Evaluation of relative biological effectiveness of 225Ac and its decay daughters with Monte Carlo track structure simulations

EJNMMI Physics
Background 225Ac is a radionuclide that can be utilized in targeted alpha therapy (TAT). To accurately assess the absorbed dose and radiation effects in TAT, it is necessary to calculate the relative biological effectiveness (RBE).

Relative Biological Effectiveness of Antiprotons the AD-4/ACE Experiment

, 2017
Particle beam cancer therapy was introduced by Robert R. Wilson in 1947 based on the advantageous depth dose profile of a particle beam in human-like targets (water) compared to X-rays or electrons.

Variations in linear energy transfer distributions within a European proton therapy planning comparison of paediatric posterior fossa tumours

Physics and Imaging in Radiation Oncology
Background and Purpose: Radiotherapy for paediatric posterior fossa tumours may cause complications in the brainstem and upper spinal cord due to high doses. With proton therapy (PT) this risk may increase due to higher relative biological effectiveness (

Dosimetric comparison of intensity-modulated proton therapy and proton arc therapy for pediatric ependymoma

Acta Oncologica
Background and purpose: Proton Arc Therapy (PAT) is an emerging proton therapy treatment modality with the potential to reduce radiation exposure to healthy tissues compared to conventional Intensity-Modulated Proton Therapy (IMPT) with fewer beams. This
