Thermography imaging uses energy emitted by the body in which form?

• A. Heat energy
• B. Light energy
• C. Sound energy
• D. Magnetic energy

Answer: (A)

Thermography detects infrared radiation emitted by the body as heat. At typical body temperatures, the human body radiates energy mainly in the infrared region of the spectrum. A thermographic camera senses this infrared (thermal) energy and converts it into an image that shows surface temperature differences. This is why heat energy is the correct form: it’s the body’s own thermal radiation being measured, not visible light, sound, or magnetic energy.
