Frequently Asked Questions: Image Quality
Q: My X-Ray Images don't look right. The teeth appear to be too sharp, as if they've been
chopped-off at the top. What's the deal?
A: Normally, this is a result of an X-ray exposure that simply went too long. The best (and simplest) solution is
to reduce the amount of time of the exposure.
Q: Why are my X-Ray Images so grainy-looking?
A: Images that have too much "noise" are often under-exposed. Users should INCREASE the exposure time.
Q: Doesn't the Prof. Suni software allow for Noise Reduction?
A: Yes. You can manually adjust a number of variables, including Noise. When in Prof. Suni, select
Tools > Options > Sensor. Select your sensor from the list, and you will see several tabs specific to
image quality, including NOISE REDUCTION. Please note: you will require the password to modify any settings.
Q: I've been adjusting my settings on the X-Ray Unit, but aren't there some things I can
do in the Prof. Suni software to enhance or correct image quality?
A: Yes, there are. In fact, the Prof. Suni software offers a large number of filters and image enhancing
functions that will improve the overall image quality, enhance problem areas, correct contrast, etc. These
features can make a significant difference. But we often recommend that users focus on obtaining a fundamentally
"good" X-Ray by employing sound techniques and good practices. In other words, you should start by getting the
best X-Ray image possible; after that, you can improve on an already good image.
Q: Will changing the EXPOSURE TIME on the X-Ray unit affect image quality?
A: Yes. Users should remember that different areas of the mouth may require exposure times to be adjusted. For
example, Upper Teeth will normally require a longer exposure than lower teeth; Molars will also require a longer
exposure time; Front teeth will require a shorter exposure. One of the rules of thumb is that generally, the
farther back you go, the longer the exposure should be.
