Segmenting Retinal Vessels Using a Shallow Segmentation Network to Aid Ophthalmic Analysis
Mathematics, 2022 Retinal blood vessels possess a complex structure in the retina and are considered an important biomarker for several retinal diseases. Ophthalmic diseases result in specific changes in the retinal vasculature; for example, diabetic retinopathy causes ...

Discerning calvarian microvascular networks by combined optoacoustic ultrasound microscopy
Photoacoustics, 2020 Bone microvasculature plays a paramount role in bone marrow maintenance, development, and hematopoiesis. Studies of calvarian vascular patterns within living mammalian skull with the available intravital microscopy techniques are limited to small scale ...

Retinal blood vessel analysis using optical coherence tomography in multiple sclerosis
Veins and Lymphatics, 2022 Background: Both greater retinal neurodegenerative pathology and greater cardiovascular burden have been seen in persons with multiple sclerosis (pwMS).1,2 Moreover, studies have described multiple extracranial and intracranial vasculature changes in ...

Simultaneous segmentation and anatomical labeling of the cerebral vasculature [PDF]
Medical Image Analysis, 2014 We present a novel algorithm for the simultaneous segmentation and anatomical labeling of the cerebral vasculature. Unlike existing approaches that first attempt to obtain a good segmentation and then perform labeling, we optimize for both by simultaneously taking into account the image evidence and the prior knowledge about the geometry and ...

Quantification of vascular networks in photoacoustic mesoscopy
Photoacoustics, 2022 Mesoscopic photoacoustic imaging (PAI) enables non-invasive visualisation of tumour vasculature. The visual or semi-quantitative 2D measurements typically applied to mesoscopic PAI data fail to capture the 3D vessel network complexity and lack robust ...

Segmentation and Automatic Identification of Vasculature in Coronary Angiograms
Computational and Mathematical Methods in Medicine, 2021 Coronary angiography is the “gold standard” for the diagnosis of coronary heart disease, of which vessel segmentation and identification technologies are paid much attention to. However, because of the characteristics of coronary angiograms, such as the complex and variable morphology of coronary artery structure and the noise caused by various factors,

Enhancing Retinal Blood Vessel Segmentation through Self-Supervised Pre-Training
Proceedings, 2020 The segmentation of the retinal vasculature is fundamental in the study of many diseases. However, its manual completion is problematic, which motivates the research on automatic methods.
