A serial 4DCT study to quantify range variations in charged particle radiotherapy of thoracic cancers
Weekly serial 4DCT scans were acquired under free breathing conditions to assess water-equivalent path length (WEL) variations due to both intrafractional and interfractional changes in tissue thickness and density and to calculate proton dose distributions resulting from anatomical variations observed in serial 4DCT. A template of region of interests (ROIs) was defined on the anterior-posterio...
متن کاملMethods for single-lung ventilation in pediatric patients.
We reviewed published values for airway measurements in children (Table 1) (1,2). Data from the first study was derived by analyzing fresh autopsy specimens of intact tracheo-bronchial trees from 160 children between the ages of 6 mo and 16 yr (1). Thin cross-sections of the airways were made at various levels and photographed on color slides. By using a metric rule photographed with the specim...
متن کاملVentilation Series Similarity: A Study for Ventilation Calculation Using Deformable Image Registration and 4DCT to Avoid Motion Artifacts
The major problem with ventilation distribution calculations using DIR and 4DCT is the motion artifacts in 4DCT. Quite often not all phases would exhibit mushroom motion artifacts. If the ventilation series similarity is sufficiently robust, the ventilation distribution can be calculated using only the artifact-free phases. This study investigated the ventilation similarity among the data deriv...
متن کاملFunctional lung imaging in thoracic cancer radiotherapy.
BACKGROUND Lung cancer is the No. 1 cancer killer of both men and women in the United States. Radiotherapy is frequently employed as part of the treatment. However, radiation must traverse surrounding regions of normal lung, potentially inducing pulmonary toxicity. Because these patients frequently have underlying lung disease, a radiation-induced decrement in lung function could be highly morb...
متن کاملA complete 4DCT-ventilation functional avoidance virtual trial: Developing strategies for prospective clinical trials
INTRODUCTION 4DCT-ventilation is an exciting new imaging modality that uses 4DCT data to calculate lung-function maps. Because 4DCTs are acquired as standard of care for lung cancer patients undergoing radiotherapy, 4DCT-ventiltation provides functional information at no extra dosimetric or monetary cost to the patient. The development of clinical trials is underway to use 4DCT-ventilation imag...
