ABSTRACT:
In a method of imaging a body in which nuclear magnetic resonance is excited in a region including part of the body, and the free induction decay signal is measured, a quantity of a material of known nuclear magnetic resonance properties is included in the region so as to enhance the measured free induction decay signal. This then reduces the generation of noise during subsequent processing of the signal. The material is suitably water in a container.
