This book was released on 2016-11-21 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the development of quantitative techniques for ultrasound and photoacoustic imaging in the assessment of architectural and vascular parameters. It presents morphological vascular research based on the development of quantitative imaging techniques for the use of clinical B-mode ultrasound images, and preclinical architectural vascular investigations on quantitative imaging techniques for ultrasounds and photoacoustics. The book is divided into two main parts, the first of which focuses on the development and validation of quantitative techniques for the assessment of vascular morphological parameters that can be extracted from B-mode ultrasound longitudinal images of the common carotid artery. In turn, the second part highlights quantitative imaging techniques for assessing the architectural parameters of vasculature that can be extracted from 3D volumes, using both contrast-enhanced ultrasound (CEUS) imaging and photoacoustic imaging without the addition of any contrast agent. Sharing and summarizing the outcomes of this important research, the book will be of interest to a broad range of researchers and practitioners in the fields of medical imaging and biomedical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Diagnostic and Therapeutic Ultrasound has recently taken an explosive growth for better safer, economic, mobile and high quality healthcare. 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. Its low cost, when compared with other medical image modalities, makes it one of the preferred tools for medical monitoring, follow-up and diagnosis. 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. However, Ultrasound images present poor quality, very low signal to noise ratio and a lot of artifacts. 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. The difficulties are being overcome and novel and advanced methods are being proposed for detection, characterization and segmentation of abnormalities in several organs. 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. This book presents some of the recent advances in Ultrasound imaging technology covering several organs and techniques in a Biomedical Engineering (BME) perspective. The focus of the book is in the algorithms, methodologies and systems developed by multidisciplinary research teams of engineers and physicians for Computer-Aided Diagnosis (CAD) purposes. Cardiovascular and Cancer, the most common life-threatening diseases in western countries, are two of the most important topics focused in the book. However, other advanced issues are also presented such as Intravascular Ultrasound, 3D US and Ultrasound in Computer-Aided Surgery (CAS). Some chapters are direct contributions from medical research groups where Ultrasound has also received great attention in the last decade. By this, new techniques based on Ultrasound were introduced in the clinical practice for diagnosis and therapeutics, mainly in hospital facilities.

Available in PDF, EPUB and Kindle. Book excerpt: Elastography, the science of creating noninvasive images of mechanical characteristics of tissues, has been rapidly evolving in recent years. The advantage of this technique resides in the ability to rapidly detect and quantify the changes in the stiffness of soft tissues resulting from specific pathological or physiological processes. Ultrasound elastography is nowadays applied especially on the liver and breast, but the technique has been increasingly used for other tissues including the thyroid, lymph nodes, spleen, pancreas, gastrointestinal tract, kidney, prostate, and the musculoskeletal and vascular systems. This book presents some of the applications of strain and shear-wave ultrasound elastography in hepatic, pancreatic, breast, and musculoskeletal conditions.

Download or read book Quantitative Ultrasound Imaging During Ablation Procedures written by Kayvan Samimi and published by . This book was released on 2017 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional ultrasound imaging (i.e. B-mode sonogram) is a qualitative mode of imaging based on visualizing the relative echogenicity of different tissue types within the body. This useful mode of imaging has aided clinicians for more than 50 years. However, B-mode imaging does not capture any of the frequency-dependent information that is contained within the ultrasound echo signal. Additionally, due to its qualitative nature, there is much inter-system and inter-observer variability with regard to generation and interpretation of B-mode images. Quantitative Ultrasound (QUS) methods have been developed to extract additional information by estimating acoustic properties of tissue from the frequency-domain representation of echo signals. These estimates can be converted to color-coded maps that are visualized along with conventional B-mode images to form enhanced ultrasound images. Such images can potentially provide valuable diagnostic and prognostic information to medical professionals. Some of the more important acoustic parameters of interest in QUS and tissue characterization are the ultrasonic attenuation coefficient and the backscatter coefficient. Attenuation has been studied as a potential classifier of normal and pathological liver tissue. In addition to providing pathological information for diagnosis, monitoring these QUS parameters during therapeutic procedures such as tumor ablation can lead to targeted and optimized treatment. The goals of this dissertation are to theoretically model and analyze current methods of acoustic attenuation estimation; improve attenuation estimation algorithms to enhance the quality of subsequent QUS images; and correlate changes in QUS parameter values with progression of thermally ablative procedures for ex-vivo and in-vivo liver ablations. Although QUS imaging may be used to assist clinicians in various stages of diagnosis and treatment of diseases in a multitude of bodily organs and tissue types, this dissertation focuses on thermal ablation of primary or metastatic liver tumors in order to showcase the possible benefits of the proposed estimation methods and to compare their performance with existing estimation techniques. Additionally, simulated and physical tissue-mimicking (TM) phantoms with known acoustic properties are used to statistically test and compare the accuracy and precision of these methods. Theoretical analysis and experimental results suggest that our proposed method for estimation of the ultrasonic attenuation coefficient based on measurement of frequency shifts in a normalized power-spectral representation of the ultrasonic echo signal is best suited to in-vivo QUS imaging in clinical settings and provides estimates with standard deviations that are at least three times smaller than was previously possible with other methods.

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 Analysis of the Potential for Coded Excitation to Improve the Detection of Tissue and Blood Motion in Medical Ultrasound written by Benjamin Lamboul and published by . This book was released on 2010 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doppler ultrasound imaging modalities arguably represent one of the most complex task performed (usually in real time) by ultrasound scanners. At the heart of these techniques lies the ability to detect and estimate soft tissues or blood motion within the human body. As they have become an invaluable tool in a wide range of clinical applications, these techniques have fostered an intensive effort of research in the field of signal processing for more than thirty years, with a push towards more accurate velocity or displacement estimation. Coded excitation has recently received a growing interest in the medical ultrasound community. The use of these techniques, originally developed in the radar field, makes it possible to increase the depth of penetration in B-mode imaging, while complying with safety standards. These standards impose strict limits on the peak acoustic intensity which can be transmitted into the body. Similar solutions were proposed in the early developments of Doppler flow-meters to improve the resolution / sensitivity trade-off from which typical pulsed Doppler systems suffer. This work discusses the potential improvements in resolution, sensitivity and accuracy achievable in the context of modern Doppler ultrasound imaging modalities (taken in its broadest sense, that is, all the techniques involving the estimation of displacements, or velocities). A theoretical framework is provided for discussing this potential improvements, along with simulations for a more quantitative assessment. Colour Flow Imaging (CFI) modalities are taken as the main reference technique for discussion, due to their historical importance, and their relevance in many clinical applications. The potential achievable improvement in accuracy is studied in the context of modern velocity estimation strategies, which can be broadly classified into narrowband estimators (such as the "Kasai" estimator still widely used in CFI) and time shift based wideband strategies (normalised crosscorrelation estimator used, for instance, in applications like strain or strain rate estimation, elastography, etc.). Finally, simulations and theoretical results are compared to experimental data obtained with a simple custom-designed experimental set-up, using a single-element transducer.

Available in PDF, EPUB and Kindle. Book excerpt: Ultrasound imaging is a clinical imaging technique that provides real-time, quantitative anatomical and physiological information in humans. It can serve both diagnostic and therapeutic functions. The diagnostic ultrasound is a non-invasive technique that uses sound waves to scan the structures or parts within the body. Ultrasound images can capture the movement of the internal organs, fetus and blood flow through the vessels inside the body. There are several medical applications of ultrasound, which include monitoring the development and health of the fetus during pregnancy. A Doppler ultrasound is used to assess the movement of blood to parts of body such as the heart, placenta and testes. Therapeutic ultrasound can be used to alleviate pain from the spread of cancer into the bones (bone metastases). Some other applications of ultrasound imaging include treatment of uterine fibroids and prostate surgery. Various studies that are constantly contributing towards advancing technologies and evolution of this field have been examined in detail within this book. It brings forth some of the most innovative concepts and elucidates the unexplored aspects of ultrasound imaging. The book will provide comprehensive knowledge to the readers.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The structure and function of tissue microcirculation are critical in most major disease developments and in the patient-specific treatment response. Adequate quantitative characterization of tissue microvasculature may therefore assist to better understand various types of disorders, to develop new therapeutic strategies, and to monitor early response to therapy. Currently, the greatest challenge is to accurately and precisely quantify the microvascular properties in a noninvasive manner. To address this challenge, this dissertation proposes characterizing the tissue microvascular network morphology using contrast-enhanced ultrasound (CEUS). We hypothesize that the development of morphological image analysis methods using CEUS images will improve in vivo quantitative analysis of tissue microvascular networks for early treatment monitoring. This work demonstrates (1) the potential of CEUS-derived morphological features as a predictor of anti-cancer therapy response, (2) the development and use of multiparametric CEUS image analysis, and (3) the implementation of three-dimensional superresolution US visualization and quantification using advanced image analysis methods.
