Abstract

PURPOSE:To simply correct a phase error by utilizing useful phase data, by calculating the peak position of a receiving signal by interpolation using Fourier transform not only to remove the phase error but also to calculate phase offset and preserving phase data to perform calculation. CONSTITUTION:A receiving signal is taken in and subjected to Fourier transform with respect to a time to perform the zero filling of the receiving signal corresponding to zero phase encoding quantity and the data subjected to zero filling is subjected to Fourier inverse transform. Next, the peak position of the receiving signal is calculated on the basis of the obtained data and a peak position shift time is calculated on the basis of the peak position and the first phase correction quantity is calculated. Further, the phase correction quantity for correcting phase offset is calculated and the second phase correction quantity to arbitrary phase encoding quantity is multiplied to correct a phase and Fourier transform is performed in a phase encoding direction to obtain an image. By this method, phase error quantity can be simply corrected.
