ABSTRACT:
An apparatus for the examination of an object, such as a human body, by means of ultrasound and NMR methods in such a manner that both examination methods are adapted to be effected substantially simultaneously and on the same target area. The apparatus is provided with a device for radiating the magnetization of an electron spin system in the said target area in order to achieve a dynamic nuclear polarization and to amplify an NMR signal through a so-called Overhauser-phenomenon.
