  • Publication number: 20210038918
    Abstract: A method of image-guided radiation treatment is described. The method may include acquiring a pre-treatment image 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. The method may 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 pre-treatment image to obtain a registration result and tracking movement and position of the target using the registration result to generate tracking information.

  • Patent number: 10843010
    Abstract: 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. The method may 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.

  • Patent number: 9415240
    Abstract: 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.
