Module 1 - Self test

What increases the absorbed dose in radiography?

Increasing mA

How does the variation in kVp influence the contrast in X-ray imaging?

Lower kVp increases contrast because of increased attenuation.

How does adjusting the kVp influence the X-ray image characteristics and patient dose?

Decreasing kVp reduces scatter and noise, enhancing detail and reducing dose.

In the context of X-ray imaging, how does mAs affect the quality of the image produced?

Higher mAs results in increased image brightness and potentially increased patient dose.

What is the effect of increased mAs (milliampere seconds) on the quality of X-ray imaging?

No change in beam quality but increased detail due to increased scatter.

What is the impact of increasing the Source-to-Image Distance (SID) on detail in X-ray imaging?

It increases due to less magnification

What happens when you increase collimation, resulting in a smaller field size in radiographic imaging?

Patient dose decreases due to less volume of tissue irradiated.
