Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the concept of medical ultrasound imaging and discusses array signal processing in ultrasound. Signal processing using different beamforming techniques in order to achieve a desirable reconstructed image and, consequently, obtain useful information about the imaging medium is the main focus of this book. In this regard, the principles of image reconstruction techniques in ultrasound imaging are fully described, and the required processing steps are completely expanded and analyzed in detail. Simulation results to compare the performance of different beamformers are also included in this book to visualize their differences to the reader. Other advanced techniques in the field of medical ultrasound data processing, as well as their corresponding recent achievements, are also presented in this book. Simply put, in this book, processing of medical ultrasound data from different aspects and acquiring information from them in different manners are covered and organized in different chapters. Before going through the detailed explanation in each chapter, it gives the reader an overview of the considered issue and focuses his\her mind on the challenge ahead. The contents of the book are also presented in such a way that they are easy for the reader to understand. This book is recommended for researchers who study medical ultrasound data processing.
Download or read book Ultrasound B mode Imaging Beamforming and Image Formation Techniques written by Giulia Matrone and published by MDPI. This book was released on 2019-10-04 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasound medical imaging stands out among the other diagnostic imaging modalities for its patient-friendliness, high temporal resolution, low cost, and absence of ionizing radiation. On the other hand, it may still suffer from limited detail level, low signal-to-noise ratio, and narrow field-of-view. In the last decade, new beamforming and image reconstruction techniques have emerged which aim at improving resolution, contrast, and clutter suppression, especially in difficult-to-image patients. Nevertheless, achieving a higher image quality is of the utmost importance in diagnostic ultrasound medical imaging, and further developments are still indispensable. From this point of view, a crucial role can be played by novel beamforming techniques as well as by non-conventional image formation techniques (e.g., advanced transmission strategies, and compounding, coded, and harmonic imaging). This Special Issue includes novel contributions on both ultrasound beamforming and image formation techniques, particularly addressed at improving B-mode image quality and related diagnostic content. This indeed represents a hot topic in the ultrasound imaging community, and further active research in this field is expected, where many challenges still persist.

Download or read book Efficient Two pass Beamforming Applied to Ultrasound Imaging written by Hichem Rehouma and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, the application of adaptive beamforming methods to medical ultrasound imaging has become a field of increased interest, due to their ability to achieve superior ultrasound image quality. Such enhancements, however, come at a high computational cost. This thesis attempts to address the following simple question: Can we maintain a superior image quality while reducing the computational cost of adaptive beamforming? Our goal is to effectively combine low-complexity nonadaptive beamforming, such as the Delay-and-Sum (DAS) technique, with high-complexity adaptive beamforming, such as the Minimum variance Distortionless Response (MVDR) technique, implemented using the Generalized Sidelobe Canceller (GSC), to obtain high-quality images at low computational cost. We propose a simple two-pass beamforming scheme for that purpose. During the first pass, our scheme processes buffered input vectors using the inexpensive DAS method and computes the corresponding envelope. Based on that envelope information, selected outputs may be recomputed during the second pass (to improve beamforming performance) using the expensive GSC beamforming method. The purpose of the first pass is to identify which nonadaptively beamformed outputs can be spared from a heavy computational load of adaptive beamforming taking place in the second pass. We have evaluated our scheme using simulated ultrasound images of a 12-point phantom and a point-scatterer-cyst phantom, achieving substantial threshold-dependent computational savings without significant degradation in image resolution and contrast, compared to pure GSC beamforming.
Download or read book Frequency Smoothed Robust Capon Beamformer Applied to Medical Ultrasound Imaging written by Xian Long and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, adaptive array beamforming has been applied to medical ultrasound imaging and achieved promising performance improvement. However, the current robust Capon beamformer with spatial smoothing (RCB-SS) is implemented in the time domain, which does not fully utilise the large bandwidth of ultrasound signals and spatial smoothing reduces the effective aperture. In this dissertation, we propose a robust Capon beamformer with frequency smoothing (RCB-FS) and compare its performance with RCB-SS. To further reduce the speckle noise and utilise the large bandwidth of the signal, we combine RCB-FS and frequency com- pounding (FC) and propose a robust Capon beamformer with frequency smoothing combined with frequency compounding (RCB-FS-FC). The proposed RCB-FS method shows a narrower mainlobe width, lower sidelobes, better reconstruction at higher depths and less speckle than RCB-SS. FC is an e ective method to improve the contrast resolution and suppress speckle noise by combining sub-band images, at the expense of resolution. Compared to standard FC, the proposed RCB-FS-FC method has a better contrast resolution and speckle reduction and a significant improvement in resolution. RCB-FS offers a promising approach to find the optimal weights for the transducers in forming the sub-band images needed for frequency compounding.
