A one-two punch for photoacoustic imaging

Scientists use photoacoustic microscopy to measure various biomarkers in the body, but some of these measurements can be inaccurate due to limitations of the light-focusing beam that produces out-of-focus images. Engineers in the McKelvey School of Engineering at Washington University in St. Louis have designed a new technique that combines hardware and software innovations as […]

Less energy, better quality PAM images with machine learning

Photoacoustic microscopy (PAM) allows researchers to see the smallest vessels inside a body, but it can generate some unwanted signals or noise. A team of researchers at the McKelvey School of Engineering at Washington University in St. Louis found a way to significantly reduce the noise and maintain image quality while reducing the laser energy […]

‘Unprecedented opportunity’ to understand neurovascular recovery after stroke

Each year in the U.S., nearly 800,000 people have a stroke, which leads to more than $46 billion spent annually in health care and related costs. A powerhouse team of researchers at Washington University in St. Louis is collaborating to understand how the brain remodels after stroke with the goal of finding new therapeutic targets […]

Chan Zuckerberg Initiative names two WashU groups Frontiers of Imaging grantees

The Chan Zuckerberg Initiative (CZI) on Dec. 2 announced two research groups led by Washington University in St. Louis faculty were named Frontiers of Imaging grantees. Both groups will focus on the brain — where current imaging techniques can penetrate just about the depth of a couple of human hairs — with $1 million each […]

New faculty join McKelvey School of Engineering

Ten new faculty are set to join the McKelvey School of Engineering, bringing the total number of full-time faculty to more than 140, including 98 tenured and tenure-track faculty. “With opening of Henry A. and Elvira H. Jubel Hall for Mechanical Engineering and Materials Science and with the ongoing construction of James M. McKelvey, Sr. […]
