Photographs of four patients in Mini-Annular Phased Array (MAPA) applicator with 4 twin dipole antennas driven at 140 MHz.
a) Waterbolus fills extra volume inside the 24 cm diameter applicator, coupling dipole antennas to tissue.
b) Brown tape holds a single invasive #15g catheter in place which extends diagonally across the tumor volume and is filled with 4 stationary Luxtron 3100 fiberoptic sensors spaced 1.5 cm apart along the catheter.
c) Patient leg in applicator inside MR magnet during hyperthermia treatment.
d) MAPA on lower arm sarcoma prior to positioning patient in MR magnet.
