Abstract
A whole volume shoulder coil for MRI includes two opposed coils one attached by a knuckle held captive in a sliding track to provide bounded translation rotation and angling of that coil with respect to the opposed coil. The coil position may be fixed by means of a single adjustment which clamps the knuckle against the track. The coils includes fusible links separated from the coil by a current divider which also serves to detune the coil when the fuse is opened. Varactor diodes are used to tune the coil. The DC control voltage for the diodes is combined with the signal from the coil and later separated by tuned filters to reduce cabling.
