Time-gated medical imaging with ultrafast laser plasma x-rays
Additional Document Info
Laser-generated, hard x-rays are produced in a > 1018W/cm2focus of an ultrashort-pulse laser system. The application of ultrashort-duration, laser-generated x-rays to diagnostic medical imaging is discussed. Time-gated detection allows removal of scattered radiation, improved image quality and possible reduction of patient exposure. Methods for improvement of x-ray yield, design of appropriate drive lasers, and applications to mammography and angiography are also discussed.
