Claim 1
Independent Claim
102 words
THE METHOD OF MEASURING MEAN CONTAINER SIZE WHICH COMPRISES: (A) FILLING A CONTAINER WITH A LIQUID EXHIBITING A MACROSCOPIC MAGNETIC MOVEMENT. (B) SUBJECTING THE LIQUID WHILE IN SAID CONTAINER TO NUCLEAR MAGNETIC RESONANCE INCLUDING THE APPLICATION OF PULSED MAGNETIC FIELDS TO PRODUCE SPIN ECHOES UNDER GIVEN POLARIZING CONDITIONS WITH EFFECTIVE TIM INTERVALS BETWEEN SAID PULSED FIELDS AND SAID ECHOES WHICH ARE PREDETERMINED TO PRODUCE SIGNALS REPRESENTATIVE OF AN APPARENT DIFFUSION CONSTANT OF SAID LIQUID. (C) VARYING SAID FIELD CONDITIONS AND SAID INTERVALS TO CAUSE SAID SIGNALS TO VARY, AND (D) MEASURING SAID SIGNALS IS CORRELATION WITH SAID INTERVALS AND SAID FIELD CONDITIONS.
