Abstract

A hyperthermia applicator/MRI probe assembly for hyperthermia treatment of a subject. The assembly includes a hyperthermia applicator for heating target regions of a subject and a MRI probe which is utilized to monitor temperatures within the heating region. The hyperthermia applicator and MRI probe are coupled to a control system which receives information from the MRI probe and utilizes the information to control the hyperthermia applicator so as to maintain constant, desired temperatures within the heating region. The hyperthermia applicator/MRI probe assembly of the present invention allows for temperature control within about 0.5.degree. C.
