Abstract (in Japanese) (See Japanese page) 
(in English) Chronic obstructive pulmonary disease (COPD) requires spirometry for diagnosis, but the test imposes a significant burden and is influenced by patient condition and examiner skill. This study investigates an alternative approach using chest X-ray fluoroscopy and deep learning to estimate spirometry values. We analyzed 88 cases with transfer learning models (GoogLeNet, ResNet, VGG) and BiLSTM for video processing, comparing original and processed images. Results showed higher correlations for VC, ERV, and FVC, particularly with processed images, while FEV1.0 remained low due to breathing pattern differences. Combining image processing and deep learning may enable less invasive respiratory function assessment.
