Vascular network segmentation: an unsupervised approach [PDF]
, 2012 Micro-tomography produces high resolution images of biological structures such as vascular networks. In this paper, we present a new approach for segmenting vascular network into pathological and normal regions from considering their micro-vessel 3D ...

3D simulations of gas puff effects on edge plasma and ICRF coupling in JET [PDF]
, 2017 Recent JET (ITER-Like Wall) experiments have shown that the fueling gas puffed from different locations of the vessel can result in different scrape-off layer (SOL) density profiles and therefore different radio frequency (RF) coupling.

Peripapillary Vessel Density as Early Biomarker in Multiple Sclerosis [PDF]
Frontiers in Neurology, 2020 Background: To evaluate retinal vessel density (VD) in macular and in peripapillary regions in patients with recent onset of multiple sclerosis, at initial demyelinating event (IDE) and in matched relapsing-remitting multiple sclerosis (RRMS) patients. Methods: We evaluated VD in superficial capillary plexus, deep capillary plexus, choriocapillaris and

Awake chronic mouse model of targeted pial vessel occlusion via photothrombosis [PDF]
, 2020 Animal models of stroke are used extensively to study the mechanisms involved in the acute and chronic phases of recovery following stroke. A translatable animal model that closely mimics the mechanisms of a human stroke is essential in understanding ...

3D Retinal Vessel Density Mapping With OCT-Angiography
IEEE Journal of Biomedical and Health Informatics, 2020 Optical Coherence Tomography Angiography (OCTA) is a novel, non-invasive imaging modality of retinal capillaries at micron resolution. Recent studies have correlated macular OCTA vascular measures with retinal disease severity and supported their use as a diagnostic tool.
