The Research of the Medical Perspective Imaging of Intense Laser Proton Beam

摘要

To research the application of perspective imaging of intense laser proton beam in cytology, experiments are carried out on an ultra-short, ultra-intense picosecond pulsed laser facility, and the results of perspective imaging on biological samples by high energy proton beam, which is excitated among the interaction of picosecond laser with solid target, is showed. The ant is taken as the sample, a high energy proton beam, which is excitated as above on the rear surface of target, makes a 2-dimensional perspective imaging of an ant with high contrast, nanometer spatial resolution and density resolution. The result provided possibility of the application of perspective imaging of intense laser proton beam in cytology.
