Abstract

Dynamic reconstruction is a method for generating images or image sequences from data obtained using moving radiation detection systems. While coded apertures are used as examples of the underlying information collection modality, the dynamic reconstruction method itself is more widely applicable. Dynamic reconstruction provides for recovery of depth, and has sensitivity that drops off with the inverse of distance rather than the inverse square of distance. Examples of dynamic reconstructions of moving isotopic area sources are shown, as well as dynamic reconstructions of moving objects imaged using backscattered X-rays.
