Automated image processing has the potential to assist in the early detection of diabetes, by detecting changes in blood vessel patterns in the retina. This paper describes progress towards the development of an integrated automated analyser of the retinal blood vessels in the vicinity of the optic disc using digital colour retinal images. First the optic disc was detected using a combination o...

Long ridiculed for their racial hybridity, India’s Anglo-Indians—a mixed race people—were called ‘Dingos’ and instructed rudely to “Go to Australia” after India won her Independence from the British in 1947. Although their first port of escape from India was Great Britain, thousands of Anglo-Indians left the Indian subcontinent (India, Pakistan and Sri Lanka) in the second wave of migration, i....

the coronary slow flow phenomenon (csfp) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. although the relation between the csfp and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the csfp and the conduction system disorder. in this case report, we describe a patient with the csfp ...

conclusions in most cases, the conus artery can be visualized in cardiac ct. a description of the conus artery should be a part of the standard clinical coronary ct angiography description. objectives to examine whether it is possible to visualize the conus artery in multi-slice computed tomography (ct). patients and methods in 79 consecutive patients (aged 56 ± 12.9 years; 13 women), 64-slice ...

This paper proposes a method for the Retinal image analysis through efficient detection of exudates and recognizes the retina to be normal or abnormal. The contrast image is enhanced by curvelet transform. Hence, morphology operators are applied to the enhanced image in order to find the retinal image ridges. A simple thresholding method along with opening and closing operation indicates the re...

AIM To recognise automatically the main components of the fundus on digital colour images. METHODS The main features of a fundus retinal image were defined as the optic disc, fovea, and blood vessels. Methods are described for their automatic recognition and location. 112 retinal images were preprocessed via adaptive, local, contrast enhancement. The optic discs were located by identifying th...

In this paper, we present an automated method to segment blood vessels in fundus retinal images. The method could be used to support a non-intrusive diagnosis in modern ophthalmology for early detection of retinal diseases, treatment evaluation or clinical study. Our method combines the bias correction to correct the intensity inhomogeneity of the retinal image, and a matched filter to enhance ...

The recognition of wakes generated by dark vessels is a tremendous and interesting challenge in the field maritime surveillance Synthetic Aperture Radar (SAR) images. paper aims at assessing detection performance different scenarios processing Sentinel-1 SAR images along with ground truth data. Results confirm that Radon-based approach an effective technique for wake-based vessels, they lead to...

In this research, we constructed functions that are necessary for the operation simulation system which assists medical students to inhibit brain aneurysm from exploding. The system reported in this paper is “detection of blood vessels”, “detection of brain aneurysm” and “route planning to brain aneurysm”. Not only the detection method but also the method to reduce the miss detection is realize...

Duplex Doppler US may be useful for the detection of thyroid malignancies that show either anarchic winding or penetrating "sword like" neoangiogenic vessels. It may be helpful in selecting nodules that should undergo fine needle aspiration biopsy.
