A dual-energy Compton scatter imaging technique, analogous to that used in computed tomography and conventional radiography, has been explored. It is shown that this technique allows the photoelectric component of the attenuation factors for the primary and scattered radiations to be derived. Compton scatter images of the ear, corrected for photo-attenuation using dual energy, have been obtained with a novel Compton scatter scanner (Comscan) and are presented here. In addition, dual-energy Compton scatter imaging allows photo-effect slice images to be obtained which are a useful extension to the customary Compton images. The application of dual-energy Compton scatter to imaging bony structures and densitometry is illustrated.
一种类似于计算机断层扫描和传统放射成像中所使用的双能康普顿散射成像技术已被探索。结果表明，该技术能够推导初级辐射和散射辐射衰减因子的光电分量。使用新型康普顿散射扫描仪（Comscan）已获得了经双能校正光衰减后的耳部康普顿散射图像，并在此展示。此外，双能康普顿散射成像能够获取光效应切片图像，这是对传统康普顿图像的有益扩展。文中阐述了双能康普顿散射在骨结构成像和骨密度测定中的应用。
