Summary on Grant Application Form |

This study will measure temperature rises generated by current phased array medical ultrasound system in tissue mimicking materials and compare them with predicted values. A finite difference code will calculate the nonlinear pressure fields of scanners using initial conditions measured near the array heads. The calculated absorption losses from the acoustic model will be used as heat sources for a numerical model which will perform the thermal calculations. The project will include heating at a soft tissue/bone interface using tissue mimic gels, bone mimics and fetal bone samples. Results will be compared with existing theoretical approaches (e.g. NRCP heated disk and AIUM thermal index) and measurements (e.g. NPL thermal test object). Once the theoretical model is established it will be possible to explore the influence of parameters such as absorption and its frequency dependence on thermal effects. This will be of great benefit in the design, testing, calibration and safety assessment of ultrasound systems.
