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.
Distribution of height and weight of the size-dependent phantom library
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.
