Mitigating banding artifacts in <scp>balanced steady‐state free precession</scp> using parallel transmission in a single acquisition

With a tailored pair of pTx pulses, it was possible to concurrently mitigate <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>$$ {\mathrm{B}}_1^{+} $$</mml:annotation></mml:semantics> </mml:math> and ΔB₀ non-uniformities in a thin slab through the brain in a single acquisition. Although further work is needed to extend the coverage and robustness of this method before being adopted more widely, it highlights the potential of utilizing pTx capabilities beyond <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>$$ {\mathrm{B}}_1^{+} $$</mml:annotation></mml:semantics> </mml:math> correction.
