Schematic of X-ray imaging setup and framework. (a) A schematic of the experimental setup. (b) Expiratory imaging strategy during mechanical ventilation. The camera, shutter, and motorized stages are synchronized. The images are only captured at the expiration phase by TTL triggering signal fired from the mechanical ventilator during rotation of the motorized stage. (c) The neural network optimization steps to reconstruct computed tomography images using extended deep image prior.
