Medical ultrasonography (sonography) is an ultrasound-based diagnostic imaging technique used to visualize muscles and internal organs, their size, structures and possible pathologies or lesions. In physics the term 'ultrasound' applies to all acoustic energy with a frequency above human hearing (20,000 hertz or 20 kilohertz). The choice of frequency is a trade-off between spatial resolution of the image and imaging depth: lower frequencies produce less resolution but image deeper into the body. Typical diagnostic sonographic scanners operate in the frequency range of 2 to 18 megahertz, hundreds of times greater than this limit. In physics the term 'ultrasound' applies to all acoustic energy with a frequency above human hearing (20,000 hertz or 20 kilohertz). There are a plethora of diagnostic and therapeutic applications practiced in medicine. Obstetric sonography is commonly used during pregnancy and is widely recognized by the public. Typical diagnostic sonographic scanners operate in the frequency range of 2 to 18 megahertz, hundreds of times greater than this limit.
