摘要：
Apparatus for generating multi-energy x-ray images and systems and methods for processing and using multi-energy x-ray images are provided for treating a target, e.g., a tumor, for image-guided radiation therapy. An image-guided radiation therapy system is provided including a treatment delivery system, a multi-energy imaging system, and a system processor. The treatment delivery system includes a radiation source configured to generate treatment radiation beams. The multi-energy imaging system is configured to generate a first set of image data of the patient using imaging radiation at a first energy level and a second set of image data of the patient using imaging radiation at a second energy level. The system processor is configured to process the first and second sets of image data to generate an enhanced image of the patient and to direct the treatment delivery system based on information obtained from the enhanced image.
