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.

Three of our pioneering journal publications in this area include:

  • Wiacek A, Rindal OMH, Falomo E, Myers K, Fabrega-Foster K, Harvey S, Bell MAL, Robust Short-Lag Spatial Coherence Imaging of Breast Ultrasound Data: Initial Clinical Results, IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 66(3):527-540, 2019 [pdf]

Prof. Bell Wins ORAU Ralph E. Powe Junior Faculty Enhancement Award

Congratulations to Prof. Bell, who was selected to receive a competitive ORAU Ralph E. Powe Junior Faculty Enhancement Award, which is designed to help ORAU member institutions retain their best young faculty members. This award will provide seed funding for the project entitled, Robust Short-Lag Spatial Coherence Imaging of Hypoechoic Breast Masses, which focuses on development and patient testing of a novel beamforming method developed in the PULSE Lab to differentiate fluid-filled masses from solid breast masses with greater certainty than the current ultrasound beamforming methods used in breast clinics today. Fluid-filled masses are often benign, but with current uncertainty rates, many fluid-filled masses undergo the same costly, time-consuming, and anxiety-provoking diagnostic work-ups as malignant masses, which are often solid.

The long-term goal of this research is to improve breast cancer screening and detection for the benefit of patients and for the redistribution of more healthcare system resources to cancer patients who need them most.

Prof. Bell Receives NIH Trailblazer Award

Prof. Bell received the NIH Trailblazer Award from the National Institute of Biomedical Imaging and Bioengineering to support our project entitled, A Machine Learning Alternative to Beamforming to Improve Ultrasound Image Quality for Interventional Access to the Kidney. This project is motivated by the clinical challenges surrounding artifacts in ultrasound images, specifically artifacts caused by multipath scattering and acoustic reverberations (which occur when imaging through the abdominal tissue of overweight and obese patients or visualizing metallic surgical tools). There are no existing solutions to eliminate these artifacts based on today’s signal processing techniques. The goal of this project is to step away from conventional signal processing models and instead learn from raw ultrasound channel data examples with state-of-the-art deep learning techniques that differentiate artifacts from true signals to deliver a new class of clearer, easier-to-interpret ultrasound images that we call CNN-Based images. This work will be completed in collaboration with Austin Reiter, PhD and Kelvin Hong, MD.

Two of our pioneering publications in this area include:

  • D Allman, A Reiter, MAL Bell, Photoacoustic source detection and reflection artifact removal enabled by deep learning, IEEE Transactions on Medical Imaging, 37(6):1464-1477, 2018 [pdf | datasets code]
