Static real-time CT image forming system and image forming method suitable for wide field of view needs

摘要

A static real-time CT image forming system suitable for a wide field of view and an image forming method thereof. The static real-time CT image forming system includes a multifocal ring X-ray source (21) and a ring photon detector (22), and the multifocal ring X-ray source (21) is arranged in a ring. The scanning X-ray source includes a plurality of scanning X-ray sources, and the ring-shaped photon counting detector (22) includes a plurality of photon counting detector modules arranged in a ring shape. Fired in order, projecting to the corresponding photon counting detector module after passing through the subject, the scanning X-ray source and the corresponding photon counting detector module adopt a non-inverted geometric image forming method, Each photon counting detector module operates in an overlapping manner and sends corresponding exposure information to the data acquisition processing unit, where the data acquisition processing unit completes real-time image reconstruction and visual reproduction.
