Synopsis

Keywords: Low-Field MRI, RF Arrays & Systems, X-nuclei, phosphorus-31

Development of a phosphorus-31 resonant NMR coil in order to estimate the T1 and T2 relaxation times. A didactic low-field 0.57 T MR-system and a 85% phosphorus acid solution as phantom are used to generate a sectional image of the phantom. In addition the spin-lattice and spin-spin relaxation signals are recorded, averaged and fitted in order to determine the T1 and T2 relaxation times. After exponential curve fitting the following relaxation times T1=0.781 s and T2=0.342 s are calculated.
