Popis:	A new computed tomography imaging device that allows four orders of magnitude improvement in temporal resolution over currently available systems is described. Using 21 simultaneously triggered flash x‐ray sources and 21 detector arrays, density resolution of several percent for a 1‐cm region, lateral spatial projection resolution of 2 mm on a 200‐mm object, and a temporal resolution of 10−6 s are predicted. To achieve this time resolution with only 21 views, both the spatial and contrast resolution are degraded when compared with medical CT systems. The system has multislice capability when used with film/screen detectors. The design, construction, and projected capabilities of the facility are detailed.
