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 …

Purpose: To compile and review data on the topic of organ motion and its management.
Methods and Materials: Data were classified into three categories:(a) patient position-related …

Purpose: In this work, three-dimensional (3D) motion of lung tumors during radiotherapy in
real time was investigated. Understanding the behavior of tumor motion in lung tissue to …

Purpose: Geometric uncertainties in the process of radiation planning and delivery constrain
dose escalation and induce normal tissue complications. An imaging system has been …

PURPOSE: To review the dose limits and standardize the three-dimenional (3D)
radiographic definition for the organs at risk (OARs) for thoracic radiotherapy (RT), including …

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

A method is proposed that incorporates the effects of intratreatment organ motion due to
breathing on the dose calculations for the treatment of liver disease. Our method is based on …

Purpose: To relate lung dose-volume histogram-based factors to symptomatic radiation
pneumonitis (RP) in patients with lung cancer undergoing 3-dimensional (3D) radiotherapy …

PURPOSE: To review the state of the art in image-guided precision conformal radiotherapy
and to describe how helical tomotherapy compares with the image-guided practices being …

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 …
