Siemens Healthineers AI Radiotherapy Modulation Patent EP4711001A1
Summary
The European Patent Office has published patent EP4711001A1 for Siemens Healthineers, detailing systems and methods that use artificial intelligence to control modulation in radiotherapy plans. This patent aims to optimize treatment planning by incorporating AI-driven dose distribution and regularization factors.
What changed
European patent EP4711001A1, published on March 18, 2026, describes a novel approach by Siemens Healthineers International AG for modulating radiotherapy plans using artificial intelligence. The disclosed methods and systems (100) involve receiving plan objectives, establishing dose distribution parameters, initializing regularization factors, and generating a treatment plan objective that incorporates weighted components. This AI-generated objective is then transmitted to a radiotherapy treatment planning computer model to determine the final treatment plan (440).
This patent introduces a new technological capability for optimizing radiotherapy treatments. While it is a patent and not a direct regulatory mandate, it signals advancements in AI applications within healthcare. Compliance officers in the medical device and pharmaceutical sectors should be aware of such technological developments, as they may influence future product development, regulatory submissions, and clinical practice standards in radiation oncology. No immediate compliance actions are required, but monitoring AI integration in medical devices is advisable.

Abstract
Disclosed herein are methods (200) and systems (100) using artificial intelligence models (420) to control the amount of modulation in radiotherapy plans (440). The system (100) may receive (210) parameters defining a plan objective for a radiotherapy treatment plan (440). The system (100) may establish (220) dose distribution parameters for each field of the plan objective. The system (100) may initialize (230) user-defined field regularization factors for each field of the plan objective. The system (100) may initialize (240) plan regularization factors. In response to applying the user-defined field regularization factor to a corresponding field of the plan objective and the plan regularization factor to the plan objective, the system (100) may generate (250) a treatment plan objective incorporating weighted components for the plan objective and each field. The system (100) may transmit (260) the treatment plan objective to a radiotherapy treatment planning computer model. The radiotherapy treatment planning computer model may determine the radiotherapy treatment plan (440) based on the treatment plan objective.
