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 ) substantially parallel to the direction of the velocity (v); a linear magnetic field gradient (G ) substantially parallel to the direction of the velocity (v); and a radiofrequency field (B ) pulse transverse to field B . Selected nuclear magnetic resonance parameters from said objects are then detected for subsequent imaging and analysis.

On-line NMR imaging of a solid or liquid object undergoing continuous translational motion

A nuclear magnetic resonance spectroscopic technique is applied to objects undergoing translational motion for chemical analysis of objects on a conveyor passing through a detector module. The objects are passed through the detector module at a predetermined velocity V, in which there is provided a spatially uniform, constant magnetic field B , substantially parallel to the direction of the velocity v and a radio frequency field B pulse transverse to the field B . Selected nuclear magnetic resonance parameters from the objects passing through the detector module are then used to determine chemical composition or changes therein.
