Highly Sensitive Intravascular Photoacoustic Imaging with a Collinear Catheter Probe

Abstract

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.OCIS codes: (110.5120) Photoacoustic imaging; (120.4570) Optical design of instruments.
