Acoustic and Thermal Analysis in Blood Vessel into Muscle for Pressure Study Related to Cavitation

The acoustic cavitation during the application of ultrasound has been witnessed with their effect in different media. For clinical applications, it has been showed as an undesired effect. The use of Finite Element Method has been related to computational solutions for solving problems of real life for clinical problems or therapeutic uses. This paper presents a simulation made with the Finite Element Method for the acoustic and thermal analysis in muscle and a blood vessel with a transducer of 20 mm of radius, for the comparison of behavior between both tissues and their possible relation with the acoustic cavitation phenomenon. The result obtained shows the map acoustic pressure distribution with a higher pressure in the blood vessel than the muscular tissue, and a temperature increase lower than 7°C from the initial temperature (37.5°C) in the blood vessel. This work was made as an approximation of our main goal of study of acoustic cavitation.
