| Abstract: | A way to adopt image intensifier with time-gated MCP or streak camera to detect laser-driven hard-X-ray is described.It has an advantage to reduce the scattering of X-ray,improve the contrast of image,so it is helpful to decrease greatly the X-ray dose adsorbed by body.It can play an important role in X-ray diagnose and X-ray CT diagnose. |
