** is having a city scan on his head. What is it, an injection?
(injections are merciless medical procedures according to the gentleman)
CT Scan. Doctors take photos of the inside of the body using special lights called x-rays…
I know X-ray, it takes picture of bones.
Yes, but CT Scan is slightly different. Can you bring your skeleton model?
OK.
Now, this is the skull. If you take x-ray photo of the head, you get a picture of the skull, since X-ray is err.. like you said, see through photo. You cannot get a good picture of the brain inside the skull using x-rays because skull is made of hard bones.
OK.
CT Scanners use x-rays to take several pictures, then do mathematical calculations and create a good picture of the brain.
Addition or subtraction?
Much more complicated mathematics called calculus, you will learn it when you are go to high school.
My school is not big enough to teach that?
I mean when you are in higher classes.
Fine.
Now you know what CT Scan is?
Yes- photos and mathematics.
Well, photos created using x-rays and mathematics, for doctors to check if something inside is OK or not. We will go to Youtube and watch the video of a CT Scan. This is the patient, in he goes into the machine that will take x-ray images and the lady who is operating the machine is called…
Maths teacher!
Er.. well, the maths bit of it was done by a great maths teacher called Penrose and it is all in the computer now. The person who is doing the scan is called Radiologist. Radiologist will do the same procedure for * also.
Wow, only she knows how to do this!
Only who?
This Radio… what's her name again?
Radiologist is the name of the job, not this lady’s name!!!
