Radiotherapy (RT) aims to deliver a spatially conformal dose of radiation to tumours while
maximizing the dose sparing to healthy tissues. However, the internal patient anatomy is …

The problem of respiratory motion has proved a serious obstacle in developing techniques
to acquire images or guide interventions in abdominal and thoracic organs. Motion models …

Task Group 101 of the AAPM has prepared this report for medical physicists, clinicians, and
therapists in order to outline the best practice guidelines for the external‐beam radiation …

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 …

Purpose: In this work, three-dimensional (3D) motion of lung tumors during radiotherapy in
real time was investigated. Understanding the behavior of tumor motion in lung tissue to …

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

Particle beams like protons and heavier ions offer improved dose distributions compared
with photon (also called x-ray) beams and thus enable dose escalation within the tumor …

Radiographic image guidance has emerged as the new paradigm for patient positioning,
target localization, and external beam alignment in radiotherapy. Although widely varied in …

Charged particle beam radiotherapy requires dedicated measures to compensate for the
dosimetric influence of inter-and intra-fractional target motion. Independent of the delivery …

In the era of conformal therapy and intensity-modulated therapy, there is an increased desire
to raise tumor dose to facilitate improved survival and decrease normal tissue dose to …
