title: A CT-based simulation for head and neck tumors in centers without CT-simulator and 3D-planning system.
abstract: We present a special CT-based simulation technique to optimize the radiotherapy treatments in head and neck tumors. On an immobilization device, some CT hyperdense markers are placed. Real-size CT slices are performed every 5 mm with the patient in the treatment position with the immobilization system. This study permits a more accurate knowledge of the gross tumoral volume and an optimization of the planning treatment.
