Résumé :
Chest radiography is the most widely used imaging modality for screening and follow-up. Dynamic chest radiography (DCR) extends conventional radiography by enabling functional assessment using flat-panel detector (FPD)-based systems. Quantitative and time-series analysis of DCR allows evaluation of respiratory and circulatory dynamics through lung density changes, diaphragm motion, and tracheal diameter. However, these approaches remain limited by the two-dimensional projection nature of X-ray imaging, motivating the integration of artificial intelligence and in silico–based strategies to enable higher-dimensional understanding of spatiotemporal patterns.
We present a unified framework integrating DCR, artificial intelligence, and in silico–based training strategies. We first enhance two-dimensional projections via image decomposition, then estimate lung volume and respiratory function, and finally reconstruct four-dimensional (4D) representations from dynamic X-ray time-series data using deep learning. Developed using large-scale virtual datasets and validated on clinical cases, these approaches may enable functional and quantitative chest radiography, bridging the gap between low-cost X-ray imaging and advanced modalities such as CT.
