Imagine you're trying to take a picture of your favorite toy through a foggy window, that’s like radiographic imaging!
When doctors use X-rays, they’re sending tiny invisible messages through the body, just like whispers traveling from one side of the room to the other. These whispers help create a picture on special paper or a screen. But sometimes, those whispers get a little messed up, that’s when distortion and artifacts happen!
What is Distortion?
Distortion is like when you draw a straight line on a piece of paper but then stretch it out, the line becomes wobbly or squished! In imaging, this can make parts of the picture look stretched or bent. It’s like if your toy looked funny because the foggy window made it seem bigger or smaller than it really was.
What Are Artifacts?
Artifacts are extra things that show up in the image, kind of like a smudge on your toy's face when you try to draw it. They can be caused by things like movement, clothes, or even the machine itself. These strange little guests might make the picture look a bit confusing, but doctors know how to read them and still find what they’re looking for!
Examples
- A broken X-ray image looks blurry because the machine didn't capture all the details clearly.
