Which type of x-rays create diagnostic?

• A. Primary
• B. Secondary
• C. Scatter
• D. Backscatter

Answer: (A)

The diagnostic image is created by the primary X-ray beam—the useful photons emitted by the tube that pass through the patient and reach the detector. These photons carry the true information about tissue attenuation and produce the contrast seen in radiographs. Other photons arise after the primary beam interacts with matter: secondary radiation, scatter, and backscatter are generated within the patient or toward the source and typically degrade image quality or add dose rather than form the main image. So the primary beam is the ones that create the diagnostic X-ray.
