Hesi Image Production Questions and Answers | Latest Version | 2025/2026 | Correct & Verified
What is the effect of increasing SID on image sharpness?✔✔It increases sharpness.
What is the effect of a high-ratio grid on scatter cleanup?✔✔It improves scatter cleanup but increases patient dose.
What is the relationship between pixel size and image resolution?✔✔Smaller pixels increase image resolution.
What is the function of automatic exposure control (AEC)?✔✔To terminate the exposure when enough radiation has reached the detector.
What is the purpose of filtration in X-ray tubes?✔✔To remove low-energy photons that increase patient dose without improving image quality.

What is the effect of underexposure in digital radiography?✔✔It produces a noisy or grainy image.
What is the primary factor that controls the overall blackness of a radiographic image?✔✔mAs (milliampere-seconds).
What is the main factor that influences radiographic contrast?✔✔kVp (kilovolt peak).
What happens to image detail when patient motion occurs during exposure?✔✔It decreases image sharpness.
What effect does increasing SID (source-to-image distance) have on magnification?✔✔It decreases magnification.
What is the effect of increasing OID (object-to-image distance) on image sharpness?✔✔It decreases image sharpness and increases magnification.

What is the function of a grid in radiographic imaging?✔✔To reduce scatter radiation and improve contrast.
What happens to patient dose when a grid is used without adjusting exposure?✔✔Patient dose increases.
What is the term for the unsharp edges of an image?✔✔Penumbra.
What effect does a small focal spot size have on recorded detail?✔✔It increases sharpness of the image.
What is the effect of increasing kVp on image contrast?✔✔It lowers contrast (long scale of gray).
