title = "Gel phantom containing controlled air to test Triggered HIFU exposure sequence",
abstract = "An optically transparent phantom containing a controlled content of air was developed for dosimetry studies of Triggered HIFU (High Intensity Focused Ultrasound) exposure, in which a high intensity short pulse (Triggering Pulse) is used in order to trigger cavitation and enhance the heating effect of an immediately subsequent continuous wave (CW) exposure CW (Heating Waves) with intensity and duration typical of conventional HIFU treatment. The air content was controlled by the time and pressure of degassing during gel formation. We measured the temperature change in the gel with a film thermocouple at the HIFU focus. The temperature rise induced by a 100 μs Triggering Pulse at 10 kW/cm2 of followed by a 10 s CW exposure at 0.2 kW/cm2 was higher than the Heating Waves alone, by up to six to ten times.",
