Deep learning synthetic computed tomography supported head-and-neck adaptive radiotherapy dose recalculation
Synthetic computed tomography from cone-beam computed tomography achieved a 98.7% gamma pass rate for head-and-neck dose recalculation.
Physics-constrained network improved cone-beam computed tomography reconstruction from orthogonal pelvic radiographs
A physics-constrained network reconstructed pelvic cone-beam computed tomography from two simulated radiographs with substantially lower error than generative baselines.
Dual-scan conformal cone-beam computed tomography improves target-region image quality
Dynamic collimation improved target-region contrast and signal-to-noise ratio while preserving full-field information without increasing the total photon budget.
