Patent number: 11941544Abstract: Nominal values of parameters, and perturbations of the nominal values, that are associated with previously defined radiation treatment plans are accessed. For each treatment field of the treatment plans, a field-specific planning target volume (fsPTV) is determined based on those perturbations. At least one clinical target volume (CTV) and at least one organ-at-risk (OAR) volume are also delineated. Each OAR includes at least one sub-volume that is delineated based on spatial relationships between each OAR and the CTV and the fsPTV for each treatment field. Dose distributions for the sub-volumes are determined based on the nominal values and the perturbations. One or more dose prediction models are generated for each sub-volume. The dose prediction model(s) are trained using the dose distributions.Type: GrantFiled: December 22, 2022Date of Patent: March 26, 2024Assignee: SIEMENS HEALTHINEERS INTERNATIONAL AGInventors: Perttu Niemela, Jari Lindberg, Tuomas Jyske, Maria Cordero Marcos, Esa Kuusela

Patent number: 11738211Abstract: A system for estimating a dose from a proton therapy plan includes a memory that stores machine instructions and a processor coupled to the memory that executes the machine instructions to subdivide a representation of a volume of interest in a patient anatomy traversed by a planned proton field into a plurality of voxels. User input received by a GUI can be used to define the representation. The processor further executes the machine instructions to determine the distance from the source of the planned proton beam to one of the voxels. The processor also executes the machine instructions to compute the discrete contribution at the voxel to an estimated dose received by the volume of interest from the planned proton beam based on the distance between the source and the volume of interest.Type: GrantFiled: November 24, 2020Date of Patent: August 29, 2023Assignee: SIEMENS HEALTHINEERS INTERNATIONAL AGInventors: Esa Kuusela, Maria Cordero Marcos, Janne Nord

Publication number: 20210327593Abstract: System and method for automatically generate therapy plan parameters by use of an integrate model with extended applicable regions. The integrated model integrates multiple predictive models from which a suitable predictive model can be selected automatically to perform prediction for a new patient case. The integrated model may operate to evaluate prediction results generated by each predictive model and the associated prediction reliabilities and selectively output a satisfactory prediction. Alternatively, the integrated model may select a suitable predictive model by a decision hierarchy in which each level corresponds to divisions of a patient data feature set and divisions on a subordinate level are nested with divisions on a superordinate level.Type: ApplicationFiled: June 24, 2021Publication date: October 21, 2021Inventors: Esa KUUSELA, Maria CORDERO MARCOS, Joona HARTMAN, Jarkko Y PELTOLA, Janne I NORD

Patent number: 10653893Abstract: A control circuit provides an opportunity via a user interface for a user to specify at least one custom DVH estimation model training feature. The control circuit then combines a predetermined set of DVH estimation model training features with a user-specified customer DVH estimation model training feature to provide a combined feature set. The control circuit uses the combined feature set to train a knowledge-based DVH estimation model which is then used to provide a DVH estimation for use when developing/optimizing a radiation treatment plan. That resultant radiation treatment plan then controls a radiation-administration platform to provide a therapeutic radiation dose to a patient.Type: GrantFiled: August 30, 2017Date of Patent: May 19, 2020Assignee: Varian Medical Systems International AGInventors: Esa Kuusela, Maria Cordero Marcos, Hannu Laaksonen

Patent number: 10159851Abstract: The present invention proposes a method for automatically training a dose prediction model based on existing clinical knowledge that is accumulated from multiple sources without collaborators establishing communication links between each other. According to embodiments of the claimed subject matter, clinics can collaborate in creating a dose prediction model by submitting their treatment plans into a remote computer system (such as a cloud-based system) which aggregates information from various collaborators and produces a model that captures clinical information from all submitted treatment plans, and can be used to predict dose distributions (and other dose parameters) in subsequent treatment plans.Type: GrantFiled: July 5, 2016Date of Patent: December 25, 2018Assignee: Varian Medical Systems International SGInventors: Joona Hartman, Maria Cordero Marcos, Esa Kuusela, Jarkko Peltola, Janne Nord
