Thus, the fully automated proposed system proved to be an efficient method for watermarking the atherosclerotic ultrasound video for stroke application. Cardiovascular and Cancer, the most common life-threatening diseases in western countries, are two of the most important topics focused in the book. There have been many methods that report estimation or classification of vigilance decrement. Results: The coefficient of correlation was 0. Both algorithms are modeled as a two stage process. However, Ultrasound images present poor quality, very low signal to noise ratio and a lot of artifacts.

There are several daily real life applications that require relatively high level of vigilance. Conclusions: Our automated measurement system gave satisfying results in comparison with manual measurements. Furthermore, multimodality imaging is needed for validation of such advanced methods for stroke and cardiovascular risk stratification. The results demonstrate that the proposed method has a better performance in both speckle reduction and preservation of structural features. In fact, Ultrasound application range is vast, covering almost all organs of the human body, including the brain where Tran-cranial Doppler Ultrasound is very important to assess the brain vasculature. Its low cost, when compared with other medical image modalities, makes it one of the preferred tools for medical monitoring, follow-up and diagnosis. Some chapters are direct contributions from medical research groups where Ultrasound has also received great attention in the last decade.

Of the mainstream ablative procedures reported in the literature, the cryotherapy data appear to be the most durable. However, Ultrasound images present poor quality, very low signal to noise ratio and a lot of artifacts. In the paper we perform comparison of these techniques both for computer generated signals and ultrasound images. This technology is very appealing for medical applications because it is non-ionizing, non-invasive and it is available in most of the medical and clinical facilities. Some subbands involving an approximation subband and detail subbands are revealed in output. However, Ultrasound images present poor quality, very low signal to noise ratio and a lot of artifacts.

Then, we perform a discrete wavelet transform on the coefficients obtained from total variation. The experiments on phantom images and real 2D ultrasound datasets show that the proposed method outperforms other related well-accepted methods, both in terms of objective and subjective evaluations. More advanced methods need to be developed which can segment the carotid artery walls into multiple regions such as the bulb region and areas both proximal and distal to the bulb. The E-mail message field is required. The performance of the algorithm has been tested using quantitative measures on synthetic and real ultrasound images. In fact, Ultrasound application range is vast, covering almost all organs of the human body, including the brain where Tran-cranial Doppler Ultrasound is very important to assess the brain vasculature. The difficulties are being overcome and novel and advanced methods are being proposed for detection, characterization and segmentation of abnormalities in several organs.

Fracture healing goes through three distinct stages: reactive phase which includes inflammatory phase and granulation tissue formation, reparation phase which includes callus formation and lamellar bone deposition, and remodeling phase in which woven bone is replaced by mature bone. By this, new techniques based on Ultrasound were introduced in the clinical practice for diagnosis and therapeutics, mainly in hospital facilities. Hence, vigilance decrement can lead to serious consequences such as traffic accidents. This paper proposes a locally adaptive 3D multi-resolution Nakagami-based fractal feature descriptor that extends Nakagami-based texture analysis to accommodate subtle speckle spatial frequency tissue intensity variability in volumetric scans. In order to reconstruct original signal it is necessary to find out statistics of the signal before and signal after compression. These applications include driving, airport security and control centers.

Experiments show that the proposed method does remove speckle noise significantly. Besides the traditional fields of Cardiology and Obstetrics, where it is extensively used for long time, it has became also very useful in the diagnosis of diseases of the prostate, liver and coronaries and carotids atherosclerosis. The technological innovations in the use of urethral warming devices and real-time transrectal ultrasound sonography have lead to effective tumor ablation with a reduction in the morbidity of the procedure. This paper presents fundamental and advanced ultrasonic tissue characterization and feature extraction methods for analyzing plaque. The importance of atherosclerotic disease in coronary artery has been a subject of study for many researchers in the past decade. This is the first state-of-the-art review to provide a comprehensive understanding of the field of ultrasonic vascular morphology tissue characterization.

In our work, we introduced a new method which reduces speckle noise in ultrasound images. By this, new techniques based on Ultrasound were introduced in the clinical practice for diagnosis and therapeutics, mainly in hospital facilities. It is your own responsibility to adhere to these terms. By this, new techniques based on Ultrasound were introduced in the clinical practice for diagnosis and therapeutics, mainly in hospital facilities. At this stage, the algorithm-1 is modeled as a region-based strategy using a classification framework, whereas the algorithm-2 is modeled as a boundary-based approach that uses the level set framework. However, tissue patterns can vary according to the utilized imaging system and are intrinsically correlated to the scale of analysis. Methods: Retrospective study on a database of 404 common carotid artery B-mode sonographic images from 202 diabetic patients.

After excluding 10 outliers, coefficient of correlation was 0. The extraction of useful information from Ultrasound data for diagnosis is a challenge task that makes this medical image modality a very active field of research.
