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 …

In this review article, we discuss various technical aspects of image-guided respiration-
gated radiation therapy. We first review some basic concepts related to respiratory gating …

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 …

From background physics and biological models to the latest imaging and treatment
modalities, the Handbook of Radiotherapy Physics: Theory and Practice covers all …

The success of highly target-conformal treatments such as intensity-modulated radiotherapy
(IMRT) can be compromised by motion of the inner organs and random patient setup errors …

Image guidance in radiotherapy and extracranial radiosurgery offers the potential for precise
radiation dose delivery to a moving tumour. Recent work has demonstrated how to locate …

PURPOSE: To assess the correlation of respiratory volume and abdominal displacement
with tumor motion as seen with X-ray fluoroscopy. Measurements throughout the patient's …

In an ideal radiotherapy procedure, the treatment system would continuously adapt the
radiation beam delivery to changes in the tumor position. The development of such a …

Respiration-induced tumour motion can potentially compromise the use of intensity-
modulated radiotherapy (IMRT) as a dose escalation tool for lung tumour treatment. We …

Traditional radiation treatment techniques, including threedimensional conformal radiation
therapy (3DCRT), do not provide a method for sparing critical structures that push into and …
