Abstract: The present invention relates to a phantom for use in the auditing or verification of a proposed radiation therapy regime for administration to a patient. The phantom comprises a housing which is shaped to simulate the anatomical shape of a human head and neck; and a radiation detector module configured to receive at least one radiation detector. The housing defines a cavity in which the radiation detector module can be removeably received such that the radiation detector module occupies a predetermined location within the simulated head and neck of the housing. Said predetermined location encompasses areas of the housing which simulate a target site to which it is proposed to administer radiation to the patient and a location of at least one organ that is susceptible to harm by administration of said radiation.
