Getting What You Want: Managing the Mayhem
Xiaoping Wu1
1CMRR - University of Minnesota, United States
Synopsis
In this educational lecture, we will review possible strategies that can be used to manage the mayhem of RF non-uniformity and SAR, the two major challenges at ultrahigh field. Specifically, we will start with a brief discussion as to what is possible on a standard system and will then focus on what is possible when parallel transmission is available. In particular, we will discuss the various forms of parallel transmission alongside their demonstrated utility for brain and body imaging at 7 Tesla and above. We will also explain how parallel transmission can be used to reduce or manage SAR. In the end, we will summarize what is learned and will discuss other aspects of parallel transmission that are not covered in this lecture.
