Intrafraction tumour motion is an issue that is of increased interest in the era of image-guided
radiotherapy. It is particularly relevant for non-small cell lung cancer, for which a number of …

Purpose: The effects of respiratory motion on the tumor dose can be divided into the gradient
and interplay effects. While the interplay effect is likely to average out over a large number of …

The objective of this study is to quantify the clinical accuracy of the Cyberknife Xsight Lung
Tracking System (XLTS) in our center and calculate the PTV margin of XLTS treated lung …

Convex probe endobronchial ultrasound (CP-EBUS) and stereotactic body radiotherapy
(SBRT) are valuable tools in the diagnosis, staging, and treatment of thoracic malignancies …

Purpose To quantify the intra-and interfractional variations between lung tumours and
implanted markers. Materials and methods Gold markers were implanted transbronchially …

Objective: This study aims to analyse lung tumour motion and to investigate the correlation
between the internal tumour motion acquired from four-dimensional computed tomography …

Purpose: To provide a comprehensive characterization of a novel respiratory surrogate that
uses optical surface imaging (OSI) for accurate tidal volume (TV) measurement, dynamic …

Purpose Calculating the adequate target margin for real‐time tumor tracking using the
Cyberknife system is a challenging issue since different sources of error exist. In this study …

The objectives of this study were to estimate global uncertainty for patients with thoracic
tumors treated in our center using the CyberKnife VSI after placement of fiducial markers …

The purpose of this study was to evaluate the stability of complex markers implanted into
lung tumors throughout a course of stereotactic body radiotherapy (SBRT). Fifteen patients …
