Question

Which types of images are produced by X-rays?

• A. 3D image
• B. 3D image
• C. 2D image
• D. 4D image

Hint:

X-ray = projection imaging → always 2D.

Answer 1

The Correct Option is C

Step 1: X-ray imaging principle.
X-rays penetrate tissues differentially, creating a projection image based on absorption.

Step 2: Image formation.
Dense structures block more X-rays, producing contrast on a flat detector.

Step 3: Nature of the result.
The output is a flat, two-dimensional projection.

Step 4: Comparison with volumetric techniques.
CT and MRI generate 3D/4D datasets; conventional X-rays do not.

Step 5: Conclusion.
X-rays produce 2D images.
