Highly Sensitive Intravascular Photoacoustic Imaging with a Collinear Catheter Probe

Not Accessible

Your library or personal account may give you access

Abstract

A collinear catheter for label-free intravascular photoacoustic imaging was developed with a diameter of 1.6 mm. The collinear overlap between optical and acoustic waves enabled photoacoustic imaging of a human coronary artery from lumen to perivascular fat.
