Abstract
X-ray computed tomography has emerged as a versatile tool in biology, biomedicine, and materials science, providing high-resolution three-dimensional images. However, high-resolution imaging typically requires the use of specialized sources and detectors, and long scan times---plus the delivery of high doses of radiation. The authors develop an imaging concept for x-ray computed tomography that allows high resolution with ``low-resolution'' equipment, in much less time, and without a significant dose increase. This approach is expected to provide advantages in $e.g.$ preclinical imaging, where longitudinal studies in small animals currently are severely restricted by dose constraints.
