Abstract
A receive loop for use in magnetic resonance imaging, comprising: a collapsible imaging coil adapted to be inserted into a patient's body and expanded therein for receiving radio frequency signals emitted by the body, the coil being characterized by an inductive impedance; a quarter-wavelength transmission line connected to the coil, the imaging coil and transmission line in combination being characterized by a capacitive impedance; and apparatus connected to the transmission line remote from the imaging coil for tuning the combination coil and transmission line to resonate in response to the body emitting the radio frequency signals, whereby the radio frequency signals are received.
