Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.Abstract Background TG‐43 formalism dose calculation for brachytherapy with the homogeneous water‐based assumption is widely used, which can lead to dose inaccuracy in treatment planning. Purpose Extremity malignancies are also treated with high‐dose‐rate (HDR) 192Ir interstitial brachytherapy, a treatment site that has not been specifically ...

Dose modeling of superficial brachytherapy applicator geometries using multiple radioisotopes
Medical Physics, Volume 53, Issue 9, September 2026.Abstract Background Superficial brachytherapy enables localized dose delivery for superficial cutaneous lesions, but conventional applicators may be limited in treating extended, irregular, or curved surfaces. Geometric constraints, gaps or overlaps between adjacent applicators, and placement‐related uncertainties can reduce dose uniformity ...

MCNP variance reduction overview [PDF]
, 1985 The MCNP code is rich in variance reduction features. Standard variance reduction methods found in most Monte Carlo codes are available as well as a number of methods unique to MCNP. We discuss the variance reduction features presently in MCNP as well as
