Abstract
Rhinosinusitis is the fifth most common diagnosis for which antibiotics are prescribed- but it is often done in vain. Currently, the only way to fully determine whether or not such treatment is actually needed is an invasive procedure. In order to spare patients from the discomfort that it would involve, this essential step is often skipped and instead, antibiotics are prescribed regardless. Using Doppler ultrasound, it is possible to induce and measure acoustic streaming inside a cavity. This can be used in order to determine the nature of the sinus infection and hence avoid unnecessary prescriptions of antibiotics. In this master's thesis, a program was created which simpli_es and, to a degree,automates this new method of diagnosis.... (More)

In this master's thesis, a program was created which simpli_es and, to a degree,automates this new method of diagnosis. Using energy levels below the safety limits, set by the FDA, trial results were successful in inducing acoustic streaming velocities of 2 cm/s inside a phantom model. The method is ready to be used clinically using a pulse repetition frequency of 3.3 kHz. (Less)
