Abstract:
This invention describes a dynamic X-ray imaging system for small animal studies and other applications that include a volumetric CT fluoroscopy (VCTF) scanner and software, which operates in accordance with a generalized Feldkamp algorithm or any other suitable reconstruction methods. The VCTF system is a significant advancement of current micro-CT techniques. While prior micro-CT systems are featured by relatively slow data acquisition and static image reconstructions, the present invention includes real-time data acquisition hardware, a dedicated real-time image reconstruction algorithm, an extra-fast cone-beam reconstruction engine, and integrating them into a 4D micro-CT scanner. The system of the present invention can be constructed relatively economically using state-of-the-art x-ray source, electronic detector techniques and image reconstruction methods.
