MRI simulation images quality of head and neck coil scanning is better than that of radiotherapy surface coil, but
currently the head and neck coil is not compatible with radiotherapy positioning devices. In this paper, a new fixation
device is developed based on computer reverse engineering technology, which can be used in combination with head
and neck coil. This article focuses on discussing the feasibility of the new device in radiotherapy. The obtained ACR
phantom and Cat phantom 504 images were used to analyze MR and CT images quality assurance indicators. The
dose attenuation of 6 MV photons was measured using the ionization chamber. The results showed each index met
the clinical application requirements of intracranial tumor radiotherapy, thereby it can be used in intracranial tumor
