Bloch simulation results: bSSFP signal vs field strength. (A) Fixed TE = 1.5ms and TR = 3ms for all field strengths results in signal intensity that is nearly proportional to B0 with some compensation from T1 shortening at lower field. (B) Significant increase in simulated signal intensity is achieved when TR and sampling duty cycle varies proportionally to B0 such that bSSFP banding is kept constant. T1 and T2 determined were based on Bottomley et al (15). (C) Simulated signal intensity comparison using the Cartesian acquisition and proposed spiral in-out acquisition with measured T1 and T2. Signal intensity is scaled relative to blood at 1.5T for display, and relative signal intensity is provided for each tissue type.
