Abstract
A pickup coil for magnetic resonance imaging (MRI) includes a single thin metal copper sheet which is covered with cloth-like material with the interior of the two ends of the coil being covered with VELCRO-type connective material so that they adhere together. Thus, this provides a conforming fit to various specimens of varying diameters and configurations. The two ends of the coil are held by and inserted in a capacitive tuning unit which compensates for the resistive loading caused by the specimen and also for implementing the needed resonance condition.
