Abstract
Intravascular photoacoustic (IVPA) imaging that aims to detect atherosclerotic plaques with differential composition is studied computationally and experimentally. IVPA images are usually reconstructed by simply aligning photoacoustic signals with scan conversion, which results in images with severe blurring and increases the difficulty in signal detection. The scanning aperture in IVPA, in contrast to other photoacoustic tomography applications, is enclosed within the imaged object. Consequently, quantitative image reconstruction becomes infeasible, as the data sufficiency condition for stable image reconstruction is not satisfied in such a limited-view scanning. However, useful information regarding certain plaque boundaries can still be reconstructed, which can facilitate plaque detection. In this study, strategies for limited-view reconstruction will be investigated for the IVPA scanning geometry. Computer simulations are carried out to validate the developed method.
