Imaging and spectroscopy of multiple nuclei with phased
arrays has demonstrable utility in magnetic resonance.
Our application involves imaging of deuterium and
proton. Deuterium has been used for glucose monitoring,
tracking bolus diffusion, and providing a signal lock.
We have developed a dual-tuned, geometrically decoupled
two-element receive array for sequential or interleaved
imaging of proton (
H) and deuterium (
at 1T. Array elements are detuned passively during
transmit with crossed diodes, while transmit elements
are detuned during receive using PIN diodes.
Images of a deuterated water phantom taken at 1T are
