摘要:
Ultralow-dose, x-ray or gamma-ray imaging is based on fast, electronic control of the output of a laser-Compton x-ray or gamma-ray source (LCXS or LCGS). X-ray or gamma-ray shadowgraphs are constructed one (or a few) pixel(s) at a time by monitoring the LCXS or LCGS beam energy required at each pixel of the object to achieve a threshold level of detectability at the detector. An example provides that once the threshold for detection is reached, an electronic or optical signal is sent to the LCXS/LCGS that enables a fast optical switch that diverts, either in space or time the laser pulses used to create Compton photons. In this way, one prevents the object from being exposed to any further Compton x-rays or gamma-rays until either the laser-Compton beam or the object are moved so that a new pixel location may be illumination.
摘要(中):
超低剂量,x射线或γ射线成像基于快速电子控制激光康普顿X射线或伽马射线源(LCXS或LCGS)的输出。 通过监测物体的每个像素所需的LCXS或LCGS光束能量,以便在检测器处获得阈值水平的检测能力,一次构建X射线或γ射线阴影片一个(或几个)像素。 一个例子提供,一旦达到检测阈值,就会向LCXS / LCGS发送一个电子信号或光信号,该信号使得能够在空间或时间上转移用于产生康普顿光子的激光脉冲的快速光学开关。 以这种方式,可以防止物体暴露于任何其他康普顿X射线或伽马射线,直到激光康普顿光束或物体移动,使得新的像素位置可以是照明。
