Abstract:
A method of imaging an object undergoing continuous translational motion through a magnetic field by acquiring nuclear magnetic resonance signals therefrom comprising the steps of:conveying the object to be analyzed through an imaging module at a predetermined velocity, v; generating, within the imaging module, a spatially characterised constant magnetic field B0; generating, within the imaging module, a spatially characterised, temporally constant magnetic field gradient, Gz substantially parallel to the direction of the velocity, v; generating, within the imaging module, a radiofrequency field B1 pulse traverse to field B0; detecting nuclear magnetic resonance signals weighted with at least one selected nuclear magnetic resonance parameter from said object, said generating steps and said detecting step occurring during a period in which said object is moving at said predetermined velocity; and correcting said signal for a motional phase factor acquired from the movement of said object at said predetermined velocity through said spatially characterised fields.
