Abstract: Monte Carlo simulation of optical photon transport is critical for modeling scintillation detectors but is computationally expensive. We propose OptiFlow, a flow-matching based generative ...

Measuring blood flow in the brain is critical for understanding response to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. Obtaining such ...
