TOPAS-microdosimetry
TOPAS-microdosimetry is an extension to the TOPAS toolkit that provides settings for common microdosimeters, scoring of lineal energy (y/dy) and a biological weight function based on microdosimetric properties.
The extension can be downloaded from here.
The extension is described in:

TOPAS
TOPAS is a user-friendly simulation software layered upon the general-purpose Geant4 particle transport toolkit. It was designed specifically for medical physics applications by MGH, Stanford and UCSF.
Plastimatch
Plastimatch is an open source software for image computation. Our main focus is high-performance volumetric registration of medical images, such as X-ray computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET).

TOPAS-RBE
TOPAS-RBE is an extension to the TOPAS toolkit that provides the ability to score relative biological effectiveness (RBE) of proton therapy. We provide scorers for several different RBE models from the scientific literature, to enable easy comparison of results.
The extension can be downloaded from here and documentation can be found here.
TOPAS-nBio
TOPAS-nBio is an extension to the TOPAS toolkit that is being developed as part of an ongoing NCI-R01. The goal is to follow the approach of the TOPAS software package, making Monte Carlo simulations easy-to-use with focus on radiation biology at sub-cellular scales.
