Pulmonary fissure segmentation on CT
A pulmonary fissure is a boundary between the lobes in the lungs. Its segmentation is of clinical interest as it facilitates the assessment of lung disease on a lobar level. This paper describes a new approach for segmenting the major fissures in both lungs on thin-section computed tomography (CT). An image transformation called "ridge map" is proposed for enhancing the appearance of fissures o...
متن کاملAutomatic pulmonary fissure detection and lobe segmentation in CT chest images
BACKGROUND Multi-detector Computed Tomography has become an invaluable tool for the diagnosis of chronic respiratory diseases. Based on CT images, the automatic algorithm to detect the fissures and divide the lung into five lobes will help regionally quantify, amongst others, the lung density, texture, airway and, blood vessel structures, ventilation and perfusion. METHODS Sagittal adaptive f...
متن کاملSegmentation of Pulmonary Fissures on Diagnostic CT { Preliminary Experience
We describe a new approach to detect the ssures between the lobes of the lungs in computed tomography (CT) scans. We focus on the detection of the major ssures in diagnostic CT. Our approach is to rst nd a region containing the ssure and then extract the ssure within this region by analyzing local features. We developed a \marching-bar method" to segment the region containing the ssure. After t...

15 صفحه اولEnsemble registration: combining groupwise registration and segmentation
We investigate incorporating structural information from segmentation into a groupwise registration framework. Previous work by Petrovic et al., using MR brain images, showed that using tissue fractions to help construct an intensity reference image gives better results than just using intensity images alone. In their work, a Gaussian Mixture Model (GMM) was fitted to the 1D intensity histogram...
