Title
(EN) SYSTEM AND METHOD FOR FLIP ANGLE DETERMINATION IN MAGNETIC RESONANCE IMAGING
(FR) SYSTÈME ET PROCÉDÉ DE DÉTERMINATION D'ANGLE DE BASCULE EN IMAGERIE PAR RÉSONANCE MAGNÉTIQUE
Abstract
(EN)
A system and method for calculating a flip angle schedule is provided. The technique includes selecting an initial condition, providing a function for calculating flip angles, calculating flip angles, assessing the flip angles, and repeating the calculation of the flip angles by adjusting the function until a desired flip angle schedule is obtained.
(FR)
La présente invention concerne un système et un procédé permettant de calculer un programme d'angle de bascule. La technique consiste à sélectionner un état initial, fournir une fonction de calcul d'angles de bascule, calculer des angles de bascule, évaluer les angles de bascule, et répéter le calcul des angles de bascule en ajustant la fonction jusqu'à ce qu'un programme d'angle de bascule souhaité soit obtenu.
