Treatment planning for ion therapy requires precise knowledge about the biological effectiveness of particle beams, which is strongly determined by the microscopic radial energy deposition around individual ion tracks. Therefore, we applied the Local Effect Model (LEM) to investigate the dependence of the relative biological effectiveness (RBE) on different representations of the radial dose di...

BACKGROUND The feasibility, safety, and potential demand of emergent magnetic resonance imaging (MRI) of patients with a cardiac implantable electronic device (CIED) in emergency situations are unknown. METHODS We retrospectively compared emergent and scheduled MRI orders for patients with CIEDs at Kameda General Hospital, a tertiary hospital in Japan, from October 2012 to September 2016. R...
