Predicting respiratory motion for four-dimensional radiotherapy.
Adapting radiation delivery to respiratory motion is made possible through corrective action based on real-time feedback of target position during respiration. The advantage of this approach lies with its ability to allow tighter margins around the target while simultaneously following its motion. A significant hurdle to the successful implementation of real-time target-tracking-based radiation...
متن کاملEffect of audio instruction on tracking errors using a four‐dimensional image‐guided radiotherapy system
The Vero4DRT (MHI-TM2000) is capable of performing X-ray image-based tracking (X-ray Tracking) that directly tracks the target or fiducial markers under continuous kV X-ray imaging. Previously, we have shown that irregular respiratory patterns increased X-ray Tracking errors. Thus, we assumed that audio instruction, which generally improves the periodicity of respiration, should reduce tracking...
متن کاملFour-dimensional radiotherapy planning for DMLC-based respiratory motion tracking.
Four-dimensional (4D) radiotherapy is the explicit inclusion of the temporal changes in anatomy during the imaging, planning, and delivery of radiotherapy. Temporal anatomic changes can occur for many reasons, though the focus of the current investigation is respiration motion for lung tumors. The aim of this study was to develop 4D radiotherapy treatment-planning methodology for DMLC-based res...
متن کاملDesign and Fabrication of a Four-Dimensional Respiratory Phantom for Studying Tumor Movement in Radiotherapy with Magnetic Resonance Imaging
Introduction: In radiation therapy, determining the location of the tumor accurately during irradiation is one of the most important requirements. However, lung tumors are not fixed in a single location and move during irradiation due to respiratory motion. Due to limitations in assessing such movements, using a lung phantom can be useful and operational for their fast, easy an...
متن کاملTechnical Controversy in International Standardization
The development of larger technical systems relies on the coordination of autonomous action of a multitude of individuals and organizations. Institutional settings, often neglected in the analysis of technical development, help to achieve such coordination. Our analysis of international technical standardization in telecommunications highlights an institutionalized process aiming at the creatio...
