Pulmonary diseases, including asthma, chronic bronchitis, and pulmonary fibrosis, are becoming increasingly prevalent worldwide. These conditions are often aggravated by environmental pollution and unhealthy lifestyle factors, making early and accurate diagnosis essential for effective treatment and improved patient outcomes. Recent advances in Artificial Intelligence (AI) have opened new possibilities for enhancing medical diagnostic processes. In this context, this project focuses on multi-class classification of pulmonary fibrosis using CT scan images and Transformer-based deep learning models ().
