Ultrasound scan, a pivotal component of modern medical diagnostics, utilizes high-frequency sound waves to produce real-time images of internal body structures. This non-invasive technique has revolutionized various medical fields, including obstetrics, cardiology, and abdominal imaging. By emitting sound waves into the body and capturing the echoes that bounce back, ultrasound creates detailed images without the need for radiation or invasive procedures. In obstetrics, ultrasound plays a fundamental role in monitoring fetal development during pregnancy. It allows healthcare providers to visualize the fetus's growth, detect abnormalities, and assess fetal well-being. Obstetric ultrasound helps confirm pregnancy, determine gestational age, and identify potential complications such as multiple pregnancies or fetal malformations. Moreover, it provides expectant parents with the opportunity to bond with their unborn child by witnessing real-time images of the fetus. In cardiology, ultrasound imaging, known as echocardiography, enables the assessment of the heart's structure and function. By visualizing heart chambers, valves, and blood flow patterns, echocardiograms aid in diagnosing various cardiac conditions, including coronary artery disease, heart failure, and valve disorders. Echocardiography is an essential tool for cardiologists to evaluate cardiac anatomy, detect abnormalities, and monitor the progression of heart disease in patients of all ages. Ultrasound is also widely used in abdominal imaging to examine organs such as the liver, gallbladder, pancreas, kidneys, and spleen. It helps detect abnormalities such as tumors, cysts, or gallstones and assists in diagnosing conditions affecting the digestive system and adjacent structures. Abdominal ultrasound is a valuable tool for detecting liver cirrhosis, gallbladder inflammation, pancreatic tumors, kidney stones, and other gastrointestinal disorders. Furthermore, ultrasound-guided procedures have become commonplace in clinical practice. Ultrasound provides real-time imaging guidance for needle placement during biopsies, aspirations, injections, and other minimally invasive interventions. This precise visualization of the target area enhances procedural accuracy, reduces the risk of complications, and improves patient outcomes. Ultrasound-guided procedures are performed across various medical specialties, including radiology, oncology, anesthesia, and pain management. The portability and versatility of ultrasound equipment make it a preferred imaging modality in diverse clinical settings. Unlike bulky imaging machines such as CT or MRI scanners, ultrasound devices are compact and easily transportable. This mobility allows healthcare providers to perform ultrasound scans at the bedside, in emergency departments, clinics, and even in remote or resource-limited areas where access to advanced imaging technology may be limited. Moreover, ultrasound imaging is considered safe for patients of all ages, including pregnant women and children. Unlike X-rays and CT scans, which use ionizing radiation, ultrasound emits harmless sound waves that do not pose a risk of radiation exposure. Additionally, ultrasound imaging does not require the use of contrast agents, minimizing the likelihood of allergic reactions or adverse effects. Despite its many advantages, ultrasound imaging has limitations. Factors such as patient body habitus, presence of air or gas in the body, and operator experience can affect the quality of ultrasound images. In certain cases, ultrasound may not provide sufficient detail or may be inconclusive, necessitating further imaging with modalities such as CT or MRI.

This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.

One of the first applications of ultrasound was in submarine sonar equip ment. Since then ultrasound has found increasing applications, particularly in industry, but increasingly in biomedicine. For many years ultrasound has been used in physical therapy, although only in the past decade or two has it evolved from laboratory curiosity to a well-established diagnostic imaging modality. Ultrasound is now a widely accepted, indeed pervasive, diagnos tic and therapeutic tool in the medical field, and its applications are increasing rapidly. Our intent in developing this book is to provide a coherent tutorial intro duction to the field of medical ultrasound at a level suitable for those en tering the area from either medical or scientific backgrounds. The topics discussed should be of interest to nearly all medical and health care per sonnel needing to understand or operate ultrasonic devices, including clini cians, medical technicians, physiotherapists, medical physicists, and other biomedical scientists interested in the field. The book opens with a description of the basic principles of propagating acoustic waves, explains how they interact with a wide range of biological systems, and outlines the effects they produce. To provide practical infor mation to operators of ultrasound equipment, we have included thorough coverage of the details of ultrasonic instrumentation and measurement techniques, and set forth the framework for an effective quality assurance program.

A didactic, illustrated guide to the use of ultrasound as a diagnostic tool in clinical practice. Prepared by an international group of experts with wide experience in both developed and developing countries, the manual responds to the need for a basic reference text that can help doctors, sonographers, nurses, and midwives solve imaging problems when no experts are available. With this need in mind, the manual adopts a practical approach aimed at providing a thorough grounding in both the techniques of ultrasound and the interpretation of images. The need for extensive supervised training is repeatedly emphasized. Because the clinical value of ultrasound depends so greatly on the experience and skill of the operator, the manual makes a special effort to alert readers to common pitfalls and errors, and to indicate specific clinical situations where ultrasound may not be helpful or reliable as a diagnostic tool. Explanatory text is supported by numerous practical tips, warnings, checklists and over 600 illustrations. The opening chapters explain how ultrasound works, outline the factors to consider when choosing a scanner, and introduce the basic rules of scanning, including advice on how to recognize and interpret artefacts. Guidance on the selection of ultrasound equipment includes clear advice concerning where costs can be spared and where investment is essential. The core of the manual consists of seventeen chapters providing guidance on scanning techniques and the interpretation of images for specific organs and anatomical sites, with the most extensive chapter devoted to obstetrics. Each chapter contains illustrated information on indications for scanning, preparation of the patient, including choice of transducer and setting of the correct gain, general scanning techniques, and specific techniques for identifying anatomical landmarks and recognizing abnormalities. The manual concludes with WHO specifications for a general purpose scanner judged entirely suitable for 90-95% of the most common ultrasound examinations.
