Abstract Objective. Recently, the ICRP developed the pregnant-female mesh-type reference computational phantoms to assess radiation doses to the fetus. To support the generation of reference internal fetal dose coefficients, a fetal specific absorbed fraction (SAF) dataset for photons, electrons, neutrons, and alpha …

BACKGROUND: Computed tomography (CT) is sometimes necessary during pregnancy to diagnose and treat urgent conditions, but accurate fetal dose estimation remains challenging. Prior studies often relied on uterus dose or simplified fetal models, limiting organ-specific assessment. PURPOSE: To develop NCICT3.0 by incorporating …

Recently, the International Commission on Radiological Protection (ICRP) released pediatric reference computational phantoms in ICRP Publication 143, but has not released pediatric dose coefficients (DCs) for idealized external exposures. This study produced a comprehensive dataset of photon DCs by conducting Monte Carlo …

Abstract Objective . Hematopoietic stem cells (HSCs) are the primary target cells for radiation-induced leukemia. In postnatal individuals, red bone marrow (RBM) is commonly used as a surrogate dosimetric target region for the HSCs. During fetal development, however, HSCs are distributed across …

The International Commission on Radiological Protection (ICRP) has adopted mesh-type reference computational phantoms (MRCPs) for the calculation of new reference dose coefficients following the forthcoming general recommendations. In the present study, the computational performance of adult and pediatric MRCPs was systematically evaluated …

BACKGROUND: Radiotherapy may be suggested for pregnant cancer patients when treatment cannot be delayed, with careful targeting to minimize fetal dose. Considering that a successful case for a pregnant patient treated with proton beam craniospinal irradiation (CSI) was reported, carbon therapy can …

The Mesh-type Reference Computational Phantoms (MRCPs) offer high-resolution anatomical representations based on tetrahedral meshes, enabling accurate modeling of detailed structures such as skin layers and organs. Although these phantoms can be used in Geant4-based simulations, GATE-commonly used in medical imaging and therapy-has …
