Abstract Sonodynamic therapy is a minimally invasive high-intensity focused ultrasound (HIFU) based that combines sonosensitizer and reactive oxygen species (ROS), which are produced by acoustic cavitation. In this paper, we experimentally examined the effectiveness of proposed method scanning focus in direction HIFU propagation for continuously generating cavitation clouds to expand region ROS...

Combined sonication with dual-frequency ultrasound has been investigated to enhance heat transfer in forced convection. The test section used for this study consists of a channel with, on one hand, heating blocks normal the water flow, equipped thermocouples, and, other two ultrasonic emitters. One is facing blocks, thus field perpendicular, and second collinear flow. Two types waves were used:...

Introduction When a liquid is irradiated with high-intensity and low-frequency ultrasound, acoustic cavitation occurs and there are some methods to determine and quantify this phenomenon. The existing methods for performing these experiments include sonochemiluminescence (SCL) and chemical dosimetric methods. The particles in a liquid decrease the ultrasonic intensity threshold needed for cavit...
