ABSTRACT:
A system and method for determining the temporal resolution of a tomographic imaging device uses an apparatus to drive one or more dynamic phantoms composed of multiple materials. The apparatus is placed at or near the isocenter of the imaging device and the one or more phantoms are moved to produce a plurality of dynamic features, each having a specified frequency. The dynamic features are imaged with the device and the acquired image data corresponding to the dynamic features is analyzed to determine a temporal modulation transfer value at each of the known specified frequencies. The temporal resolution of the imaging device is determined using these temporal modulation transfer values.
