Abstract
AIM: Diagnostic ultrasound is a powerful, versatile and safe investigation tool in modern medicine. Methods are described, and conclusions are drawn and recommendations given for a responsible use of diagnostic ultrasound. METHOD AND RESULTS: Because of the increasing ultrasonic power penetrating the body, diagnostic techniques cannot always be applied without risk. The increase in temperature induced by ultrasound absorption should be considered a potential hazard in certain applications. The paper presents the physical basis for a quantitative estimation of the risk of a specific treatment plan. Mathematical models and the thermal index are described. CONCLUSION: Our findings and recommendations form a viable basis for the responsible use of diagnostic ultrasound.
