MULTISPOT X-RAY PHASE-CONTRAST IMAGING SYSTEM

摘要

A phase-contrast imaging system and method. An embodiment of the invention includes a plurality of X-ray emitters for transmitting X-rays through an object to a detector. Adjacent X-ray emitters may be activated at different times to prevent confounding of X-ray striking on the detector. Each X-ray emitter can be operated independently to provide different flux outputs for reducing overall patient dose.
