Title:
REPETITION TIME DETERMINING METHOD
Document Type and Number:
Japanese Patent JP3844727
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize a method for determining an optimum value as minimum repetition time (TR).
SOLUTION: On pulse sequence for magnetic resonance imaging, the minimum TR based on the heating limit of a gradient coil or the like, RF pulse interval limit and pulse sequence time length limit is computed (503), and the minimum TR on pulse sequence reduced in the amplitude of a gradient magnetic field signal is recomputed (505). As long as TRi<TRi-1 is in effect, recomputation of the minimum TR is repeated while reducing the amplitude of the gradient magnetic field signal, and TRi-1 when TRi<TRi-1 is no longer in effect is made to be the optimum value.
