Tracking motion of the heart using (HARP) magnetic resonance imaging CINE harmonic phase

摘要

(57) [Abstract] The present invention relates to a method of measuring the movement of an object such as a heart using magnetic resonance imaging. Spectral peak of the first one is obtained from at least the Fourier domain for which the pulse sequence is adapted to spatially modulate a region of interest, is spatially modulated in the subject. Harmonic phase first image to compute the inverse Fourier transform of the spectral information of the first peak, which is acquired, the calculated is determined from the spectrum peak. The above process is repeated, harmonic phase a second image is created from the spectral peak of the second distortion from the harmonic phase the first and second images is determined.
