The clinical use of surface imaging has increased dramatically, with demonstrated utility for
initial patient positioning, real‐time motion monitoring, and beam gating in a variety of …

Motion and uncertainty in radiotherapy is traditionally handled via margins. The clinical
target volume (CTV) is expanded to a larger planning target volume (PTV), which is …

Protons are an interesting modality for radiotherapy because of their well defined range and
favourable depth dose characteristics. On the other hand, these same characteristics lead to …

Expanding on the highly successful first edition, this second edition of Proton Therapy
Physics has been completely restructured and updated throughout, and includes several …

This document is the report of a task group of the AAPM and has been prepared primarily to
advise medical physicists involved in the external‐beam radiation therapy of patients with …

Clinical radiotherapy procedures aim at high accuracy. However, there are many error
sources that act during treatment preparation and execution that limit the accuracy. As a …

Background External beam radiation therapy (EBRT) is a standard definitive treatment
option for men with localized prostate cancer and confers long-term prostate cancer control …

Purpose: Geometric uncertainties in the process of radiation planning and delivery constrain
dose escalation and induce normal tissue complications. An imaging system has been …

Cancer therapy with accelerated charged particles is one of the most valuable biomedical
applications of nuclear physics. The technology has vastly evolved in the past 50 years, the …

Pencil-beam scanning (PBS) proton therapy (PT), particularly intensity modulated PT,
represents the latest advanced PT technology for treating cancers, including thoracic …
