Dynamic MLC Tracking Using 4D Lung Tumor Motion Modelling and EPID Feedback
Background: Respiratory motion causes thoracic movement and reduces targeting accuracy in radiotherapy. Objective: This study proposes an approach to generate a model to track lung tumor motion by controlling dynamic multi-leaf collimators. Material and Methods: All slices which contained tumor were contoured in the 4D-CT images for...
متن کاملAbdominal and pancreatic motion correlation using 4D CT, 4D transponders, and a gating belt
The correlation between the pancreatic and external abdominal motion due to respiration was investigated on two patients. These studies utilized four dimensional computer tomography (4D CT), a four dimensional (4D) electromagnetic transponder system, and a gating belt system. One 4D CT study was performed during simulation to quantify the pancreatic motion using computer tomography images at ei...
متن کاملA quantitative investigation on lung tumor site on its motion tracking in radiotherapy with external surrogates
Introduction: In external beam radiotherapy each effort is done to deliver 3D dose distribution onto the tumor volume uniformly, while minimizing the dose to healthy organs at the same time. Radiation treatment of tumors located at thorax region such as lung and liver has a challenging issue during target localization since these tumors move mainly due to respiration. There are...
متن کاملRespiratory Motion Reduction in PET/CT Using Abdominal Compression for Lung Cancer Patients
PURPOSE Respiratory motion causes substantial artifacts in reconstructed PET images when using helical CT as the attenuation map in PET/CT imaging. In this study, we aimed to reduce the respiratory artifacts in PET/CT images of patients with lung tumors using an abdominal compression device. METHODS Twelve patients with lung cancer located in the middle or lower lobe of the lung were recruite...
متن کاملGeneration of a Mean Motion Model of the Lung Using 4D-CT Image Data
Modeling of respiratory motion gains in importance within the field of radiation therapy of lung cancer patients. Current modeling approaches are usually confined to intra-patient registration of 3D image data representing the individual patient’s anatomy at different breathing phases. We propose an approach to generate a mean motion model of the lung based on thoracic 4D CT data of different p...
