Abstract: A handheld battery powered apparatus for examining a body of living tissues, which tissues may contain a neoplasm, utilizing a light source for illuminating the tissues comprising a D shaped array of high intensity light emitting diodes overlaid by an optically transparent window, means for reproducing the intensity of the light, means for applying ultrasound to the neoplasm positioned in the centre of the array, means for receiving reflected ultrasound from blood vessels in the tissues also situated in the D shaped array, and a loudspeaker or other means for reproducing the blood flow signals.

Abstract: 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.Temperature sensing means (10) may be operatively 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.A liquid bath (5) may be provided for being located between the array (1) and the skin (14) 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 causing collateral damage.
