Prof. Bell Receives NIH R01 Grant

Prof. Bell received a $1.4M NIH R01 grant from the National Institute of Biomedical Imaging and Bioengineering to support our project entitled, Minimizing Uncertainty in Breast Ultrasound Imaging with Real-Time Coherence-Based Beamforming. This project is motivated by the clinical challenges surrounding ultrasound images yielding inconclusive results in a subset of patients, necessitating biopsies, aspirations, or follow-up imaging, which increase patient anxiety and places additional burdens on the time available for clinical care and the resource allocations of our healthcare system. The goal of this project is to develop new, real-time ultrasound imaging technology that will simplify clinical workflows by distinguishing fluid-filled masses from solid masses and from complex cystic and solid masses, which all appear hypoechoic in traditional ultrasound B-mode images. This work will be completed in collaboration with breast radiologists Eniola Oluyemi, MD, Kelly Myers, MD, Emily Ambinder, MD, and Lisa Mullen, MD.
