WORLDWIDE REFERENCE STANDARD FOR IN-VIVO COUNTING
The Lawrence Livermore Realistic Phantom was developed under the direction of the U.S Department of Energy, primarily as a reference standard for the in vivo counting of emissions from low-energy transuranic nuclides.
The organs of interest are the lungs, liver and lymph nodes. Each of these may be radioactive or inert. These organs are accommodated in a male thorax generally similar to average adult males.
This phantom contains a synthetic bone skeleton molded within a soft-tissue-equivalent material. The organs are located in an internal cavity with a separate torso cover that closes the phantom. Anterior sections of ribs and the sternum are molded into this cover.
Soft-tissue-equivalent blocks are used to position the organs and fill significant air spaces, providing continuity of the soft tissues throughout the phantom. The phantom is shipped assembled with inert organs. Any or all of these organs can be replaced with radioactive organs, which are shipped in separate packages.
