Abstract
A sweep generator,applies a range of frequencies to an rf coil,to detect the resonant frequency of a field generated by a magnet,. A frequency to current converter,applies an auxiliary magnetic field to tune an MRI apparatus to the resonant frequency of the rf coil. A flexible coil of one turn (,) or two or more turns (,) has a plurality of segments (,). One of the belt has a contact k,, (k,′), which is electrically connectable to one or more contacts k,, (k,′), k,, (k,′), etc. located between the ends of the segments. For each connection to successive contacts, the length of the coil and its inductance increases by the added impedance DL,between contacts k,and k,. That increase of inductance is nullified by capacitors DC,located between segments.
