The anatomy of cancer patients changes between radiation treatment planning and delivery
as well as over the course of radiotherapy. Adaptive radiotherapy (ART) aims to deliver …

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 …

Radiomics is the use of quantitative imaging features extracted from medical images to
characterize tumor pathology or heterogeneity. Features measured at pretreatment have …

The use of magnetic resonance imaging (MRI) in radiotherapy (RT) planning is rapidly
expanding. We review the wide range of image contrast mechanisms available to MRI and …

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 …

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 …

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

Several recent developments in linear accelerator–based radiation therapy (RT) such as fast
multileaf collimators, accelerated intensity modulation paradigms like volumeric modulated …

Purpose: Commercial CT‐based image‐guided radiotherapy (IGRT) systems allow
