Phase contrast imaging using laser-based hard X-ray source
Abstract
Phase contrast X-ray imaging has been successfuly achieved with hard X-rays generated by the interaction of a high contrast 60fs 10TW 10Hz frequency doubled Ti:Sapphire laser beam with solid targets. Compared to conventional radiography, phase contrast imaging greatly enhances image quality in terms of contrast and resolution, and is of great interest in applications as biomedical imaging. X-ray source produced by a high intensity and high contrast femtosecond laser pulse focused on a solid target gives a sufficient spatial coherence to observe phase contrast. The laser-based X-ray source size, its spectrum and its conversion efficiency were measured, and phase contrast images of several phantoms will be presented and discussed.
