AB Accurate tomographic reconstruction of data acquired from rotating scintillation cameras requires strict control of camera field uniformity. Commercially available refillable flood phantoms may develop significant bulging, producing substantial uniformity deviations that may be mistaken for camera nonuniformities, and result in artifacts on reconstructed images. We have developed an iterative method for determining the correct volume of the source, and we have studied the effects of overfilling and underfilling the flood source.
