Online-adaptive particle therapy: Current status and vision for the future

In this overview talk the following questions will be addressed: - What
is the status concerning fast adaptations in particle therapy also in
relation to photon therapy?

• Why we need online-adaptive particle therapy (OAPT)?
• What are different approaches also in relation to different adaption

speed?

• What are the different imaging approaches for OAPT?
• How can we verify the treatment delivery when no pre-treatment

phantom QA is performed?

• What is the role of AI-based decision support?
• What initiatives exist on national and international level? Where
