Abstract

The treatment of discrete liver tumours is often a difficult clinical problem. High intensity, focused ultrasound may provide one form of therapy for such disease. The ability to focus ultrasound precisely on a predetermined volume allows the possibility of selective tissue destruction at this position without damage to intervening tissues. The authors have investigated this both in vivo and in excised liver samples in vitro. Quantitative and qualitative studies have been carried out on the relationship between the ultrasonic exposure and the lesion shape, position and volume. In addition, the highly echogenic nature of the ultrasonic lesion has been studied, in an attempt to determine whether 'real time' observation of the extent of tissue damage is feasible.
