Description
In vitro heating effect produced by a focused ultrasound transducer has been investigated by using visual methods. Three experiments were performed on TMM (Tissue Mimicking Material), sheep liver and sheep lung. HIFU (High Intensity Focused Ultrasound) transducer with a resonance frequency of 1.1 MHz and 3.3 MHz was used as source. Ultrasound power, distance, frequency and harmonics of heating effect was studied. Effect of ultrasound in liver and lung's pieces were displayed and dimension of cauterization has been measured. Previous temperature measurement results for TMM were compared with liver and lung measurement results so that it is possible to transfer the laboratory measurements to the clinical studies. All measurements were carried out in the system at TUBITAK UME (The Scientific and Technological Research Council of Turkey, the National Metrology Institute) Ultrasound laboratory.
