Patent number: 11854761Abstract: Presented systems and methods facilitate efficient and effective generation and delivery of radiation. A radiation generation system can comprise: a particle beam gun, a high energy dissipation anode target (HEDAT); and a liquid anode control component. In some embodiments, the particle beam gun generates an electron beam. The HEDAT includes a solid anode portion (HEDAT-SAP) and a liquid anode portion (HEDAT-LAP) that are configured to receive the electron beam, absorb energy from the electron beam, generate a radiation beam, and dissipate heat. The radiation beam can include photons that can have radiation characteristics (e.g., X-ray wavelength, ionizing capability, etc.). The liquid anode control component can control a liquid anode flow to the HEDAT. The HEDAT-SAP and HEDAT-LAP can cooperatively operate in radiation generation and their configuration can be selected based upon contribution of respective HEDAT-SAP and the HEDAT-LAP characteristics to radiation generation.Type: GrantFiled: April 25, 2022Date of Patent: December 26, 2023Assignee: VARIAN MEDICAL SYSTEMS, INC.Inventors: Josh Star-Lack, James Clayton

Patent number: 11173324Abstract: Reconstruction of projection images of a CBCT scan is performed by generating simulated projection data, comparing the simulated projection data to the projection images of the CBCT scan, determining a residual volume based on the comparison, and using the residual volume to determine an accurate reconstructed volume. The reconstructed volume can be used to segment a tumor (and potentially one or more organs) and align the tumor to a planning volume (e.g., from a CT scan) to identify changes, such as shape of the tumor and proximity of the tumor to an organ. These changes can be used to update a radiation therapy procedure, such as by altering a radiation treatment plan and fine-tuning a patient position.Type: GrantFiled: April 13, 2018Date of Patent: November 16, 2021Assignees: VARIAN MEDICAL SYSTEMS, INC.Inventors: Pascal Paysan, Marcus Brehm, Adam Wang, Dieter Seghers, Josh Star-Lack

Patent number: 10967202Abstract: A method of generating an image synthesis process is disclosed, where the image synthesis process improves image quality of degraded volumetric images. In the method, a machine learning process is trained in a supervised learning framework as the image synthesis process. In the supervised learning process, a lower-quality partial-data reconstruction of a target volume is employed as an input object in the supervised learning process and a higher-quality full data reconstruction of the target volume is employed as an expected output. The full data reconstruction is generated based on a first set of projection images of the three-dimensional volume and the partial-data reconstruction is generated based on a second set of projection images of the three-dimensional volume, where the second set of projection images includes projection images that have less image information and/or are of a lower image quality than the first set of projection images.Type: GrantFiled: June 4, 2019Date of Patent: April 6, 2021Assignee: VARIAN MEDICAL SYSTEMS, INC.Inventors: John Van Heteren, Petr Jordan, Adam Wang, Josh Star-Lack

Patent number: 10960232Abstract: A radiation therapy system delivers radiation treatment over a 360-degree arc and performs a prepended imaging process, in a single pass, via an extended rotation gantry. While rotating the gantry in one direction about a bore of the radiation system, the radiation system generates multiple images of a target volume disposed in the bore using an imaging X-ray source mounted on the gantry. Then, while continuing to rotate the gantry in the same direction, the radiation system delivers a treatment beam to the target volume using a treatment-delivering X-ray source mounted on the gantry, where the treatment beam is delivered from some or all of a 360-degree arc about the bore. Thus, the prepended imaging process and the delivery of radiation are performed in a single pass of the gantry about a target volume, eliminating the need for a return stroke of the gantry for completion.Type: GrantFiled: November 5, 2018Date of Patent: March 30, 2021Assignee: VARIAN MEDICAL SYSTEMS, INC.Inventors: Blake Gaderlund, Josh Star-Lack, John Van Heteren, Adam Wang
