Precise target delineation and safety margin definitions are mandatory in radiation treatment of head and neck tumors. In this context, magnetic resonance imaging (MRI) is increasingly used in addition to computed tomography (CT) in the treatment planning system because of its superior soft tissue contrast. In this work, a novel 16 channel head and neck array coil is presented, which is adapted to the special requirements of radiotherapy planning. It allows for MR imaging of patients with brain and head and neck tumors in treatment planning position in individual immobilization masks.
