Combining flat-panel imaging with internal BB markers for precise HDR brachytherapy source localization: A simulation study. [PDF]

Med Phys
Abstract Background High Dose Rate (HDR) brachytherapy delivers concentrated radiation to the tumor by placing a high‐dose‐rate radioactive source directly inside the target. However, the sharp dose falloff also increases susceptibility to errors and uncertainties.

A comparison of outcomes for patients with intermediate and high risk prostate cancer treated with low dose rate and high dose rate brachytherapy in combination with external beam radiotherapy

Clinical and Translational Radiation Oncology, 2020
Introduction: There is evidence to support use of external beam radiotherapy (EBRT) in combination with both low dose rate brachytherapy (LDR–EBRT) and high dose rate brachytherapy (HDR–EBRT) to treat intermediate and high risk prostate cancer.

A Brief Review of Low-Dose Rate (LDR) and High-Dose Rate (HDR) Brachytherapy Boost for High-Risk Prostate

Frontiers in Oncology, 2019
For patients with unfavorable or high-risk prostate cancer, dose escalated radiation therapy leads to improved progression free survival but attempts to deliver increased dose by external beam radiation therapy (EBRT) alone can be limited by late ...
