Abstract
An optimal pulse power measurement method for multinuclear simultaneous integrated magnetic resonance imaging includes the following steps: successively or simultaneously exciting multiple nuclides within a slice in a same repetition time (TR) of magnetic resonance imaging (MRI); applying, in a slice encoding gradient channel, a frequency encoding gradient in a direction opposite to a slice selection gradient, and acquiring free induction decay (FID) signals of all the nuclides; simultaneously changing shaped radiofrequency (RF) pulse power values of all the nuclides for multiple times, and acquiring multiple corresponding FID signals for each nuclide; and performing Fourier transform on the FID signals of each nuclide, selecting a spectral peak in an absolute spectrum, integrating the spectral peak for comparison, and taking a shaped RF pulse power value corresponding to a maximum signal intensity of each nuclide as an optimal shaped RF pulse power corresponding to a current TR.
