Biomedical acoustics is a growing field comprised of individuals who study the interaction of sound with biological materials. While ultrasound in medicine is most associated with fetal imaging, researchers and clinicians continue to push the boundaries of ultrasound to improve the diagnosis and treatment of disease. As such, this conference features special sessions on imaging the microvasculature in the brain and beamforming to improve the speed and quality of the ultrasound image. But ultrasound can also be used as a therapeutic due to absorption of the acoustic wave, radiation forces, and cavitation. On the therapy side, special sessions have been organized on: phase-change contrast agents, which can improve imaging contrast or locally deliver medications to cells; sonodynamic therapy, which involves killing cancer cells with ultrasound; sonobiopsy, which uses ultrasound to enhance the release of biomarkers for noninvasive disease diagnosis; and wave propagation in complex media, which helps us to understand our acoustic field for imaging and therapy. BATC has also organized a session on training students in technical writing. Ultrasound is an important diagnostic and treatment modality that continues to advance as researchers and physicians work to improve patient outcomes.
