4D PET-CT guided radiation therapy

Abstract

Tremendous technological progress in the field of imaging and computation have been revolutionizing radiotherapy of non-small cell lung cancer (NSCLC). Tumor biology can now be characterized by functional imaging for modifying treatment management and dose delivered in better accordance with the radiobiology of solid tumors and normal tissues. Specific radiation therapy (RT) strategies can further address the tumor motion issue, ensuring optimal tumor coverage with small safety margins.
