X-RAY IMAGING APPARATUS AND METHOD FOR REDUCING X-RAY SCATTERING
摘要:
An X-ray imaging apparatus and method for reducing X-ray scattering are provided. The X-ray imaging apparatus includes an X-ray source, a collimator, a detector, and a controller. The X-ray source emits X-rays, the collimator collimates the X-rays into an X-ray beam, and the detector may include a two-dimensional array of pixels. The controller controls the collimator such that the X-ray beam scans a subject while moving over time. In addition, the controller operates the detector to only operate pixels at an exposure area of the detector where the X-ray beam arrives without scattering such that photocharges generated due to the X-ray exposure can be accumulated and stored in the pixels.
