Achievement

Roger Shih from the department of Biomedical Engineering conducted his research in microbubble ultrasound resonance. Microbubbles are injected as contrast agents for ultrasound medical imaging, and this can be be a targeted drug delivery in the future. Since actuation of microbubbles is most efficient at their resonance frequency, Roger has attempted to characterize the resonance frequency of microbubbles using ultrasound transducers, with the goal of measuring them while they are inside a microfluidic device. Using Lab View to control a function generator and oscilloscope, he has automated the process of sending signal bursts over a chosen range of frequencies, and recording each burst’s response window for later analysis. Using Matlab, he learned to generate power spectra from data and inspect the frequency domain and time domain of potential bubble bounceback signals. This achievement was made possible through the interdisciplinary collaboration effort of our IGERT.
