Patent number: 12293820Abstract: Systems and methods for cardiac radioablation treatment planning are disclosed. In some examples, a computing device receives an image volume and a dose matrix data. The computing device generates a first mesh of organ substructures for the organ based on substructure contours for the organ. Further, the computing device generates a second mesh of an isodose volume based on the dose matrix data. The computing device displays the first mesh of the organ substructures and the second mesh of the isodose volume within a same scene. In some examples, the computing device samples a plurality of dosage values, determines representative dosage values for each of a plurality of points along surfaces of a dose matrix, and generates an image for display based on the representative dosage values. In some examples, a segmentation model is generated for display based on the representative dosage values.Type: GrantFiled: July 3, 2020Date of Patent: May 6, 2025Assignees: VARIAN MEDICAL SYSTEMS, INC., SIEMENS HEALTHINEERS INTERNATIONAL AGInventors: Leigh Scott Johnson, Patrik Niklaus Kunz, Andrea Morgan, Francesca Attanasi, Stefan Georg Scheib, Jonas Honegger

Patent number: 12283366Abstract: Systems and methods for cardiac radioablation treatment planning are disclosed. In some examples, a computing device receives a first signal identifying a first event within a first workspace from a second computing device. The computing device determines a first action to apply to a first image displayed within a second workspace based on the first signal. The computing device generates a second image based on applying the first action to the first image within the second workspace, and displays the second image within the second workspace. In some examples, the first workspace is a radiation oncologist workspace and the second workspace is an electrophysiologist workspace. In some examples, the first workspace is an electrophysiologist oncologist workspace and the second workspace is a radiation oncologist workspace.Type: GrantFiled: July 3, 2020Date of Patent: April 22, 2025Assignees: VARIAN MEDICAL SYSTEMS, INC., SIEMENS HEALTHINEERS INTERNATIONAL AGInventors: Leigh Scott Johnson, Jonas Michael Honegger, Patrik Niklaus Kunz, Stefan Georg Scheib, Francesca Attanasi, Andrea Morgan

Patent number: 11878189Abstract: A computer-implemented method of performing a treatment fraction of radiation therapy comprises: determining a current position of a target volume of patient anatomy; based on the current position of the target volume, computing an accumulated dose for non-target tissue proximate the target volume; determining that the accumulated dose is less than a current value for a dose budget of the non-target tissue; and in response to the accumulated dose being less than the current value for the dose budget, applying a treatment beam to the target volume while the target volume is in the current position.Type: GrantFiled: August 31, 2022Date of Patent: January 23, 2024Assignee: SIEMENS HEALTHINEEERS INTERNATIONAL AGInventors: Nasim Givehchi, Claas Wessels, Toon Roggen, Pascal Paysan, Marius Heinrich Walter Koehl, Stefan Georg Scheib

Publication number: 20230282320Abstract: Provided herein are methods and systems to train and execute a motion model that uses artificial intelligence methodologies (e.g., deep-learning) to learn and predict location of a patient's internal structures. A method comprises receiving respiratory data of a patient from an electronic sensor in addition to a medical image, such as kV image; executing an artificial intelligence model using the respiratory data and predicting deformation data for at least one internal structure of the patient, wherein the artificial intelligence model is trained in accordance with a training dataset comprising a set of participants, their corresponding respiratory data, and their corresponding deformation data; and outputting the predicted deformation data.Type: ApplicationFiled: March 7, 2022Publication date: September 7, 2023Applicant: Varian Medical Systems International AGInventors: Ricky R. Savjani, Pascal Paysan, Stefan Georg Scheib

Patent number: 11027153Abstract: A radiation therapy system is configured to enable imaging and treatment of a target volume during a single patient breath hold. The radiation system includes a rotating gantry on which are mounted a treatment-delivering X-ray source and multiple imaging X-ray sources and corresponding X-ray imaging devices. The multiple imaging X-ray sources and X-ray imaging devices enable the acquisition of volumetric image data for the target volume over a relatively short rotational arc, for example 30 degrees or less. Therefore, intra-fraction motion can be detected in near-real time, for example within about one second or less. The radiation therapy system can perform image guided radiation therapy (IGRT) that monitors intra-fraction motion using X-ray imaging. Detected anatomical variations can then either be compensated for, via patient repositioning and/or treatment modification, or the current treatment can be aborted.Type: GrantFiled: June 25, 2019Date of Patent: June 8, 2021Assignee: VARIAN MEDICAL SYSTEMS, INC.Inventors: John Van Heteren, Liangjia Zhu, Daniel Morf, Stefan Georg Scheib, Pascal Paysan
