Optimization of flip angle for T1 dependent contrast in MRI.
The flip angle which maximizes contrast between materials with different T1 can be calculated from the root of a cubic expression. A simple closed form expression can be used if contrast is defined in a differential sense and results in only slight contrast loss even with large T1 differences.
