Title:
OVERHAUSER EFFECT MRI RESONATOR AND OVERHAUSER EFFECT MRI MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2017/203784
Kind Code:
A1
Abstract:
The present invention provides an OMRI resonator whereby nonspecific heat absorption by a sample during electromagnetic wave feeding is suppressed, and an OMRI measurement method using the same. An OMRI resonator 1A having: an NMR coil 2 inside which a sample S is disposed; and a loop gap resonator 3A having a loop gap part 4 configured from a loop part 4A in which the sample S is set and a gap part 4B interrupting the loop part 4A, at least the loop part 4A of the loop gap part 4 being provided in the NMR coil 2, and a power receiving part 5 to which electromagnetic waves are fed by a feed antenna 6, the power receiving part 5 being connected to the gap part 4B so as not to be superposed on the loop part 4A in which the sample S is set, whereby power is received so that the electromagnetic waves fed by the feed antenna 6 are not directly radiated to the sample S set in the loop part 4A, and the power receiving part 5 causing electromagnetic field resonance in the loop gap part 4.
