The limited ability to control for a tumour's location compromises the accuracy with which
radiation can be delivered to tumour-bearing tissue. The resultant requirement for larger …

PURPOSE: The purpose of this study was to quantify the effects of four-dimensional
computed tomography (4DCT), 4D image guidance (4D-IG), and beam gating on calculated …

Organ motion as a result of respiratory and cardiac motion poses significant challenges for
the accurate delivery of radiotherapy to both the thorax and the upper abdomen. Modern …

Stereotactic body radiotherapy (SBRT) has emerged as the standard treatment for medically
inoperable early-staged non-small cell lung cancer (NSCLC). The local control rate after …

PURPOSE: To assess the benefit derived from the reduction of planning target volumes
(PTVs) afforded by tumor motion management in treatment planning for lung cancer …

Primary and metastatic tumors to the lung have been principle targets for the noninvasive
high-doseper-fraction treatment programs now officially called stereotactic body radiation …

Purpose Stereotactic body radiation therapy (SBRT) for early-stage inoperable non-small
cell lung cancer (NSCLC) patients delivers high doses that require high-precision treatment …

PURPOSE: To evaluate the potential of image-guidance, gating and real-time tumor tracking
to improve accuracy in pulmonary stereotactic body radiotherapy (SBRT). MATERIALS AND …

PURPOSE: To assess intrafractional geometric accuracy of lung stereotactic body radiation
therapy (SBRT) patients treated with volumetric image guidance. METHODS AND …

The challenges of lung cancer radiotherapy are intra/inter‐fraction tumor/organ
anatomy/motion changes and the need to spare surrounding critical structures. Evolving …
