Rigidly indexed apparatus for external beam radiotherapy positioning of small animals

Abstract

To aid in the positioning of animals, such as cats and dogs, during radiotherapy treatment, a device can be indexed on a standard U-Frame. The device includes indexing holes that align with pins of the U-Frame. Based on the size of the animal, the indexing pins can be placed so the portions of the animal (e.g., head or neck) under treatment receive the radiotherapy directly. The device keeps the mouth of the animal open in a manner to further locate the animal and to aid in placement of breathing apparatus for the animal under anesthesia. The device can be sized for different sizes of animals and can also include features such as dosing meters to mitigate over treatment of the radiation used for the treatment.
