Time of flight (TOF) x-ray imaging is an emerging technology that combines high temporal resolution photon counting detector and very short x-ray pulses to provide additional information about photon interactions. For example, due to longer path lengths, scat...

Patient motion estimation is essential for various X-ray imaging applications, and is typically formulated as an optimization problem. Solution using gradient-free methods often suffer from limited accuracy and high computational cost. Gradient-based approach...
