Sonography

Sonography

Ultrasound scans / Sonography works on the principle of sound reflection. It generates high-frequency sound waves to create images in 2D, 3D and 4D. The images can be viewed as pictures on a video screen/monitor. 3D and 4D ultrasounds are widely used in obstetric practice. A 3D ultrasound creates a different perspective by merging a series of 2D images taken from various angles into a composite to form a 3D picture. 4D ultrasound is different from a 3D ultrasound because it adds the dimension of time, providing a live video of the baby in action: kicking, stretching, yawning, and sucking their thumb.
