摘要：
A method of image-guided radiation treatment is described. The method may include acquiring digitally reconstructed radiographs (DRRs) of a patient and generating a first set of image data of part or all of the patient using imaging radiation at a first energy level and a second set of image data of part or all of the patient using imaging radiation at a second energy level, wherein the first energy level is an energy level selected within the range of 50-100 kV and the second energy level is an energy level selected within the range of 100-150 kV. The method ma also include processing the first and second sets of image data to generate an enhanced image, wherein the enhanced image comprises a combination of the first and second sets of image data, and wherein part or all of the image data comprises the target. The method may also include registering the enhanced image with the DRRs to obtain a registration result, tracking movement and position of the target using the registration result to generating tracking information, and directing a treatment delivery beam to the target based on the tracking information obtained from the enhanced image.
