Abstract: A method of operating a magnetic resonance scanner includes determining a radio frequency (RF) pulse to be transmitted to jointly homogenize a flip angle and a semisolid saturation that would result from magnetization of a sample to be scanned by the MR scanner using the determined RF pulse. The method also includes controlling an RF transmit coil of the MR scanner to transmit the determined pulse. Homogenizing both semisolid saturation and excitation properties of the RF pulse allows for improved magnetic transfer ratio imaging.
