The efficacy of stereotactic body radiotherapy (SBRT) has been well demonstrated.
However, it presents unique challenges for accurate planning and delivery especially in the …

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 …

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 …

Introduction Stereotactic body radiation therapy (SBRT) uses advanced technology to
deliver a potent ablative dose to deep-seated tumors in the lung, liver, spine, pancreas …

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 …

The aim of this work was to quantify the ability to predict intrafraction diaphragm motion from
an external respiration signal during a course of radiotherapy. The data obtained included …

We present a technique for modeling liver motion during the respiratory cycle using intensity‐
based nonrigid registration of gated magnetic resonance (MR) images. Three‐dimensional …

Purpose: The correlation of the respiratory motion of external patient markers and abdominal
tumors was examined. Data of this type are important for image-guided therapy techniques …

Purpose: An accurate model of breathing motion under quiet respiration is desirable to
obtain the most accurate and conformal dose distributions for mobile lung cancer lesions …
