Abstract: Objective:To design a kind of head holder for small animal imaging without artifact. Methods: The head holder was designed for small animal imaging according to rodent head stereotaxic apparatus with lightweight and easy molding material (polymethyl methacrylate). The holder can be easily made with ordinary lathe and can be easily operated in small animal imaging device. Results:After the trial in small animal PET-CT, the holder can effectively solve the problems in small animal imaging such as the artifact caused by tiny displacement, tilt head position, deviating from the central field of view and respiratory depression. Conclusion: The small animal imaging device was designed in simple structure to overcome the shortcomings of the existing technology. The operation of the device is simple, which is worthy of popularization head holder of application.
