Research Interests
Biomedical ultrasound, diagnostic imaging, medical image quality, ultrasound system design, signal and image processing鈥�
Assistant Professor Nick Bottenus'听research is focused on developing system-level solutions to problems in diagnostic ultrasound imaging. Ultrasound imaging is used in wide-ranging clinical settings from screening to intervention and follow-up, but the image quality often falls short of doctors' needs for numerous reasons. The human body is a complex acoustic environment that distorts the sound from the ultrasound transducer, producing operator- and patient-dependent image artifacts that can confound diagnosis. His lab develops complementary transducer sampling, acoustic signal processing, and image interpretation methods to more robustly provide doctors with useful information across varied patient populations and applications.
Societal Impact
Modern healthcare depends on high-quality, reliable and accessible medical imaging technologies to inform clinical decision making, both by expert clinicians and computer algorithms.
