Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing.

Ultrasound is no different from 'normal' (audible) sound in its physical properties, except in that humans cannot hear it.

This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy, young adults.

Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease.

MRI scanners use strong magnetic fields, radio waves, and field gradients to generate images of the inside of the body.

Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology).

Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease.

Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities.

Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging.

Radiology is a specialty that uses medical imaging to diagnose and treat diseases seen within the body.

A variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging (MRI) are used to diagnose and/or treat diseases.

Interventional radiology is the performance of (usually minimally invasive) medical procedures with the guidance of imaging technologies.

A physician, medical practitioner, medical doctor, or simply doctor is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments.

Physicians may focus their practice on certain disease categories, types of patients and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice.

Medical practice properly requires both a detailed knowledge of the academic disciplines (such as anatomy and physiology) underlying diseases and their treatment—the science of medicine—and also a decent competence in its applied practice—the art or craft of medicine.
