Patent ID: 8170643

Claim:
A system for irradiating a target with electromagnetic radiation to produce a heated region, comprising: a coupling device operable to couple electromagnetic radiation from a transmitting body coil located in an inner area of a magnetic resonance imaging (MRI) system, said MRI system including an MRI electromagnetic radiation source coupled to the transmitting body coil to supply radio frequency electromagnetic radiation to the body coil as part of the MRI imaging process; a plurality of energy radiator applicators having an energy supply connection point electrically connected to the coupling device to receive electromagnetic radiation energy coupled from the transmitting body coil and supplied to the transmitting body coil by the MRI electromagnetic radiation source, with each of the energy radiator applicators operable to emit a radio frequency heating signal; and a bolus filled with a dielectric fluid and having an open center region configured to receive a body, wherein the bolus is positioned within the inner area of the MRI system and is operable to receive the radio frequency heating signals from the plurality of energy radiator applicators and direct the radio frequency heating signals into a section of the body to produce a heated region within the body.
