Improved synthetic aperture focusing technique for acoustic-resolution photoacoustic microscopy

Abstract

Acoustic-resolution photoacoustic microscopy (AR-PAM) capable of imaging micro-vessels with high resolution and high contrast has shown its potential in functional neuro-vascular imaging, dermatology and related cancer research. In AR-PAM, a mechanically scanned, single crystal transducer with a fixed focus is commonly used, which causes the image quality… (More)
