Accurate airway centerline extraction based on topological thinning using graph-theoretic analysis.
The quantitative analysis of the airway tree is of critical importance in the CT-based diagnosis and treatment of popular pulmonary diseases. The extraction of airway centerline is a precursor to identify airway hierarchical structure, measure geometrical parameters, and guide visualized detection. Traditional methods suffer from extra branches and circles due to incomplete segmentation results...
متن کاملColon Centerline Calculation for CT Colonography using Optimised 3D Topological Thinning
CT colonography is an emerging technique for colorectal cancer screening. Using this technique virtual reality models of the human colon are generated from an abdominal CT study of a suitably prepared patient. Manual navigation through these models is a slow and tedious process. It is possible to automate navigation by calculating the centerline of the human colon. There are numerous well docum...
متن کاملDistance-Based Topological Indices and Double graph
Let $G$ be a connected graph, and let $D[G]$ denote the double graph of $G$. In this paper, we first derive closed-form formulas for different distance based topological indices for $D[G]$ in terms of that of $G$. Finally, as illustration examples, for several special kind of graphs, such as, the complete graph, the path, the cycle, etc., the explicit formulas for some distance based topologica...
متن کاملEXTRACTION-BASED TEXT SUMMARIZATION USING FUZZY ANALYSIS
Due to the explosive growth of the world-wide web, automatictext summarization has become an essential tool for web users. In this paperwe present a novel approach for creating text summaries. Using fuzzy logicand word-net, our model extracts the most relevant sentences from an originaldocument. The approach utilizes fuzzy measures and inference on theextracted textual information from the docu...
متن کاملGPU-Based Airway Segmentation and Centerline Extraction for Image Guided Bronchoscopy
Bronchoscopy is an important minimal-invasive procedure for both diagnosis and therapy of several lung disorders, including lung cancer. However, narrow airways and complex branching structure increases the difficulty of navigating to the target site inside the lungs. It is possible to improve navigation by extracting a map of the airways from CT images and tracking the tip of the bronchoscope....
