Abstract
A magnetic resonance image generating apparatus comprising a first radiation source capable of emitting a first radiation of a frequency selected to excite nuclear spin transitions in selected nuclei in a sample being imaged and means for detecting free induction decay signals from said selected nuclei, characterized in that said apparatus further comprises a second radiation source capable of emitting a second radiation of a frequency selected to excite electron spin transitions coupled to the nuclear spin transitions of at least some of said selected nuclei.
Claims8
A magnetic resonance image genrating apparatus comprising a first radiation source means for emitting pulse sequences of a first radiation of a frequency selected to excite nuclear spin transitions in selected nuclei in a sample being imaged, a second radiation source means for emitting a second radiation of a frequency selectd to excite elecron spin transitions coupled to the nuclear spin transitions of at least some of said selected nuclei, a primary magnet means for generating a substantially uniform nagnetic field, magnetic field gradient generating means for imposing a gradient on the magnetic field experienced by said sample during gradient imposition periods within said sequences, means for detecting free induction decay signals from said selected nuclei during detection periods within said sequences, and means for transforming said detected free induction decay signals into a magnetic resonance image of at least part of said sample, said second source means for emitting said second radiation during the delay period a final detection period of one of said sequences and an initial pulse of said first radiation in a subsequent sequence.
