| Number | Title | Issue Date |
| 7860550 | Patient positioning assembly A robotic patient positioning assembly for therapeutic radiation treatment includes a robotic positioning device for moving and supporting the patient during treatment, a sensor system for detecting the position of the robotic positioning device, and a controller op... | 12/28/2010 |
| 7840093 | Image enhancement method and system for fiducial-less tracking of treatment targets A method and system are presented for enhancing one or more images of an object, so as to increase the visibility within the images of one or more structures within the object. The object may be an anatomical region of a patient, and may include one or more referenc... | 11/23/2010 |

The object may be an anatomical region of a patient, and may include one or more referenc... | 04/21/2009 |
| 7505617 | Fiducial-less tracking with non-rigid image registration A method and system is presented for tracking patient motion in image guided surgery, using skeletal reference structures instead of fiducial markers. ... | 03/17/2009 |
| 7505037 | Direct volume rendering of 4D deformable volume images A method and system are presented for direct volume rendering of a deformable volume dataset that represent an object in motion. An original 3D image dataset of the object is acquired at an initial stage of the motion, and segmented. Deformed 3D image datasets of th... | 03/17/2009 |
| 7480399 | Apparatus and method for determining measure of similarity between images A method and system is presented in image-guided radiosurgery for determining the measure of similarity of two digital images, for example a 2D x-ray image and a 2D DRR synthesized from 3D scan data. A two-dimensional array of pixel values of a difference image may ... | 01/20/2009 |
