摘要

A computed tomography system has a support stage constructed and arranged to support a subject while under observation, an x-ray illumination system arranged proximate the support stage to illuminate the subject with x-rays, an x-ray detection system arranged proximate the support stage to detect x-rays after they pass through the subject and to provide signals based on the detected x-rays, and a data processing system in communication with the x-ray detection system to receive the signals from the x-ray detection system. The computed tomography system has a dynamic mode of operation and a scanning mode of operation. The data processing system extracts information concerning a dynamic process of the subject based on signals from both the dynamic mode and the scanning mode of operation.
