Deep Learning for Pneumonia Diagnosis: A Custom CNN Approach with Superior Performance on Chest Radiographs

Authors

Abstract

A major global health and wellness issue causing major health problems and death, pneumonia underlines the need of quickly and precisely identifying and treating it. Though imaging technology has advanced, radiologists manual reading of chest X-rays still constitutes the basic method for pneumonia detection, which causes delays in both treatment and medical diagnosis. This study proposes a pneumonia detection method to automate the process using deep learning techniques. The concept employs a bespoke convolutional neural network (CNN) trained on different pneumonia-positive and pneumonia-negative cases from several healthcare providers. Various pre-processing steps were done on the chest radiographs to increase integrity and efficiency before teaching the design. Based on the comparison study with VGG19, ResNet50, InceptionV3, DenseNet201, and MobileNetV3, our bespoke CNN model was discovered to be the most efficient in balancing accuracy, recall, and parameter complexity. It shows 96.5% accuracy and 96.6% F1 score. This study contributes to the expansion of an automated, paired with a reliable, pneumonia finding system, which could improve personal outcomes and increase healthcare efficiency.
