Purpose Current clinical brachytherapy dose calculations are typically based on the
Association of American Physicists in Medicine Task Group report 43 (TG-43) guidelines …

This paper shows an analytical, numerical and experimental investigation to comprehend
the role of grained inhomogeneity which plays in micro flexible rolling in terms of the …

The aim of this study is to evaluate organ-at-risk (OAR) doses obtained from different
designs of intracavitary cylinder applicators during high-dose-rate (HDR) brachytherapy of …

Background Tetrahedral-mesh geometries can be used in the MCNP code, but the MCNP
code accepts only the geometry in the Abaqus input file format; hence, the existing …

This chapter discusses the clinical dose calculation methods for patient-specific treatment
planning. Generally, TG-43 dose calculation limitations can be attributed to five phenomena …

Voxel-level absorbed dose (VLAD) is rarely calculated for nuclear medicine (NM)
procedures involving unsealed sources or 90Y microspheres (YM). The current standard of …

Brachytherapy uses radiation sources in contact with the tumor to eliminate it whilst
preserving healthy tissues. This technique has been under continuous development for …

The use of tetrahedral-based phantoms in conjunction with Monte Carlo dose calculation
techniques has shown high capabilities in radiation therapy. However, the generation of a …
