This Ernst angle calculator determines the optimal flip angle which maximizes the MR signal for a given T1 and TR.

Hint: You may want to use the Parameter Database to find the T1 value you are looking for.

Hint: You can input multiple T1s. They may be separated by any combination of the following delimiters: comma, space, semicolon, newline. Plots will only be displayed for the first 5 T1s.
