METHOD AND SYSTEM FOR X-RAY RADIATION IMAGING

摘要

A method for X-ray imaging with pulsed X-ray source, X-ray detector (11) suitable for that source and synchronized detector gated current integration sampling and readout electronic circuit (13), that can be used to increase signal-to-noise ratio on X-ray images taken using same X-ray dose or to decrease X-ray dose needed to observe same signal-to-noise ratio on X-ray images Signal to noise ratio is improved since integration time for the detector current is shorter so less charge produced by leakage current of the detector is integrated.
