Browser-based tool for quantitative analysis of coronary microvasculature from angiography image sequences
Vessel Analyzer is a browser-based research tool for quantitative analysis of coronary microvasculature from angiography image sequences. It applies a Frangi vesselness filter (Frangi et al. 1998, Medical Image Computing) and runs entirely in the browser using Pyodide and scikit-image. The software was developed by Vasco Sequeira, for research use only and is not intended for clinical decision-making.
- Quantitative measurement of vessel area and vessel fraction from angiography images
- Frangi vesselness filtering for vessel enhancement and segmentation
- Adjustable vessel width (sigma) and minimum segment size
- ROI-based analysis with polygon drawing
- Manual paint and erase tools for correction of missed or incorrect vessel segments
- Sequence analysis for image stacks across the cardiac cycle
- Projection-based analysis (Mean, Median, Min, Max Vesselness, Std Dev)
- Batch export of measurements and analyzed images
Open the live GitHub Pages site, upload one or more angiography images, set the pixel size and filter parameters, and click Run to analyze the current image. Results can be saved to the log and exported as CSV or image files.
