Nuclear magnetic resonance apparatus

Abstract

Abstract PURPOSE:To eliminate manual adjustment having an individual difference, in outputting frequency spectrum by treating an inputted digitalized signal to be detected, by automatically compensating phase difference of a reference wave and a nuclear magnetic resonance signal. CONSTITUTION:Two phase detectors 6A, 6B respectively separate a nuclear magnetic resonance into two analogue signals Fc'(t), Fs'(t) by phase detection due to a reference wave. Separated two signals Fc'(t), Fs'(t) are amplified by amplifiers 8A, 8B and, after a high frequency component is removed by a low pass filter 9A, 9B, two signals Fc'(t), Fs'(t) digitalized by A/D converter 10A, 10B are inputted to a phase compensation treating device 11 This phase compensaton treating device 11 is a digital operation apparatus which calculates the phase difference of the reference wave and the nuclear magnetic resonance signal and outputs frequency spectrum removed from the influence due to the phase difference and constituted so as to perform operation according to predetermined order and to output projection data p(i) to an image treating apparatus 12.
