New imaging technology allows scientists to peer even deeper into fatty arteries

Researchers from Purdue University, Indiana University School of Medicine, Indiana, USA, and the Shanghai Institute of Optics and Fine Mechanics, Shanghai, China, have improved upon previous instruments, developing a new IVPA catheter design with collinear overlap between optical and acoustic waves with a tiny probe. The design can greatly improve the sensitivity and imaging depth of IVPA imaging, revealing fatty arteries in all of their unctuous detail.
