自动诊断准确率、降低诊断误差;另外,仅使用提出的医疗辅助诊断模型就可以一次性处理多种类型的数据,能够在一定程度上节省诊断时间.在两个数据集上验证了所提出方法的有效性,实验结果表明,该方法是有效的,它可以提高辅助诊断的准确性.

In the field of medicine,in order to diagnose a patient’s condition more efficiently and conveniently,image classification has been widely leveraged.It is well established that when doctors diagnose a patient’s condition,they not only observe the patient’s image information(such as CT image)but also make final decisions incorporating the patient’s clinical diagnostic information.However,current medical image classification only puts the image into a convolution neural network to obtain the diagnostic result and does not use the clinical diagnosis information.In intelligent auxiliary diagnosis,it is necessary to combine clinical symptoms with other imaging data for comprehensive diagnosis.This paper presented a new method of assistant diagnosis for the medical field.This method combined information from patients’imaging with numerical data(such as clinical diagnosis information)and used the combined information to automatically predict the patient’s condition.Based on this method,a medical assistant diagnosis model based on deep learning was proposed.The model takes images and numerical data as input and outputs the patient’s condition.Thus,this method is comprehensive and helps improve the accuracy of automatic diagnosis and reduce diagnostic error.Moreover,the proposed model can simultaneously process multiple types of data,thus saving diagnosis time.The effectiveness of the proposed method was verified in two groups of experiments designed in this paper.The first group of experiments shows that if the unrelated data are fused for classification,the proposed method cannot enhance the classification ability of the model,although it is able to predict multiple diseases at one time.The second group of experiments show that the proposed method could significantly improve classification results if the interrelated data are fused.
