ABSTRACT:
A radio frequency coil for receiving NMR signals in the imaging of a human foot includes a bird cage structure of longitudinally separated loops joined by longitudinal segments. Some of the segments include transverse portions which define an appendant volume for receiving the toes of the foot when the foot is placed in the coil with the leg generally longitudinal and the toes extending transversely. The appendant volume allows the average radius of the coil to be decreased with a corresponding increase in signal-to-noise ratio without unduly affecting the homogeneity of the coil's reception pattern.
