Document Type and Number:
Japanese Patent JP2970704
Kind Code:
B2
Abstract:
PURPOSE:To decrease the capacity of data and to improve resolution by taking out the data when all other time axes are made to be O in order to obtain the phase- corrected value of a certain axis, using the data as the one-dimensional FID data, performing the one-dimensional Fourier transformation for the data, correcting the phase at the obtained one-dimensional vector, and performing this processing for each time axis. CONSTITUTION:In a multidimensional nuclear-magnetic-resonance measuring method, data when the values on all other time axes are approximately '0' are taken out in order to obtain the phase correcting value of a certain axis. Thus, the one- dimensional FID data are obtained. The data undergo one-dimensional Fourier transformation. The phase is corrected so that an absorbing waveform is obtained at the obtained one-dimensional spectrum, and the corrected value is obtained. This processing is performed for each time axis. Since the number of the one-dimensional FID data is few, the corrected phase value can be readily obtained. The corrected phase value can be obtained before the multidimensional Fourier transformation. As a result, the data at an imaginary number part are discarded, and the absorbing spectrum is obtained. Therefore, the number of the data can be made half, and the resolution is improved.
