is a branch of medical imaging which utilises high frequency sound waves to visualise the internal organs and soft tissues in the human body. The internal organs, such as liver, kidneys, heart, etc. are seen in real time. Ultrasound examination is also ideal for providing information about muscles, joints, tendons and ligaments.
Obstetric sonography is a vital part of ultrasound. This involves the visualisation of the foetuses during routine and emergency prenatal care.
Today ultrasound is used to diagnose a wide range of medical conditions:
where the probe (transducer) has two 2D planes that are perpendicular to each other, providing more efficient localization and detection of the area of interest. An omniplane probe is the one that can rotate 180° to obtain multiple images.
In 3D ultrasound, many 2D planes are digitally processed and added together with the help of a special software to create a 3-dimensional image of an object.
