This book was released on 2007 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose. This thesis presents a study on the design of new eigen-based signal processing methods for use in color flow imaging. Specifically, the proposed methods are designed to address three main problems in color flow signal processing: the lack of abundant Doppler data samples, the possible presence of wideband Doppler clutter, and the potential flow signal distortions that arise during clutter suppression. Theoretical contributions. A clutter filter (the Hankel-SVD filter) and a flow estimator (the Matrix Pencil method) were respectively developed by exploiting the eigen-space principles related to two matrix forms known as the Hankel matrix and the matrix pencil. Both techniques were then combined to form a new color flow data processor that performs flow detection and flow estimation in parallel. All of these methods are adaptive to the Doppler signal contents through an SVD of the Hankel matrix created from a Doppler data vector. Moreover, they are intended to work with each Doppler ensemble separately (i.e. they do not require Doppler ensembles from multiple sample volumes). Experimental assessment. Color flow datasets were obtained respectively from a steady-flow phantom and from the carotid arteries of a youth subject. These datasets were used to analyze the performance of the proposed single-module processor. For the flow phantom study, the single-module processor showed that it can reconstruct velocity maps similar to the theoretical flow profile. As well, for the in vivo studies, it gave a better flow detection performance than conventional two-module processors especially when there is substantial tissue motion. Simulation assessment. A Doppler signal simulation model was developed to generate Doppler signals consisting of non-stationary (phase-modulated) tissue clutter and spectral-broadened (amplitude-modulated) flow echoes. The synthesized datasets were used to analyze the Hankel-SVD filter's flow detection performance and the Matrix Pencil's velocity estimation performance. A comparison of the Hankel-SVD filter with an existing type of adaptive filter (clutter-downmixing filter) showed that this new filter is more capable of discriminating flow echoes from Doppler clutter. Also, it was found that the Matrix Pencil can provide less biased flow estimates as compared to other frequency-based flow estimators like the lag-one autocorrelator.

This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed as a definitive report on current capabilities of ultrasound imaging and Doppler evaluation of the cerebral circulation, both extracranial and intracranial. The basic chapters are directed to the beginner in ultrasound and hemodynamics and for the expert in updating newly available modalities and techniques new to the field. The ultrasonic and hemodynamic principles are presented for physicians and vascular technologists in a practical way to avoid unnecessary mathematics. The aim is for maximum clinical utilization so that available equipment may be used more efficiently and provide more accurate diagnosis.

Download or read book Color Doppler Flow Imaging written by J.R. Roelandt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of quantitative Doppler echocardiography gave rise to explo sive interest in the application of this method in clinical cardiology. However, before cardiologists could fully validate its clinical utility, they were confronted with a further development, namely color-coded Doppler flow imaging. This new technique allows a comprehensive study of the direction, velocity, uniformity and timing of intracardiac blood flow, while simultaneously revealing cardiac struc tures and their movement. 'Color Doppler' facilitates the diagnosis of a variety of cardiac conditions, and an overwhelming amount of information is available at any instant. Interpretation of these fascinating images requires a substantial experience and theoretical background. This monograph updates the application of color Doppler to both congenital and acquired heart disease. The work comprises 15 chapters written by authorities in the field, each of whom presents his most recent experience in the field. In addition, further advantages in the clinical use of pulsed and continuous wave Doppler in pediatric and adult cardiol ogy are presented. This book contains, of course, many color plates. 1.

Available in PDF, EPUB and Kindle. Book excerpt: Duplex Sonography is the first comprehensive text written about this modality. The book offers the reader detailed information about all major uses of duplex and is introduced by a brief chapter on the physical principles of doppler ultrasound as it relates to duplex scanning. Duplex Sonography is intended to provide relevant information on all aspects of the technique, ranging from the basics of performing the examination to the features of sometimes complex pathological states. The book is intended for anyone interested in non-invasive vascular diagnosis including radiologists, vascular surgeons and ultrasound/peripheral vascular technologists. Other groups may find individual chapters appealing: carotid/cardiac sonography for cardiologists, fetal sonography for obstetricians or carotid sonography for neurologists. Each chapter is not only a guide to duplex evaluation, but also provides valuable information about vascular dynamics of the organ system under discussion. Physicians or technologists reading this book should come away with a well-rounded background in state-of-the-art duplex sonography and will undoubtedly discover new possibilities for using this non-invasive vascular technique.
