In medical terminology, which suffix indicates an instrument used to record an image?

Explanation:
Suffix -graph signals an instrument that records something, often producing a graphic image or trace. The root graph means to write or record, so a device named with -graph is one that captures data or an image—like an electrocardiograph that records the heart’s electrical activity or an angiograph that records images of blood vessels. In contrast, -meter denotes a measuring device, -scope is for viewing or examining, and -itis means inflammation. So the best choice is the suffix -graph because it designates an instrument used to record an image.
