A-scan: This type of ultrasound is often used in ophthalmology. It provides a one-dimensional view, showing the distance between the front and back of the eye.

B-scan: This is a two-dimensional ultrasound scan. It is used to create a cross-sectional view of the eye and other parts of the body.

Real-time scan: This type of ultrasound scan provides a live view, allowing doctors to see the movement of the body's internal organs as well as blood flowing through blood vessels.

3D and 4D scan: These scans provide three-dimensional images. The difference between the two is that 4D scans show movement in real time (the 4th dimension is time), so it's like watching a live video of the inside of the body.

Doppler scan: This type of ultrasound scan is used to measure and assess blood flow. It can detect blocked or reduced blood flow in the major arteries and veins.
