The study of ultrasound, commonly referred to as ultrasound studies, encompasses the physics of high-frequency sound waves, the design of transducers and imaging systems, and the clinical and research applications of diagnostic and therapeutic ultrasound. It bridges engineering, physiology, and medicine to enable noninvasive visualization and treatment.

Ultrasound uses frequencies from about 1 to 20 megahertz and relies on piezoelectric transducers to generate and receive echoes. Imaging modalities include B-mode (grayscale) imaging, M-mode for motion, and Doppler techniques to assess flow and velocity. Advances include color and power Doppler, elastography to measure tissue stiffness, three-dimensional and four-dimensional imaging, and contrast-enhanced ultrasound with microbubble agents. Equipment integrates imaging probes, processing software, and display interfaces to produce real-time results.

Clinically, ultrasound studies cover obstetrics and gynecology, abdominal imaging, cardiac echocardiography, vascular studies, and musculoskeletal or small parts such as thyroid and breast. Therapeutic ultrasound uses focused ultrasound to ablate or modulate tissue and is part of image-guided interventions and pain management. Emerging areas include high-intensity focused ultrasound (HIFU) and noninvasive neuromodulation.

Education and practice typically involve physicians, radiologists, sonographers, and researchers. Training emphasizes anatomy, physics, instrumentation, and scanning technique, with certification and continuing education common in many regions. Safety guidelines follow ALARA principles to minimize exposure and heating, while recognizing that ultrasound is generally considered safe when used appropriately.

Current research directions include artificial intelligence for automated image interpretation, portable handheld devices for point-of-care ultrasound, fusion imaging that combines ultrasound with CT or MRI data, and improved contrast agents and elastography methods to expand diagnostic and therapeutic capabilities.
