adaptive radiation therapy
Treatment approach that modifies radiation plans during treatment course based on anatomical or biological changes.
Full Definition
Adaptive radiation therapy represents an advanced treatment paradigm that systematically modifies radiation therapy plans during the course of treatment to account for changes in patient anatomy, tumor response, or normal tissue positioning. This approach utilizes repeated imaging, often daily, to detect significant changes in target volume size, shape, or position, triggering plan modifications to maintain treatment accuracy and effectiveness. Adaptive radiation therapy can be implemented offline with formal replanning or online with real-time adjustments, representing a significant advancement toward personalized radiation medicine.
Usage
Usage note: Often abbreviated as ART; maintain lowercase for 'radiation therapy' component.
