title: Thermal characteristics of a common polystyrene phantom.
abstract: We have examined the thermal characteristics of a polystyrene phantom of the SCRAD type. In the case of a calibration phantom which is moved from one location to another, many hours may be required to achieve thermal equilibrium with the new environment. By using a correction term based on the temperature of the phantom, not of the room, it is possible to calibrate a therapy unit without waiting for thermal equilibrium.
