Okay kiddo, have you ever seen a picture of your bones at the doctor's office? That's called an X-ray!
Digital radiography is a newer way of taking X-rays that uses a special machine that doesn't need as much radiation as the old machines. That's important because too much radiation can be harmful to your body.
With digital radiography, the X-rays go through your body and hit a special sensor that's connected to a computer. The computer takes all the information from the sensor and turns it into a picture that the doctor can see on a screen.
One of the coolest things about digital radiography is that the picture can be adjusted and enhanced so the doctor can see more details. And since it's all saved on the computer, the doctor can easily look back at the image later if they need to.
So, digital radiography is a fancy way of taking X-rays that's safer for you and easier for the doctor to look at. Pretty neat, right?
