Human anatomical models have been indispensable to radiation protection dosimetry using Monte Carlo calculations. Existing MIRD-based mathematical models are easy to compute and standardize, but they are simplified and crude compared to human anatomy. This article describes the development of an image-based whole-body model, called VIP-Man, using transversal color photographic images obtained f...

A t the SNMMI Annual Meeting on June 14th in San Diego, CA, Joseph A. O’Donoghue, PhD, of Memorial Sloan–Kettering Cancer Center (New York, NY), received the 2016 Loevinger–Berman Award for his contributions to understanding of the radiobiology of targeted radionuclide therapy. The Loevinger–Berman Award is given annually by the SNMMI Medical Internal Radiation Dose (MIRD) Committee in honor of...

To determine quantities for radiation protection against high-energy electrons, such as those from LINAC, the organ dose equivalents and equivalent doses for the human body were calculated using EGS-4 Monte Carlo simulation code and an MIRD-5 mathematical human phantom. Conversion factors for the incident fluence to the organ dose equivalent, to the effective dose and to the effective dose equi...

Abstract. The goal of this project is to determine the absorbed dose of radiation to a patient using 99mTc-MAA as a tracer for a lung scan using the MIRD formula accounting only for the radiation dose contributed by the target organ. The radiation dose for other organs to the target organ is considered negligible as the uptake of 99mTc-MAA from other organs is less than 1%. In addition to calcu...

Introduction: The use of ionizing radiation in diagnostic medicine is expanding, and considering the fact that the practical dosimeter in a precise way is almost impossible, the Monte Carlo computational methods help researchers, to have coming up the lowest cost and error of the distribution of doses in the patient's body.   Materials and Methods: In this st...
