All-Optical Ultrasound Transducer Could Transform Keyhole Surgeries

Facebook Twitter LinkedIn Email
An optical ultrasound needle has been developed that allows heart tissue to be imaged in real-time during keyhole procedures. The technology was successfully used for minimally invasive heart surgery on pigs, giving a high-resolution view of soft tissues up to 2.5 cm in front of the instrument, inside the body. The all-optical ultrasound transducer, developed by a research team from University College London (UCL) and Queen Mary University of London (QMUL), uses light guided by miniature optical fibers to generate and receive ultrasound. The optical fiber is encased within a customized...Read full article
