Abstract
A nuclear magnetic resonance imaging technique is applied to objects undergoing translational motion for analysis of objects on a conveyor passing through an imaging unit. The objects are passed through the imaging module at a predetermined velocity (v), in which there is provided: a spatially uniform, constant magnetic field (B.sub.0) substantially parallel to the direction of the velocity (v); a linear magnetic field gradient (G.sub.z) substantially parallel to the direction of the velocity (v); and a radiofrequency field (B.sub.z) pulse transverse to field B.sub.0. Selected nuclear magnetic resonance parameters from said objects are then detected for subsequent imaging and analysis.
