摘要

作者建议使用圆柱形压电换能器进行阴道或前列腺肿瘤的腔内热疗治疗，以利用5兆赫以下超声的深度穿透。不同尺寸和形状的涂抹器工作在1mhz左右已经开发。最长的是12厘米长，直径1.5厘米，使用两个4厘米长的钛酸铅锆酸盐传感器。介绍了组织等效幻象中功率分布的研究，并对结果进行了评估。

Development of new intracavitary ultrasound applicator

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.<>
