The present disclosure provides a system for imaging via an imaging device including a plurality of radiation sources. Each of at least a portion of the plurality of radiation sources may be configured with a beam stop array that is configured to block at least a portion of radiation beams emitted by the radiation source. For one of the at least a portion of the plurality of radiation sources, the system may determine, based on a scatter distribution, first image data, and second image data, third image data of a subject corresponding to each of the at least a portion of the plurality of radiation sources. For each of at least a portion of the plurality of radiation sources, the system may further determine, based on image data of the subject, target image data of the subject using a calibration model.

Systems and methods for X-ray imaging

A method include obtaining original projection data of an object. The original projection data may be acquired by scanning the object using a radiation device from one or more projection views. The original projection data may include truncation projection data that is acquired from at least one of the one or more projection views. In each of the at least one of the one or more projection views a truncation region of the object may be located outside an FOV of the radiation device. The method may include obtaining a target S-shaped extrapolation function based on the original projection data. The method may include determining, based on the target S-shaped extrapolation function and the original projection data, extended projection data corresponding to the at least one truncation region. The method may include generating an image of the object based on the original projection data and the extended projection data.
