Abstract
The authors suggest the use of cylindrical piezoelectric transducers for intracavity hyperthermia treatment of vaginal or prostatic tumors, to take advantage of the deep penetration of ultrasound below 5 MHz. Different sizes and shapes of applicators operating around 1 MHz have been developed. The longest is 12 cm in length and 1.5 cm in diameter and uses two lead titanate zirconate transducers of 4-cm length each. Studies of power distributions in tissue-equivalent phantoms are presented, and the results are assessed.<>
