2-D image reconstruction of photoacoustic endoscopic imaging based on time-reversal

摘要

Backgrounds: Photoacoustic endoscopic (PAE) imaging is a rapidly emerging interventional imaging modality for identification and characterization of intraluminal pathological tissues. Since the scanning aperture of PAE is enclosed in the lumen, image reconstruction techniques used in photoacoustic tomography (PAT) can not be directly applied.
