Fabrication and Characterization of Beam Quality Phantom for External Beam Radiotherapy [PDF]

Iranian Journal of Medical Physics
Introduction: Radiation dose measurement plays a major role in Radiation Dosimetry. Effective dose delivery to the patient is ensured with the recommendation of some protocol called Quality assurance (QA). It is necessary to confirm that the beam that is

Half body irradiation (HBI) for bone metastases in the modern radiotherapy technique era – A systematic review

Clinical and Translational Radiation Oncology
Bone metastases (BMs) are the most common cause of cancer-related pain and radiation therapy plays a key role in treating pain caused by it. The half-body irradiation (HBI) is a modality that can be used to treat patients with multiple painful BMs.
