title = "An intravascular photoacoustic imaging catheter",
abstract = "We developed an integrated intravascular photoacoustic (IVPA) and ultrasound (IVUS) catheter to image atherosclerotic plaque structure and composition, which are important determinants of plaque vulnerability. Our catheter comprises an angle-polished optical fiber and a 30 MHz single-element piezoelectric transducer. The ultrasonic transducer was optically isolated to eliminate artifacts in the photoacoustic (PA) image. We showed its imaging performance using a vessel phantom and quantified its imaging characteristics by doing measurements on isolated point targets. The axial and lateral point spread function widths were 110 m and 550 m respectively for IVPA imaging and 89 m and 420 m respectively for IVUS imaging. The signal to noise ratios were 50 dB (PA) and 54 dB (US).",
