SUPPORTING RADIATION THERAPY PLANNING

1 . A computing system for supporting radiation therapy planning, the system comprising:

an input interface for receiving input radiation treatment plan templates, or types of such plan templates, for plural radiation treatment plans, and

a trained machine learning model configured to compute plural dose maps associated with the received radiation treatment plan templates or with the types of such plan templates.

2 . System of claim 1 , wherein the input interface is arranged as a user interface configured to allow a user to select the input radiation treatment plan template or type.

3 . System of claim 2 , wherein the input interface is configured to allow selection of any one or more of the input templates and the plural dose maps are computed by the trained machine learning model in response to such selection.

4 . System of claim 1 , further comprising an output navigation user interface, configured to allow a user to navigate through the output plural dose maps and select a dose map from among the plural dose maps.

5 . System of claim 3 , wherein the output navigation user interface and/or the input interface is arranged as a graphical user interface.

6 . System of claim 1 , wherein the trained machine learning model is of the generative type.

7 . System of claim 1 , wherein the templates include data that relates to different clinical goals.

8 . System of claim 6 , wherein the said clinical goals includes any one or more of: i) different clinical dose upper limits for one or more organs at risks, ii) different dose lower limits for a target, iii) different trade-offs between target coverage and organ-at-risk sparing iv) different treatment parameters.

9 . System of claim 1 , including a radiation therapy planning module configured to generate a treatment plan based on the dose map selected by the user via the output navigation interface.

10 . A training system configured to train a machine learning model based on training data to obtain the trained model of the system of claim 1 .

11 . A radiation treatment arrangement, including a planning system, a system of claim 1 , and/or a treatment delivery device.

12 . A computer-implemented method for supporting radiation therapy planning, the method comprising:

receiving input radiation treatment plan templates, or types of such plan templates, for plural radiation treatment plans, and

computing by a trained machine learning model plural dose maps associated with the received radiation treatment plan templates or with the types of such plan templates.

13 . Method for training a machine learning model based on training data to obtain the trained model in the system of claim 1 .

14 . A computer program element, which, when being executed by at least one processing unit, is adapted to cause the at least one processing unit to perform the method as per claim 12 .

15 . At least one computer readable medium having stored thereon the program element of claim 14 .
