GAN-Based Approach for Diabetic Retinopathy Retinal Vasculature Segmentation [PDF]

Bioengineering, 2023
Most diabetes patients develop a condition known as diabetic retinopathy after having diabetes for a prolonged period. Due to this ailment, damaged blood vessels may occur behind the retina, which can even progress to a stage of losing vision.

In Vivo Quantitative Vasculature Segmentation and Assessment for Photodynamic Therapy Process Monitoring Using Photoacoustic Microscopy [PDF]

Sensors, 2021
Vascular damage is one of the therapeutic mechanisms of photodynamic therapy (PDT). In particular, short-term PDT treatments can effectively destroy malignant lesions while minimizing damage to nonmalignant tissue.

Enhancement and Segmentation Workflow for the Developing Zebrafish Vasculature [PDF]

Journal of Imaging, 2019
Zebrafish have become an established in vivo vertebrate model to study cardiovascular development and disease. However, most published studies of the zebrafish vascular architecture rely on subjective visual assessment, rather than objective ...

3D vasculature segmentation using localized hybrid level-set method. [PDF]

Biomed Eng Online, 2014
Intensity inhomogeneity occurs in many medical images, especially in vessel images. Overcoming the difficulty due to image inhomogeneity is crucial for the segmentation of vessel image.This paper proposes a localized hybrid level-set method for the segmentation of 3D vessel image.

CT-derived vessel segmentation for analysis of post-radiation therapy changes in vasculature and perfusion

Frontiers in Physiology, 2022
Vessel segmentation in the lung is an ongoing challenge. While many methods have been able to successfully identify vessels in normal, healthy, lungs, these methods struggle in the presence of abnormalities.

Segmental Responses of Dog Paw Vasculature [PDF]

Circulation Research, 1968
The production of constrictive responses limited to either arterial or venous segments of the vasculature of the dog paw was tested by stimulating various peripheral nerves of the hind leg. Resistance changes of the total vasculature of the paw, and of three of its component series-coupled segments (arterial, small vessel, and venous) were studied ...
