Radiation Oncology continues to rely on accurate delivery of radiation, in particular where
patients can benefit from more modulated and hypofractioned treatments that can deliver …

Purpose Endobronchial electromagnetic transponder beacons (EMT) provide real-time,
precise positional data of moving lung tumors. We report results of a phase 1/2, prospective …

Purpose To evaluate the efficacy of using bronchoscopically implanted anchored
electromagnetic transponders (EMTs) as surrogates for 1) tumor position and 2) repeatability …

放射治疗是乳腺癌综合治疗的有效手段之一, 但因受器官运动等诸多因素影响,
乳腺癌靶区发生偏移, 使放疗的精确度大大降低. 目前临床上主要通过各种运动监测技术来监测 …

Purpose. Radiation dose delivered to targets located near the upper-abdomen or in the
thorax are significantly affected by respiratory-motion. Relatively large-margins are …

Objective. To propose lung contour deformation features (LCDFs) as a surrogate to estimate
the thoracic internal target motion, and to report their performance by correlating with the …

In modern radiation therapy for lung cancer, examining the uncertainty between tumor
motion and beam delivery is vitally important. To lower the radiation dose delivery to the …

Purpose To develop a framework for robust optimization of real‐time respiratory motion
adaptive VMAT treatment plans, and to evaluate the robustness of resulting plans to …

Purpose Mobile lung tumors are increasingly being treated with ablative radiotherapy, for
which precise motion management is essential. In‐room stereoscopic radiography systems …

Abstract Hintergrund und Ziele: Atembewegte Tumore stellen die Strahlentherapie vor
besondere Herausforderungen. Die durch die Atmung hervorgerufene Bewegung reduziert …
