Quantitative photoacoustic imaging of simulated carotid plaques in a neck phantom

Timely, accurate assessment of atherosclerotic plaque composition in the carotid arteries to enable prevention of ischaemic stroke is currently an important topic in medical imaging. Photoacoustic imaging, which lacks ionizing radiation and foreign contrast agents, is attracting much interest in the field of non-invasive carotid plaque imaging. We present results of the characterization of our new system, based on a concave ultrasound transducer and optical fibre illumination, as well as multi-wavelength photoacoustic images of a PVCP-based phantom, supplemented with ultrasound plane wave images. The multi-wavelength photoacoustic imaging capability of the probe has potential for eventual carotid plaque imaging and quantification.
