Tomography test phantom

for nuclear imagingthoraxlung

Description
The elliptical lung–spine phantom is designed to simulate anatomical structures and radioactivity distributions of the human upper thorax. It includes fillable lung inserts and a spine insert, enabling realistic evaluation of acquisition and reconstruction methods in cardiac and pulmonary imaging. The phantom is particularly suited to analyze non-uniform attenuation and scatter effects in ECT and SPECT studies and for advanced research work.
