The accurate analysis of Coronary angiographic images plays an important role in diagnosing arterial diseases. All angiograms suffer from varying background, consisting of heart tissues, which harden accurate detection of vessels. Therefore removing background is one of the important steps which have essential effect on improving performance of subsequent steps of vessel detection algorithm, es...

This paper deals with computed tomography angiography based vessel exploration. Large image sequences of the lower extremities are investigated in a clinical environment. Two different approaches for peripheral vessel diagnosis dealing with stenosis and calcification detection are introduced. The paper presents an automated vessel-tracking tool for curved planar reformation. A user interactive ...

BACKGROUND Detection of vascular invasion by hematoxylin and eosin staining is the current pathological assessment practice to diagnose breast carcinoma. However, conventional hematoxylin and eosin staining failed to distinguish between blood vessel invasion and lymphatic vessel invasion. Both are important prognostic criteria however with different outcomes. The aim of this study is to disting...

in this paper, a novel matched filter based on a new kernel function with cauchy distribution is introduced to improve the accuracy ofthe automatic retinal vessel detection compared with other available matched filter‑based methods, most notably, the methods builton gaussian distribution function. several experiments are conducted to pick the best values of the parameters for the new designedfi...

localizing the optic disc (od) in retinal fundus images is of critical importance, since it is very similar to hard exudates (found in pathology) in color and brightness. because of the importance of od localization in clinical applications, many techniques have been developed. in this paper, we present the results obtained from two methods, correlation and least square, to approximate the opti...

Vasculitis create a local inflammatory process in the vessel wall, which determines the different organic manifestations according to vessel size and location. Imaging techniques play a key role in the characterization and detection of large and medium size vessel vasculitis. Imaging is able to detect the vessel wall edema and to monitor the therapeutic response. In small vessel vasculitis, ima...

Vasculitides create a local inflammatory process in the vessel wall, which determines the different organic manifestations according to vessel size and location. Imaging techniques play a key role in the characterization and detection of large and medium size vessel vasculitides. Imaging is able to detect the vessel wall edema and to monitor the therapeutic response. In small vessel vasculitis,...

Diabetes is a metabolic disease which damage blood vessel. Damage in retinal blood vessel of the human eye due to effect of diabetes is termed as Diabetic Retinopathy (DR). This abnormality in the blood vessel will cause a leakage of blood from the vessel and forms a red dot. This is named as Microaneurysm. Microaneurysm in the retina causes a swelling of retinal tissue which in turn causes clo...
