High-energy beams of charged nuclear particles (protons and heavier ions) offer significant
advantages for the treatment of deep-seated local tumors in comparison to conventional …

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

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 …

In this work a novel plan optimization platform is presented where treatment is delivered
efficiently and accurately in a single dynamically modulated arc. Improvements in patient …

Intensity‐modulated radiation therapy (IMRT) represents one of the most significant
technical advances in radiation therapy since the advent of the medical linear accelerator. It …

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

Abstract Four-dimensional (4D) methods strive to achieve highly conformal radiotherapy,
particularly for lung and breast tumours, in the presence of respiratory-induced motion of …

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

We propose a new scanning protocol for generating 4D‐CT image data sets influenced by
respiratory motion. A cine scanning protocol is used during data acquisition, and two …

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 …
