基于深度学习的肺炎医学影像自动识别与检测技术研究

基于深度学习的肺炎医学影像自动识别与检测技术研究摘要

肺炎是引起全球儿童死亡的主要疾病之一。目前，通过影像学技术进行肺炎监测已经成为一种常用的手段。然而，该技术需要专业医生进行分析和诊断，因此需要耗费大量的时间和资源，而且还存在人工诊断精度不高的问题。为了解决这一问题，本文提出了一种基于深度学习的肺炎医学影像自动识别与检测技术研究方法。

本文首先介绍了深度学习技术的基本原理和常用算法，包括卷积神经网络，循环神经网络和长短时记忆网络等。在此基础上，本文利用RSNA肺炎数据集进行了实验研究，设计了一个搭载卷积神经网络的图像识别模型。突破传统肺炎图像识别技术，实现了对图像的自动识别与分类，最终将结果反馈给医生进行判断，从而实现肺炎自动化检测。

实验结果表明，本文提出的肺炎医学影像自动识别与检测技术研究方法具有较高的准确率和鲁棒性，能够有效地识别和检测肺炎图像，并且能够帮助医生更快、更准确地进行诊断和治疗。
