High magnetic field strength (3 Tesla or 7 Tesla) MRI has become popular in
the last few decades due to the better signal to noise ratio and/or
resolution it provides which leads to image quality improvement and
diagnostic advantages. Two challenges associated with high field MRI are
increased image shading and increased tissue heating which degrade the
image quality and limit imaging speed. Parallel transmission technology has
the potential to address both the image shading and tissue heating
challenges, however it is associated with implementation and safety
challenges. In this talk, the application of parallel transmission to brain
imaging at 7 Tesla and fetal imaging at 3 Tesla MRI will be discussed. A
thorough framework for safe and effective implementation of parallel
transmission is proposed and demonstrated through simulation studies as
well as phantom experiments.
