MULTISPOT X-RAY PHASE-CONTRAST IMAGING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a phase-contrast imaging system having a plurality of X-ray emitters and a method.

SOLUTION: The invention includes a plurality of X-ray emitters for transmitting X-rays through an imaging object to a detector. Adjacent X-ray emitters can 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.
