My master’s thesis was on a non-intrusive neonatal imaging method called optical tomography.
When finished, it will help doctors diagnose newborn babies from brain injury caused by breathing difficulties or other problems that prevent the baby from receiving sufficient amounts of oxygenated blood during birth.
While I was only involved with calibrations of the instrument being developed, I have always stayed interested in non-intrusive imaging methods.
That is why it was a double joy to join my wife the other day for a 4D ultrasound scan session of our little baby boy.
Traditional ultra sound just shows a thin slice of the baby in the mothers womb and is often seen in profile.
With 3D ultrasound, a series of slices is taken in a short amount of time (2s?). The slices are then combined and are visualised as a volume (3D).
4D just means that the volume of images can be seen moving in real time. The video is a bit jerky due to the 2 second scanning sweep but nevertheless it is breathtakingly clear.
The 4D scan was performed at the Create Health London Clinic and I can highly recommend them for being very professional..
