What is a digital X-ray?

A digital X-ray, or digital radiography, is a modern type of X-ray that utilises digital sensors instead of photographic film, as with a traditional X-ray. The image captured is converted to digital data immediately and is available for review within seconds.

What are the two types of digital xray?

There are two types of digital imaging systems used in intraoral radiography – computed radiography (CR) and direct radiography (DR). CR uses a photostimulable phosphor (PSP) plate to capture the image.

X-ray is one of the modern imaging techniques including ultrasound, CT scan and MRI which shows structure inside the human body.

Advantages of X-Ray

Following are the advantages of X-Ray:

✦ It is cheaper and simple technique.

✦It has lower radiation compare to CT scan.

✦ X-rays are not absorbed very much by air, hence specimen need not be in an evacuated chamber.

Conclusion :

✦ Though X-rays are not 100% safe, they are very useful for diagnosis if used in safest and controlled environments as much as possible.
