Transmission phantom for total performance assessment of scintillation camera imaging and method of manufacture

摘要

A transmission phantom for total performance assessment of scintillation camera imaging has a constant thickness and at least two layers of homogenous material each layer having different radiation attenuating properties. A layer having a moderate attenuation provides relief areas and a radiation absorbing layer conforming to the relief areas provides for variable transmission through the phantom corresponding to the thickness of the absorbing layer to simulate pathological conditions in a patient. The method of manufacture includes the preparation of a relief mold including a bottom plate and side walls. The radiation absorbing material is poured into the mold, allowed to hardened and milled to a flat surface.
