PHANTOM is a group of computational human phantom libraries created by the physicists at the National Cancer Institute in collaboration with external collaborators. PHANTOM libraries currently available are as follows. The cross mark means it is available for release.

File format	UF/NCI reference size phantoms	UF/NCI body size-dependent phantoms1	ICRP reference phantoms	UF/NCI pregnant women phantoms
Number of phantoms	12	362	12	8
Arms2	w and w/o	w and w/o	w and w/o	w and w/o
Binary voxel	x	x	Available from ICRP 110 and 143	x
DICOMRT3	x	x	x	x
MC input available	MCNP for w arms, GEANT4 for w/o arms

¹The phantom files of the body size-dependent phantom library, which are large in size, can be obtained upon request through external file transfer services.

²The phantoms with the arms removed may be used for medical radiation dose calculations where the arms may be raised.

³DICOMRT files are only available for the phantoms with the arms removed. DICOM-CT and DICOM-structure files are available, which can be directly imported into Treatment Planning System (TPS). Recommended citation for DICOMRT files: Griffin 2019

#mastertable_ref_XXXXXXXX.xlsx file contains the information required for Monte Carlo radiation transport contained in the following tabs:

• summary_arm: data for the UF/NCI phantoms with the arms attached, voxel tag, organ names, material card # corresponding to the material data in material tab
• summary_noarm: data for the UF/NCI phantoms with the arms removed, voxel tag, organ names, material card # corresponding to the material data in material tab
• material: material #, material type, elemental composition and fraction
• dose response function: photon dose response function (absorbed dose per photon fluence) for active marrow and endosteum
• marrow_fraction: the fraction of active marrow and endosteum in different bone sites

• Detailed organ models: heart, brain
• Implementation of lymphatic nodes into the body size-dependent library
