Patent number: 11786204Abstract: A three-dimensional model for a patient fixation device that serves to immobilize at least a portion of a particular patient when capturing CT image information of that patient is accessed and then registered with the pixels that correspond to the patient fixation device in the CT image. The model can specify rules of movement for each of a plurality of structural elements that comprise the patient fixation device and that are capable of movement relative to one another. By one approach the aforementioned registration occurs on a part-by-part basis for each of the structural elements. Following registration, the CT image can be automatically segmented.Type: GrantFiled: August 19, 2022Date of Patent: October 17, 2023Assignee: Siemens Heathineers International AGInventors: Armel C.

Patent number: 11679273Abstract: These teachings provide for accessing optimization information comprising at least one isocenter that corresponds to a body outline for a particular patient, field geometry information for a particular radiation treatment platform, and dosimetric data. The optimization information can further comprise a model of a body outline for the patient. A control circuit optimizes a radiation treatment plan as a function of the optimization information to provide an optimized radiation treatment plan where radiation dose levels delivered to the particular patient from a particular field depends on the relative volume magnitude of field path intersections to thereby reduce radiation dose delivery to healthy patient tissue in regions having relatively more overlapping fields.Type: GrantFiled: September 24, 2020Date of Patent: June 20, 2023Assignee: Siemens Healthineers International AGInventors: Juha Kauppinen, Anthony Magliari, Martin Sabel, Amir Talakoub

Publication number: 20230173303Abstract: A method of generating a treatment plan for treating a patient with radiotherapy, the method includes obtaining a plurality of sample plans, which are generated by use of a knowledge base comprising historical treatment plans and patient data. The method also includes performing a multi-criteria optimization based on the plurality of sample plans to construct a Pareto frontier, where the plurality of sample plans are evaluated with at least two objectives measuring qualities of the plurality of sample plans such that treatment plans on the constructed Pareto frontier are Pareto optimal with respect to the objectives. The method further includes identifying a treatment plan by use of the constructed Pareto frontier.Type: ApplicationFiled: January 27, 2023Publication date: June 8, 2023Inventors: Janne NORD, Esa KUUSELA, Joakim PYYRY, Jarkko PELTOLA, Martin SABEL

Patent number: 11406844Abstract: A control circuit accesses topograms of a patient that include patient content that is beyond the portion of the patient that appears in the three-dimensional computed tomography (CT) images for that patient. The control circuit uses those topograms to derive a virtual volumetric structure representing at least some of the patient content that is beyond the aforementioned portion of the patient that appears in the 3D CT images. That virtual volumetric structure can then be used to predict potential collisions when assessing a radiation treatment plan for the patient that utilizes the aforementioned radiation treatment platform. By one approach the topograms include at least two substantially orthographic views of the aforementioned patient content.Type: GrantFiled: March 30, 2020Date of Patent: August 9, 2022Assignee: Varian Medical Systems International AGInventors: Xinhui Yang, Armel C.
