Abstract

This unit discusses nulling of remaining signal from a RF pulse prior to the next RF pulse. This is to avoid mixing leftover signal with the signal generated from the next RF pulse. The slice select profile is also discussed in detail. The power of the RF pulse and its limit imposed by the Food and Drug Administration (FDA) is also discussed.
