RF power duty cycle restrictions of continuous arterial spin labeling coil for 7.0 tesla perfusion magnetic resonance imaging

摘要

Here, we applied the Finite-Difference Time-Domain (FDTD) method to study the duty cycle restrictions at 7.0 Tesla [6]. We first obtained the required transverse magnetic field (B) field strength by FDTD simulations and experiments at 3.0 Tesla. The samei
