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

PET is an important and growing imaging modality. PET instrumentation has undergone a
steady evolution improving various aspects of imaging. In this review, we discuss recent and …

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 …

A cone beam computed tomography (CBCT) scanner integrated with a linear accelerator is
a powerful tool for image guided radiotherapy. Respiratory motion, however, induces …

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

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 …

Purpose The purpose of this educational report is to provide an overview of the present state‐
of‐the‐art PET auto‐segmentation (PET‐AS) algorithms and their respective validation, with …

Respiratory motion can introduce significant errors in radiotherapy. Conventional CT scans
as commonly used for treatment planning can include severe motion artifacts that result from …

This paper describes a method for 4D imaging, which is used to study respiratory organ
motion, a key problem in various treatments. Whilst the commonly used imaging methods …

Respiratory motion degrades anatomic position reproducibility during imaging, necessitates
larger margins during radiotherapy planning and causes errors during radiation delivery …
