Liver Calibration Phantom
The LLNL torso phantom liver (PL-501) is molded of solid, muscle-equivalent polyurethane with 3.79 wt% CaCO3. The liver is inserted in an inert tissue-substitute molding called the "liver envelope." The envelope fills spaces in the abdominal cavity of a Torso phantom to simulate the correct anatomical positions of internal organs.

† PL-501 measurement would indicate a slightly higher activity from apparent L x-rays.
