FOURIER TRANSFORM IMAGING METHOD

PURPOSE:To lower picture resolution when animation display is effected at a real time by using a high speed photographing method, so as to reduce the number of Fourier transform points, and to form a picture at a high speed, in a magnetic resonance imaging device. CONSTITUTION:Each magnetic field ge...

Zusammenfassung:	PURPOSE:To lower picture resolution when animation display is effected at a real time by using a high speed photographing method, so as to reduce the number of Fourier transform points, and to form a picture at a high speed, in a magnetic resonance imaging device. CONSTITUTION:Each magnetic field generating means, comprising a superconductive magnet 1, an inclination magnetic field source 2, and a high frequency transmitter receiver 9, a signal detecting means to amplify a plurality of nuclear magnetic resonance signals generated from an object 4 to be inspected by means of a preamplifier 5, and to produce a low frequency component by mixing together a detected signal and a reference signal generated by a reference signal generator 7 by means of an output from an orthogonal detector 6, a calculator 3 to perform computation of a detected signal, converted into digital data by an A/D converter 8, and an output means for a computing result from the calculator are provided.
