a Corresponding attenuation graph generated showing progressive decrease in attenuation from low to high energy levels consistent with calcium composition. b Corresponding attenuation graph generated showing progressive increase in attenuation from low to high energy levels consistent with uric acid composition. C Corresponding attenuation graph generated showing nonlinear change in attenuation suggestive of mixed composition
