O método de Monte Carlo tem se tornado, ao longo dos anos, uma ferramenta padrão para
cálculos de dose absorvida e outras grandezas de interesse nas áreas de terapêutica e …

This study was intended to verify the capability of the Monte Carlo MCNP-4B code to evaluate
spatial dose distribution based on information gathered from CT or SPECT. Methods: A …

A new approach for calculating internal dose estimates was developed through the use of a
more realistic computational model of the human body. The present technique shows the …

Purpose: Radiopharmaceutical applications in nuclear medicine require a detailed dosimetry
estimate of the radiation energy delivered to the human tissues. Over the past years, …

Purpose Brachytherapy dose calculation is commonly performed using the Task Group-No
43 Report-Updated protocol (TG-43U1) formalism. Recently, a more accurate approach has …

The present work proposes a new mathematical eye model for ophthalmic brachytherapy
dosimetry. This new model includes detailed description of internal structures that were not …

Purpose: The dose delivered with a HDR 192 Ir afterloader can be separated into a dwell
component, and a transit component resulting from the source movement. The transit …

Dose calculation in high dose rate brachytherapy with 192 Ir is usually based on the TG-43U1
protocol where all media are considered to be water. Several dose calculation algorithms …

MATERIALS AND METHODS On the basis of anatomic descriptions (9) and information
published by Cristy and Eckerman (7), a revision to the mathemati cal model of the ORNL adult …

Targeted radionuclide therapy (TRT) and beta-emitting seeds brachytherapy (BSBT) exploit
the characteristics of energy deposited by beta-emitting radionuclides. Monte Carlo (MC) …
