The Graves Phantom, developed in collaboration with Dr. Stephen Graves (University of Iowa), is designed for quantitative SPECT (qSPECT) calibration and dosimetry in radiopharmaceutical therapy.
Made from water-equivalent Solid Water, it realistically simulates soft tissue attenuation and scatter in a cylindrical geometry.
It provides a simple, reproducible, and AAPM Task Group 417 compliant method to convert counts to activity.
Unlike point or line sources, it delivers realistic scatter and avoids contamination of permanent phantoms by using interchangeable 250 ml lab bottles.
Each kit includes six standard 250 ml bottles, which can be filled for various radionuclides, ensuring efficient and reproducible workflows in both clinical practice and RPT trials.
