B1‐MRF: Large dynamic range MRF‐based absolute B1+ mapping in the human body at <scp>7T</scp>
B1-MRF provides accurate and precise <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:semantics> <mml:mrow><mml:msubsup><mml:mi>B</mml:mi> <mml:mn>1</mml:mn> <mml:mo>+</mml:mo></mml:msubsup> </mml:mrow> <mml:annotation>$$ {B}_1^{+} $$</mml:annotation></mml:semantics> </mml:math> maps over a wide range of FAs, surpassing the capabilities of existing methods in the FA range < 60°. Its enhanced sensitivity at low FAs is advantageous for various applications requiring precise <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:semantics> <mml:mrow><mml:msubsup><mml:mi>B</mml:mi> <mml:mn>1</mml:mn> <mml:mo>+</mml:mo></mml:msubsup> </mml:mrow> <mml:annotation>$$ {B}_1^{+} $$</mml:annotation></mml:semantics> </mml:math> estimates, potentially advancing the frontiers of ultra-high field (UHF) body imaging at 7T and beyond.
