Intravascular ultrasound (IVUS) is a medical imaging system, which uses a specially designed catheter equipped with a small ultrasound probing device at its distal end. This system allows the ultrasound signal to visualize the blood vessels from the inside and is capable of imaging the diseased vessels, measuring the dimension and composition of the plaque.(More)
Intravascular ultrasound (IVUS) is a medical imaging system, which uses a specially designed catheter equipped with a small ultrasound probing device at the distal end of the catheter. This system allows the ultrasound technology in visualizing the blood vessels from the inside and is capable of imaging the diseased vessels, measuring length of the plaque,(More)
In medical study, retinal image processing plays a vital role in detecting the abnormalities of eye or ocular diseases like Glaucoma and diabetic retinopathy. Glaucoma is one of the two major causes of blindness worldwide, accounting for approximately 13% of visually impaired people. Glaucoma is physiologically described as the deterioration of optic nerve(More)
In this paper the qualitative behaviour of a delayed tri-trophic food chain model with Holling type II and modified Leslie-Gower functional responses is studied. Condition for existence and local stability of the interior equilibrium of the model are derived. Hopf bifurcation analysis is discussed by considering gestation time delay as bifurcation(More)
