<p>An ultrasound hyperthermia unit for the treatment of a target tissue, includes an ultrasound transducer array (1) angled to direct sonic energy toward a target (8), wherein the array (1) comprises a plurality of divergent transducers (2) arranged radially of a central axis to provide a coherent treatment field about a central axis.</p><p>Temperature sensing means (10) maybe operative associated with the array and adapted to provide an output signal indicative of temperature values adjacent a target tumour, said signal being utilized to control the output of the transducers.</p><p>A liquid bath (5) may be provided for location between the array (1) and the skin (4) of a patient, said liquid bath being adapted to warm or induce local hyperthermia in the skin surface. The divergent array, when associated with a water bath allows a particularly effective treatment of physiotherapeutic conditions or neoplastic tissues without previously experienced colateral damage.</p> |
