5. Verification of high energy photon therapy based on PET/CT imaging of photonuclear reactions
Abstract : For classical and intensity modulated radiation therapy of deep-seated tumors, high-energy photons are the optimal radiation modality from an integral dose point of view. By using narrow scanned beams the treatment outcome can be improved substantially by delivering biologically optimized intensity modulated distributions often with sharp dose gradients. READ MORE
