Patent number: 9474914Abstract: Treatment targets such as tumors or lesions, located within an anatomical region that undergoes motion (which may be periodic with cycle P) are tracked. A 4D mathematical model may be established for the non-rigid motion and deformation of the anatomical region, from a set of CT or other 3D images. The 4D mathematical model relates the 3D locations of part(s) of the anatomical region with the targets being tracked, as a function of the position in time within P. Using non-rigid image registration between pre-operative and intra-operative images, the position of the target and/or other part(s) of the anatomical region may be determined.Type: GrantFiled: March 10, 2015Date of Patent: October 25, 2016Assignee: Accuray IncorporatedInventors: Euan S. Thomson, John Dooley, Gopinath Kuduvalli, James Wang, Eric Earnst, Chris Raanes

Patent number: 8989349Abstract: Treatment targets such as tumors or lesions, located within an anatomical region that undergoes motion (which may be periodic with cycle P), are dynamically tracked. A 4D mathematical model is established for the non-rigid motion and deformation of the anatomical region, from a set of CT or other 3D images. The 4D mathematical model relates the 3D locations of part(s) of the anatomical region with the targets being tracked, as a function of the position in time within P. Using fiducial-less non-rigid image registration between pre-operative DRRs and intra-operative x-ray images, the absolute position of the target and/or other part(s) of the anatomical region is determined. The cycle P is determined using motion sensors such as surface markers. The radiation beams are delivered using: 1) the results of non-rigid image registration; 2) the 4D model; and 3) the position in time within P.Type: GrantFiled: September 30, 2004Date of Patent: March 24, 2015Assignee: Accuray, Inc.Inventors: Euan Thomson, John Robinson Dooley, Gopinath Kuduvalli, James Wang, Eric Earnst, Chris Raanes

Patent number: 7860550Abstract: 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 operatively connected with the sensor system for receiving position data of the robotic positioning device and operatively connected to the robotic positioning device for controlling the motions of the robotic positioning device. The controller is adapted for controlling the motion of the robotic positioning device in response to information representative of the position of the robotic positioning device received from the sensor system, so that the treatment target within a patient loaded on the robotic positioning device is properly aligned with a radiation source of a therapeutic radiation treatment system.Type: GrantFiled: June 30, 2004Date of Patent: December 28, 2010Assignee: Accuray, Inc.Inventors: Michael Saracen, James Wang, Euan Thomson, Eric Earnst, Chris Raanes, Mohan Bodduluri

Patent number: 7656998Abstract: A unified quality assurance technique to verify alignment of a radiation treatment delivery system. In one embodiment, a radiation treatment source is instructed to move to a preset source position. An image of the radiation treatment source at its actual source position is generated and compared against a reference image to determine whether the radiation treatment source correctly achieved the preset source position. In one embodiment, a positioning system is instructed to move a target detector to a preset target position. An image of the target detector at its actual target position is generated and compared against a reference target image to determine whether the positioning system correctly achieved the preset target position.Type: GrantFiled: November 14, 2005Date of Patent: February 2, 2010Assignee: Accuray IncorporatedInventors: William T. Main, Eric Earnst, Gopinath Kuduvalli

Patent number: 7604405Abstract: A method and apparatus for quality assurance of an image guided radiation treatment delivery system. A quality assurance (“QA”) marker is positioned at a preset position under guidance of an imaging guidance system of a radiation treatment delivery system. A radiation beam is emitted from a radiation source of the radiation treatment delivery system at the QA marker. An exposure image of the QA marker due to the radiation beam is generated. The exposure image is then analyzed to determine whether the radiation treatment delivery system is aligned.Type: GrantFiled: February 14, 2008Date of Patent: October 20, 2009Assignee: Accuray IncorporatedInventors: William Main, Eric Earnst, Gopinath Kuduvalli
