Recent changes across NCI Dose Tools.
NCICT4 — View changes
Added scanner-specific radial dose correction that uses CTDIc and CTDIp to approximate bowtie-filter shape and correct reference-scanner organ doses while preserving CTDIvol.
PHANTOM — View changes
Released individually downloadable DICOM CT and RT Structure Set packages for all 362 NCI body size-dependent armless phantoms at both high and low resolution.
NCINM4 — View changes
Expanded the ICRP-mesh S-value library with 182 directly alpha-emitting radionuclides from ICRP Publication 107 for all 12 age- and sex-specific mesh phantoms.
NCIRF4 — View changes
Introduced an integrated custom x-ray spectrum generator powered by SpekPy 2.5.4 through the NCI-hosted SpekPy service.
NCICT
NCICT estimates organ absorbed dose and effective dose for pediatric, adult, and pregnant patients undergoing computed tomography examinations.
NCIRF
NCIRF provides geometry-aware Monte Carlo organ and skin dose estimation for radiography and fluoroscopy research workflows.
NCINM
NCINM supports radionuclide and radiopharmaceutical absorbed-dose estimation for pediatric, adult, and pregnancy-oriented nuclear medicine research.
PHANTOM
The NCI computational human phantom libraries provide reference, size-dependent, pediatric, adult, and pregnant anatomical models for radiation dosimetry research.
