Abstract
Clinical MRI can potentially benefit greatly from the relatively recent advent of commercial high-field (7 and 9.4 Tesla) systems. However, there are several major engineering challenges associated with high fields, the main one of which is to produce a strong, homogeneous transmit B1 field, while remaining within regulatory guidelines for tissue power deposition.
