4. Ultrasound imaging: What does it look like?

5. Ultrasound imaging: development of a pregnancy 8 weeks gestation (out of a 40 week pregnancy) 18 weeks 24 weeks

6. Ultrasound imaging: foetus feet This is a 2D ultrasound scan through the foot of a foetus. You can see some of the bones of the foot. We can process the image in a computer to find the outline of the foot. This is called surface rendering. Here, the foot has been surface rendered

7. Ultrasound imaging: more surface rendering

8. Ultrasound image of foetus used with Chapter 1
