The Pro-NM ACR Performance Small phantom is designed for performance evaluation of small field-of-view (FOV) NM and PET systems. The phantom enables assessment of key tomographic imaging parameters such as spatial resolution (solid rod insert), cold-spot contrast (set of solid spheres), and tomographic uniformity (uniform region).
The phantom can be used, among other applications, for testing collimators and reconstruction parameters, evaluating imaging artifacts, assessing center-of-rotation error, non-uniformity artifacts, the impact of changes in the radius of rotation on spatial resolution, the effect of reconstruction filters on spatial resolution, as well as the effectiveness of attenuation and scatter correction.
