Tomography test phantom

for nuclear imagingheart

Overview
The SPECT ACR flangeless phantom (Small Jaszczak SPECT Phantom) is intended to assess the performance of high spatial‑resolution SPECT systems. Recommended by the ACR for small‑FOV cardiac SPECT cameras, it is suitable for acceptance testing, routine quality control and advanced reconstruction and correction studies. It evaluates spatial resolution, uniformity, artifacts, centre‑of‑rotation accuracy and the impact of reconstruction parameters and attenuation/scatter corrections dedicated to cardiac SPECT systems.
