Paper Abstract

X-ray induced acoustic (XA) imaging is novel biomedical imaging technology that can potentially provide an X-ray absorption contrast with high resolution and relatively low dose. In this study, we improved the XA computed tomography (XACT) system using a pulsed X-ray source and a 96-element arc shaped transducer array to provide volumetric images in phantoms. The volumetric XACT images were reconstructed by custom developed software based on a back projection algorithm accelerated by a graphics processor unit (GPU). Using the developed system and software, we successfully acquired the volumetric XACT images of lead targets.
