APPARATUS FOR PRODUCING IMAGES OF AN OBJECT UNDER EXAMINATION WITH NUCLEAR MAGNETIC RESONANCE

1. Nuclear magnetic resonance apparatus for producing images of an object (12) to be investigated, where magnetic coils (4, 5, 7) are provided to apply fundamental fieds and gradient fields to the object (2) to be investigated, and which serve to detect deflection of the atomic cores of the object (...

Zusammenfassung:1. Nuclear magnetic resonance apparatus for producing images of an object (12) to be investigated, where magnetic coils (4, 5, 7) are provided to apply fundamental fieds and gradient fields to the object (2) to be investigated, and which serve to detect deflection of the atomic cores of the object (2) to be investigated out of their equilibrium position using a magnetic, high-frequency excitation pulse, and comprising an image reconstruction device (13) which reproduces an image in a predetermined field, characterized in that the homogeneity range of the fundamental field magnet (4) within the measurement field (A, B) is smaller than the measurement field, and that the gradient field extends monotonically over the entire measurement field.
