Abstract: An exemplary coil arrangement can be provided, which can include, for example, coil element(s) having a parallel resonant circuit at a port, where the coil element(s) is detuned by causing a low impedance at the port. Pre-amplifier arrangements can provide a low impedance at the port of the coil element(s) to suppress the induced current on the coil element(s) thereby reducing the inductive coupling to neighboring element(s). The coil element(s) can include an inductance and a capacitance which cancel each other out. The inductance and the capacitance can cancel each other out such that an impedance of the coil element has no imaginary part at a working frequency. An impedance of the coil element(s) in free space includes a real part that can be greater than a sum of losses for the coil element(s).

Abstract: A plurality of stimulations is transmitted to tissue or other material using one or more transmitters. The plurality of signals associated with the excited tissue and the transmitted stimulations are measured. The measured signals are processed to generate field-related quantities, such as B1+ and/or MR signal maps. Field-related quantities are generated also from simulation, by calculating the one or more incident fields from a simulator model of the one or more transmitters and assuming a given distribution of electrical properties in the tissue or other material. Field-related quantities generated from simulation and experimental procedures are compared to each other. The assumed electrical properties distribution is updated and the procedure is repeated iteratively until the difference between simulated and experimental field-related quantities is smaller than a threshold.

Abstract: A method and system for providing an article of manufacture with increased longevity of hyperpolarized 1H signals (and other species) for NMR spectroscopy and MRI. The method involves providing a material including a molecular species susceptible of NMR spectroscopy, by providing parahydrogen (and other appropriate species) to disperse within the material/solvent to establish increased longevity of the NMR signals. The material can be in a solution with a surfactant and catalysts added to enhance the persistence of parahydrogen (or other species) in the form of enhanced solubility, microbubbles or micelles and resultant hydrogenation (or other species) of the material.
