NMR machine phantom and a method of measuring the characteristics of a magnetic field using such a phantom

摘要

The formation of a NMR machine phantom having a homogeneous material serving for forming the image which is confined to precise positions. The precise positions are evenly distributed in the form of a matrix so that a particular image formation method may be used. The combination of the image formation method and the matrix distribution allows for obtaining information with respect to the field at numerous points and increases the speed at which these points are determined.
