Out‐of‐field neutron radiation from clinical proton, helium, carbon, and oxygen ion beams

Medical Physics, EarlyView.
Abstract Background In hadron therapy, out‐of‐field doses, which may in the long‐term cause secondary cancers, are mostly due to neutrons. Very recently, 4He and 16O beams have been added to protons and 12C ions for clinical therapy. Purpose The focus of this article is to compare secondary neutron doses produced by clinical protons, 4He, 12C, and 16O ...

A neuromorphic system based on spiking‐timing‐dependent plasticity for evaluating wakefulness and anesthesia states using intracranial EEG signals

VIEW, EarlyView.
Existing clinical approaches for assessing anesthesia depth often rely on physiological and behavioral indicators, which can be unreliable due to uncertain correlation with patient consciousness. This study presents a neuromorphic SNN with STDP, implemented on an field‐programmable gate array (FPGA) platform, enabling real‐time iEEG‐based assessment of
