Mechanical analysis of lung CT images using nonrigid registration
Image registration plays an important role in pulmonary image analysis. Accurate image registration is a challenging problem when the lungs have deformation with large distance. Registration results estimate the local tissue movement and are useful for studying lung mechanical quantities. In this thesis, we propose a new registration algorithm and a registration scheme to solve lung CT matching...
متن کاملNonrigid Registration of Lung CT Images Based on Tissue Features
Nonrigid image registration is a prerequisite for various medical image process and analysis applications. Much effort has been devoted to thoracic image registration due to breathing motion. Recently, scale-invariant feature transform (SIFT) has been used in medical image registration and obtained promising results. However, SIFT is apt to detect blob features. Blobs key points are generally d...
متن کاملRegularized Nonrigid Registration of Lung CT Images by Preserving Tissue Volume and Vesselness Measure
Image registration is an important research area within pulmonary image analysis. Accurate registration is critical to post-analysis of lung mechanical properties and useful for clinical applications. To improve registration accuracy, we design a nonrigid registration algorithm to preserve both parenchymal tissue volume and vesselness measure. In addition, the transformation is regularized usin...
متن کاملMass preserving image registration for lung CT
This paper presents a mass preserving image registration algorithm for lung CT images. To account for the local change in lung tissue intensity during the breathing cycle, a tissue appearance model based on the principle of preservation of total lung mass is proposed. This model is incorporated into a standard image registration framework with a composition of a global affine and several free-f...
متن کاملB-spline Nonrigid Grid Registration of Medical Images Using Free-Form Deformations
Image registration is an important tool to deal with various problems in medical imaging. It has many potential applications in clinical diagnosis. It is a process of aligning two images into a common coordinate system in order to monitor subtle changes between the two. In the medical imaging field, fast deformable registration methods are needed especially in intra-operative settings character...
