Stereotactic Body Radiotherapy for Lung Lesions using Multiple Phase 3D-CT Based on the Analysis of Radiobiological Parameters
Introduction: Planning target volume (PTV) is generated from internal treatment volume (ITV) using four-dimensional computed tomography (4D-CT) for enhanced therapeutic gain in the stereotactic body radiotherapy for lung lesions (SBRT-Lung). This study aimed to propose a strategy to generate ITV on multiple-phase 3D-CT and enhance therapeutic gain in SBRT-Lung. <stron...
متن کاملStereotactic ablative radiotherapy for lung cancer
Stereotactic ablative radiotherapy (SABR), which is also referred to as stereotactic body radiotherapy (SBRT), is defined as “the precise irradiation of an image defined extra-cranial lesion associated with the use of high radiation dose in a small number of fractions”. SABR is a relatively recent advance in the treatment of small peripheral non-small cell lung tumours. The concept of SABR was ...
متن کاملStereotactic ablative body radiotherapy for lung cancer.
Lung stereotactic ablative radiotherapy (SABR) is a method of delivering high 'ablative' doses of radiotherapy to tumours in the lung. It was developed at the Karolinska Institute in the early 1990s using the methods established in cranial radiosurgery with multiple beams prescribed to an isodose and using a custom designed stereotactic body frame for immobilisation. Since then, aligned with th...
متن کاملQuantification of interplay and gradient effects for lung stereotactic ablative radiotherapy (SABR) treatments
This study quantified the interplay and gradient effects on GTV dose coverage for 3D CRT, dMLC IMRT, and VMAT SABR treatments for target amplitudes of 5-30 mm using 3DVH v3.1 software incorporating 4D Respiratory MotionSim (4D RMS) module. For clinically relevant motion periods (5 s), the interplay effect was small, with deviations in the minimum dose covering the target volume (D99%) of less t...
متن کاملInvestigation of lung normal tissue doses in lung tumors radiation therapy using both gated and conventional radiotherapy
Introduction: In radiation therapy of lung tumors, respiratory motion causes target moving, so a larger margin is needed to cover the clinical target volume (CTV). With the margin increasing, a larger volume of normal tissue will be exposed to high-dose. In this study, dosimetric parameters of normal lung tissue were compared between gated and conventional radiotherapy (RT), u...
