The four main types of ultrasound scanning techniques are:
- 2D Ultrasound (B-mode): Produces two-dimensional images of internal structures, providing a flat, cross-sectional view.
- 3D Ultrasound: Creates three-dimensional images, offering a more detailed view of internal structures by reconstructing multiple 2D images.
- 4D Ultrasound: Provides real-time 3D imaging, allowing visualization of movement within the body, such as fetal movements.
- Doppler Ultrasound: Measures and visualizes the flow of blood within vessels, showing the direction and speed of blood flow using color or spectral Doppler.
