Purpose: Several isotopes are available for low dose‐ratebrachytherapy of the prostate. Currently, most implants use a single isotope. However, the use of dual‐isotope implants may yield an advantageous combination of characteristics such as half

Purpose: Low dose-rate brachytherapy is commonly used to treat prostate cancer. However, once implanted, the seeds are vulnerable to loss and movement. The goal of this work is to investigate the dosimetric and radiobiological effects of the types of

Purpose: Accurate prostate low dose-rate brachytherapy treatment plan evaluation is important for future care decisions. Presently, an evaluation is based on dosimetric quantifiers for the tumor and organs at risk. However, these do not account for e
