Fourier transformation imaging method

When the center of an object of interest imaged and the center of a display screen or image area deviate from each other, a Fourier transformation imaging method includes (a) a step of representing the amount of deviation of those centers from each other by the amount of deviation in a frequency enc...

Zusammenfassung:	When the center of an object of interest imaged and the center of a display screen or image area deviate from each other, a Fourier transformation imaging method includes (a) a step of representing the amount of deviation of those centers from each other by the amount of deviation in a frequency encoding direction and the amount of deviation in a phase encoding direction, (b) a step of converting each of the amounts of deviation in the frequency and phase encoding directions into a value calculated in terms of the amount of rotation of the phase angle of a measured resonance signal, (c) a step of correcting the amount of rotation of the phase angle of the measured resonance signal on the basis of the values obtained by the conversion, and (d) a step of Fourier-transforming the corrected signal to display an image in which there is no deviation or the center of the object of interest is located at the center of the image area.
