Abstract

Radiation therapy remains a pivotal modality in cancer treatment, relying on precise delineation of tumor targets and surrounding healthy tissues for optimal therapeutic outcomes. Computed Tomography (CT) imaging has become integral to radiation therapy planning, offering detailed anatomical information crucial for treatment precision. This abstract explores the significance of CT integration in radiation therapy planning, emphasizing its role in target delineation, treatment simulation, and dose calculation. Despite its advantages, challenges persist, including limitations in soft tissue delineation, motion artifacts, and the need to balance effective tumor coverage with minimizing collateral damage to healthy tissues. The abstract underscores the importance of addressing these challenges through adaptive planning strategies and the integration of multimodal imaging for enhanced precision. As technology advances, the seamless integration of CT imaging with radiation therapy planning holds the promise of refining cancer treatment strategies and improving patient outcomes.
