Imaging techniques for measuring lung ventilation are essential tools to study lung tissue response to radiation therapy. Most of the existing CT and image registration based ventilation measurement methods use two extreme phases (end expiration and end inspiration) while ignoring the important ventilation variation within the respiratory cycle. In this paper, we present a new instantaneous ventilation...
Lung function depends on mechanical lung expansion and contraction during the respiratory cycle. Recently developed dynamic 4D CT imaging and 3D image registration can be used to analyze regional lung function, which are significant for lung disease diagnosis, treatment and lung ventilation change during radiation therapy. 4D CT images of the lung can be reconstructed at any respiratory phase point...
<?Pub Dtl?>EMPIRE10 (Evaluation of Methods for Pulmonary Image REgistration 2010) is a public platform for fair and meaningful comparison of registration algorithms which are applied to a database of intrapatient thoracic CT image pairs. Evaluation of nonrigid registration techniques is a nontrivial task. This is compounded by the fact that researchers typically test only on their own data,...
