Thermal simulations in the human head for high field MRI using parallel transmission
Journal of Magnetic Resonance Imaging, 05/04/2012
Massire A et al. – Considering parallel transmission, the recommended values of local 10–g specific absorption rate (SAR) may remain a relevant metric to ensure that the local temperature inside the human head never exceeds 39°C, although it can lead to rises larger than 1°C in the eye. Monitoring temperature instead of SAR can provide increased flexibility in pulse design for parallel transmission.
