Publication number: 20230248996Abstract: The present application describes a computing system, a computer readable medium, and/or related method for supporting decision making in adaptive therapy. An input interface of receives an input image. A machine learning module predicts, based at least in part on the input image, a dose distribution associated with a first planning technique or a first treatment modality. A comparator compares a planned dose distribution as per a current treatment plan with the predicted dose distribution, to obtain a comparison result. The comparison result enables a user to gauge whether an actual re-planning would yield a dosimetric benefit before committing time or computational resources.Type: ApplicationFiled: July 5, 2021Publication date: August 10, 2023Inventors: MARIA LUIZA BONDAR, ROLF JÜRGEN WEESE, TORBJOERN VIK, TOM BROSCH, JENS WIEGERT, HARALD SEPP HEESE

Patent number: 11147985Abstract: The invention relates to a dynamic sliding-window-like initialization for, for example, iterative VMAT algorithms. Specifically, a dynamic sliding window conversion method is contemplated where typical dynamic VMAT constraints are taken into account to find an optimal set of suitable openings (i.e. binary masks) that can be used as quasi-feasible start initialization for any VMAT algorithm that can refine until a deliverable plan is reached. Here, a multileaf leaf tip trajectory least square constrained optimization is performed to find a set of optimal unidirectional trajectories for all MLC leaf pairs of all arc points. To ensure that a quasi-feasible (or better quasi-deliverable) solution is returned, for example, a maximum dose rate, a maximum gantry speed, a maximum leafs speed, and a maximum treatment time may be enforced.Type: GrantFiled: January 24, 2018Date of Patent: October 19, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Alfonso Agatino Isola, Christoph Neukirchen, Torbjoern Vik, Harald Sepp Heese, Rolf Juergen Weese

Publication number: 20210104026Abstract: Presented are concepts for displaying medical images. One such concept generates transformation data by mapping image data of a medical image to a location in an anatomical atlas and by determining a transfer function for transforming image data of the medical image for display. The transfer function is then associated with the location in the anatomical atlas. A medical image can then be displayed by identifying a transfer function associated with a selected location in the anatomical atlas. The identified transfer function is applied to image data of a medical image that is mapped to the selected location in the anatomical atlas so as to obtain transformed image data. A transformed version of the medical image is then displayed based on the transformed image data.Type: ApplicationFiled: July 30, 2018Publication date: April 8, 2021Inventors: Daniel BYSTROV, Torbjørn VIK, Astrid Ruth FRANZ, Heinrich SCHULZ, Nicole SCHADEWALDT

Patent number: 10548570Abstract: A system and a method are provided for enabling a user to interactively navigate through a set of slice images, the set of slice images jointly representing an image volume showing an anatomical structure of a patient. A user may be enabled to switch from a static viewing mode to a navigation mode based on navigation commands received from a user input device operable by the user. A display processor may be configured for, in the static viewing mode, generating an output image comprising one slice image of the set of slice images. The display processor may be configured for, in the navigation mode, replacing the said one slice image in the output image by a volume rendering of a slab of the image volume, the slab comprising more than one slice image. The system and method thus selectively switch to volume rendering, namely during navigation, whereas in a static (i.e., non-navigation) viewing mode, a slice image is shown.Type: GrantFiled: March 3, 2017Date of Patent: February 4, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Daniel Bystrov, Torbjoern Vik, Astrid Ruth Franz, Harald Sepp Heese, Rafael Wiemker, Dominik Benjamin Kutra
