Liver Calibration Phantoms
The LLNL torso phantom livers (PL-501 through PL-506) are 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. The phantom livers are listed in Liver-nCi and Liver-kBq.

PL-506
PL-506 originally contained 88Y, which has since decayed out.
