A deep neural network-based automated detection tool could assist emergency room clinicians in diagnosing COVID-19 effectively using lung ultrasound images.

Johns Hopkins researchers have developed a deep learning-based model to detect COVID-19 infection using lung ultrasound images, according to a study published recently in Communications Medicine.

The automated detection tool uses deep neural networks (DNNs) to identify COVID-19 features in lung ultrasound B-mode images and may help clinicians diagnose emergency department patients more efficiently.

“We developed this automated detection tool to help doctors in emergency settings with high caseloads of patients who need to be diagnosed quickly and accurately, such as in the earlier stages of the pandemic,” said senior author Muyinatu Bell, PhD… Continue reading.

Traditional medical imaging – used to diagnose, monitor or treat certain medical conditions – has long struggled to get clear pictures of patients with dark skin, according to experts.

Researchers say they have found a way to improve medical imaging, a process through which physicians can observe the inside of the body, regardless of skin tone.

The new findings were published in the October edition of the journal Photoacoustics. The team tested the forearms of 18 volunteers, with skin tones ranging from light to dark. They found that a distortion of the photoacoustic signal that makes the imaging more difficult to read, called clutter, increased with darkness of skin… Continue reading.

WASHINGTON, D.C. — The American Institute for Medical and Biological Engineering (AIMBE) has announced the election of Muyinatu A. Lediju Bell, Ph.D., John C. Malone Assistant Professor, Dept. of Electrical and Computer Engineering, Johns Hopkins University to its College of Fellows. Dr. Bell was nominated, reviewed, and elected by peers and members of the AIMBE College of Fellows for pioneering contributions to development of ultrasonic and photoacoustic medical imaging systems, including coherence-based beamforming, photoacoustic-guided surgery, and deep-learning applications.

The College of Fellows is comprised of the top two percent of medical and biological engineers in the country. The most accomplished and distinguished engineering and medical school chairs, research directors, professors, innovators, and successful entrepreneurs comprise the College of Fellows. AIMBE Fellows are regularly recognized for their contributions in teaching, research, and innovation. AIMBE Fellows have been awarded the Nobel Prize, the Presidential Medal of Science and the Presidential Medal of Technology and Innovation, and many also are members of the National Academy of Engineering, National Academy of Medicine, and the National Academy of Sciences… Continue reading.
