PHANTOM: Library of Computational Human Phantoms

Family of reference-size computational human phantoms

PHANTOM is a computational human phantom library that provides a shared anatomical foundation for NCI Dose Tools and related radiation dosimetry research. Computational phantoms are three-dimensional representations of human anatomy used to estimate organ doses in medical radiation procedures, radiation protection, and epidemiologic studies. The models were developed from patient CT-based anatomical segmentation and modified to match reference anatomical and anthropometric data, producing realistic but standardized phantoms for organ-level dosimetry.

The body size-dependent phantom library includes pediatric and adult models that represent both reference anatomy and a broad range of height and weight combinations. By selecting a phantom that more closely matches a patient or study population, NCI Dose Tools and related research applications can support more consistent organ dose assessment across different modalities and body habitus groups.

Resource Overview

  • Provides anatomically detailed computational human phantoms for radiation dosimetry research.
  • Supports pediatric and adult dose assessment using reference and size-dependent anatomy.
  • Serves as a foundational data resource for NCICT, NCINM, NCIRF, and related dosimetry studies.
