| 20090041200 | Radiation therapy imaging and delivery utilizing coordinated motion of jaws, gantry, and couch - A method of delivering a radiation therapy treatment plan to a treatment area of a patient. The treatment plan is delivered using a radiation therapy system including a moveable support for supporting a patient, and a gantry moveable relative to the support. The gantry supports a radiation source, a set of jaws having a jaw width and a multi-leaf collimator for modulating the radiation during delivery of the treatment plan. The support is moved during delivery of the treatment plan to the treatment area, and the width of the jaws is dynamically adjusted during delivery of the treatment plan to the treatment area. | 02-12-2009 |
| 20090110145 | METHOD FOR ADAPTING FRACTIONATION OF A RADIATION THERAPY DOSE - A system and method of adapting a radiation therapy treatment plan for a patient by varying the fraction size delivered to the patient on any individual day, based at least partially on the use of daily patient registration (i.e., taking images of the patient before each fraction is delivered to see the position and size of the tumor on that day). The fraction size can be dynamically altered based upon the biology of the tumor. | 04-30-2009 |
| 20090116616 | SYSTEM AND METHOD FOR MOTION ADAPTIVE OPTIMIZATION FOR RADIATION THERAPY DELIVERY - A system and method of optimizing delivery of a radiation therapy treatment. The system optimizes treatment delivery in real-time to take into account a variety of factors, such as patient anatomical and physiological changes (e.g., respiration and other movement, etc.), and machine configuration changes (e.g., beam output factors, couch error, leaf error, etc.). | 05-07-2009 |
| 20090252291 | SYSTEM AND METHOD FOR MOTION ADAPTIVE OPTIMIZATION FOR RADIATION THERAPY DELIVERY - A system and method of optimizing delivery of a radiation therapy treatment. The system optimizes treatment delivery in real-time to take into account a variety of factors, such as patient anatomical and physiological changes (e.g., respiration and other movement, etc.), and machine configuration changes (e.g., beam output factors, couch error, leaf error, etc.). | 10-08-2009 |
| 20100228116 | SYSTEM AND METHOD OF OPTIMIZING A HETEROGENEOUS RADIATION DOSE TO BE DELIVERED TO A PATIENT - 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. | 09-09-2010 |
| 20110019889 | System and method of applying anatomically-constrained deformation - 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. | 01-27-2011 |
| 20110122997 | NON-VOXEL-BASED BROAD-BEAM (NVBB) ALGORITHM FOR INTENSITY MODULATED RADIATION THERAPY DOSE CALCULATION AND PLAN OPTIMIZATION - A method of calculating a dose distribution for a patient for use in a radiation therapy treatment plan. The method includes acquiring an image of a volume within the patient, defining a radiation source, and defining a reference plane oriented between the radiation source and the patient. The method also includes generating a radiation therapy treatment plan, wherein the plan includes a plurality of rays that extend between the radiation source and the patient volume, and calculating a three-dimensional dose volume for the patient volume from the plurality of rays that intersect the reference plane without first having to independently calculate a dose distribution on each of the plurality of rays. The method can also include displaying the three-dimensional dose volume. | 05-26-2011 |
