In this paper, we present a new region based active contour algorithm for ultrasound image segmentation. An energy function based on a localized region-based active contour and shifted Rayleigh distribution is formulated. In our active contour framework, the target and background are represented as small local regions and the energy optimization is calculated at each point separately. The proposed...
Carotid artery disease occurs when the diameter of the carotid arteries is narrowed because of a buidup of fatty plaque and cholesterol along the inside walls of the arteries. Carotid arteries can develop atherosclerosis which is a chronic disease characterized by unusual thickening and hardening of the carotid artery walls. The intima-media thickness (IMT) is a reliable early indicator of this pathology...
Ultrasound image segmentation is a difficult task due to the low contrast, blurry and signal/noise ratio. Hence, in this paper, we propose a segmentation method for ultrasound image using the level set method. In particular, the level set method utilizes a new derived speed function to improve the segmentation performance. This speed function provides a general form that incorporates an alignment...
Atherosclerosis is a cardiovascular disease very widespread into population. It is characterized by a thickening of the arterial walls, which affects blood flow. The intima-media thickness (IMT) has emerged as a reliable early indicator of this pathology.
Knowledge about the status of the female reproductive system is important for fertility problems and age related family planning. The volume of these fertility requests in our emancipated society is steadily increasing. Transvaginal ultrasound imaging of the follicles in the ovary gives important information about the ovarian aging, i.e., number of follicles, size, position and response to hormonal...
Arteriosclerosis is one of the most extended diseases of the arterial walls which may lead to serious heart disease. The intima-medial thickness (IMT) of the carotid artery has emerged as an early and reliable indicator of arteriosclerosis. It is measured using ultrasound B-scan. The IMT is still measured visually by the doctor. To solve all the problems related to the manual procedure employed, a...
