Intra‐ and inter‐fractional liver and lung tumor motions treated with SBRT under active breathing control
PURPOSE To assess intra- and inter-fractional motions of liver and lung tumors using active breathing control (ABC). METHODS AND MATERIALS Nineteen patients with liver cancer and 15 patients with lung cancer treated with stereotactic body radiotherapy (SBRT) were included in this retrospective study. All patients received a series of three CTs at simulation to test breath-hold reproducibility...
متن کاملAccuracy and inter-observer variability of 3D versus 4D cone-beam CT based image-guidance in SBRT for lung tumors
BACKGROUND To analyze the accuracy and inter-observer variability of image-guidance (IG) using 3D or 4D cone-beam CT (CBCT) technology in stereotactic body radiotherapy (SBRT) for lung tumors. MATERIALS AND METHODS Twenty-one consecutive patients treated with image-guided SBRT for primary and secondary lung tumors were basis for this study. A respiration correlated 4D-CT and planning contours...
متن کاملThe colossal circumvention of the lung lesion during lung stereotaxy
This is a case report on stereotaxic (Stereotactic Body Radiotherapy-SBRT) for lung cancer located in the left lower lobe (Segment 6, S6). There have been no reports on marked displacement of the peripheral lung cancer during radiotherapy. A pulmonary nodule was discovered on computed tomography (CT) conducted for a persistent cough in an 87-year-old male. According to diagnostic imaging, this ...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولAdaptive Stereotactic-body Radiation Therapy (SBRT) Planning for Lung Cancer Significance and Innovation: Tumor shrinkage during SBRT of lung cancer
Introduction: SBRT is an emerging radiotherapy technique for treating early-stage non-small cell lung cancers (NSCLC) or oligometastatic lesions to the lung [3, 4]. Significant tumor shrinkage has been observed in some patients during the course of SBRT [1, 2]. Adaptive planning has the potential to reduce radiation dose to organs of risk (OARs), and further escalate radiation dose to the tumor...
