New AI methods improve brain and eye blood vessel segmentation

Researchers have developed new methods for segmenting small blood vessels in the brain using ultra-high resolution 7T MRI scans. The SMILE-UHURA challenge provided a dataset and platform for developing machine learning algorithms, with submitted deep learning methods achieving reliable segmentation performance, reaching Dice scores up to 0.838. Separately, a new local-sensitive connectivity filter (LS-CF) was proposed to improve existing vessel segmentation techniques like the Frangi filter, showing competitive results across various multimodal datasets and outperforming state-of-the-art approaches on specific datasets.

    Local-sensitive connectivity filter (ls-cf): A post-processing unsupervised improvement of the frangi, hessian and vesselness filters for multimodal vessel segmentation

    A retinal vessel analysis is a procedure that can be used as an assessment of risks to the eye. This work proposes an unsupervised multimodal approach that improves the response of the Frangi filter, enabling automatic vessel segmentation. We propose a filter that computes pixel-…
