Background & Aims: Cardiac and vascular diseases are among the main reasons of mortality. Diagnosis of these diseases in the first stages can be very helpful for their treatments. One of the effects of atherosclerosis is the reduction of vessel wall vibrations. Echocardiography images cannot show these vibrations because of their lack of resolution. Materials & Methods: This study was condu...

International Journal of Vascular Surgery and Medicine is the field that deals with preventing, diagnosing treating vascular blood vessel related diseases. The goal journal to provide an Open access platform for researchers share their expert knowledge in basic, clinical applied studies medicine.
Background: Autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. Although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. The biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...
In human eye, the state of blood vessel is a crucial diagnostic factor. The segmentation from fundus image difficult due to spatial complexity, adjacency, overlapping and variability vessel. detection ophthalmic pathologies like hypertensive disorders, diabetic retinopathy cardiovascular diseases are remain challenging task wide-ranging distribution vessels. this paper, Stacked Autoencoder CNN ...

Retina located in the back of the eye contains useful information in the diagnosis of certain diseases. By locating a blood vessel’s width, color, reflectivity, tortuosity and abnormal branching, one can deduce the existence of these diseases. In order for this to be achieved, blood vessels first need to be extracted from its background in fundus image. In this paper we propose a new method to ...
Diabetic cerebrovascular diseases are defined as cerebral vascular diseases induced by diabetes with sugar, fat and a series of nutrient substance metabolic disorders, resulting in intracranial large and small vessel diseases. About 20%-40% patients with type 2 diabetes suffer from cerebral blood vessel diseases. Diabetic cerebrovascular diseases are the main causes of death in patients with di...
In this paper, we propose a retinal vascular network model, which is an automatic process of generating a graph representation (i.e., a tree) of the retinal blood vessels and includes vessel geometrical features. It maps the retinal blood vessels and can facilitate vascular features such as the vessel width, bifurcation angle, among others to predict or earlier diagnose cardiovascular and relat...
