The simultaneous advancement of technologies for the delivery of precisely targeted
radiation therapy and the paradigm shift to substantial hypofractionation have led to …

Image-guided radiotherapy (IGRT) has helped to dramatically reduce safety margins
compensating for positioning uncertainties in radiotherapy. A remaining issue posing …

Background and purpose In real-time lung tumor-tracking stereotactic body radiotherapy
(SBRT), tracking accuracy is related to radiotherapy efficacy. This study aimed to evaluate …

Recent developments in image-guided radiotherapy are ushering in a new era of
radiotherapy for lung cancer. Positron emission tomography/computed tomography …

Background and purpose The objective of this study was to compare the latest respiratory
motion-management strategies, namely the internal-target-volume (ITV) concept, the mid …

PURPOSE: To assess the accuracy of current stereotactic body radiation therapy (SBRT)
lung treatment planning methodologies on irregular breathing patterns, we have performed …

Purpose: The purpose of this work was to assess the magnitude of setup uncertainties and
respiratory-induced motion of lung tumors by monitoring the location of fiducials implanted in …

Due to respiration, many tumours in the thorax and abdomen may move as much as 3 cm
peak-to-peak during radiation treatment. To mitigate motion-induced irradiation of normal …

Respiratory motion considerably influences dose distribution, and thus clinical outcomes in
radiotherapy for lung cancer. Breath holding, breath coaching, respiratory gating with …

Background. The survival rates for patients with non-small cell lung cancer (NSCLC) may be
improved by dose escalation; however, margin reduction may be required in order to keep …
