Chinese researchers developed a flexible photoacoustic imaging technique by modifying fiber optic sensors and combining laser light and ultrasound to image biological tissue, detailed in a release from The Optical Society.

Noninvasive imaging helps cardiologists map blood flow response to physical stimuli

Photoplethysmography—a noninvasive imaging technique that allows clinicians to measure a patient’s pulse wave velocity as blood moves away from their heart—has for the first time linked alterations in the carotid system to changes in physical movement, according to research out of ITMO University in Saint Petersburg, Russia.
