    摘要： System and method of generating a warp field to generate a deformed image. The system and method use segmentation in a new method of image deformation with the intent of improving the anatomical significance of the results. Instead of allowing each image voxel to move in any direction, only a few anatomical motions are permissible. The planning image and the daily image are both segmented automatically. These segmentations are then analyzed to define the values of the few anatomical parameters that govern the allowable motions. Given these model parameters, a deformation or warp field is generated directly without iteration. The warp field is applied to the planning image or the daily image to deform the image. The deformed image can be displayed to a user.

    摘要： A system and method of evaluating dose delivered by a radiation therapy system using a marker that indicates motion. The marker is associated with the patient. In one method of operation, the method includes delivering radiation to the patient, monitoring motion of the marker during the delivering radiation, and evaluating a dose delivered to the patient based at least in part on the motion of the marker. In another method of operation, the method includes delivering radiation to the patient, obtaining information relating to the delivery of radiation, estimating dose to the marker based at least in part on the information, acquiring dose received by the marker, and comparing the received dose with the estimated dose.

    摘要： A radiation therapy treatment system and method of optimizing a heterogeneous dose to be delivered to a patient. The system includes a computer processor and a software program stored in a computer readable medium accessible by the computer processor. The software program is operable to receive a prescribed heterogeneous radiation dose to be delivered to the patient, determine a homogeneous reference dose, calculate a complementary radiation dose by determining a difference between the homogeneous reference dose and the heterogeneous radiation dose, generate a treatment plan for the patient, the treatment plan including an optimized radiation dose to be delivered to the patient, combine the complementary radiation dose and the optimized radiation dose, evaluate the combined radiation dose with respect to the homogeneous reference dose, and display the combined radiation dose.
