| Abstract: | We constructed and studied an ultra low-field nuclear magnetic resonance imaging system using a HTS rf SQUID and room-temperature coils. We recorded the free induction decay signals of 1H by employing a measuring field, B m, of 44.8???T and a polarizing field, B p, of 36.8?mT; in the presence of ? B Z /? z and ? B Z /? y gradients of the order of 0.8???T/m, we were able to obtain a quasi two-dimensional 4-pixels image of a simple water phantom. |
