Frequently Asked Questions

Why do doctors and dentists use CBCT as

part of their radiographic armamentarium?

 

~ X-rays are an established and essential part of every dental practice.

 

~ A CBCT scan provides dentists with views that were previously

unavailable other than through medical CT.

 

~ CBCT offers views of patient anatomy in three dimensions, without the magnification, distortion, and superimposition.

 

~ The precision of CBCT scans assists in precise diagnosis and treatment plans with the goal of better clinical outcomes.

 

~ The effective dose from a standard i-CAT scan† is at least 10 times less radiation than that from a medical CT of the skull used for dental purposes.

 

It is important to note that clinicians make the decision on when a case warrants a CBCT scan and on what settings to use for the specific patient’s needs, based on their clinical expertise and ALARA principles.

What does ALARA stand for?

 

As Low As Reasonably Achievable - Term coined to regulate allowable amount of radiation dose in x-ray images.  Scan the area of interest with the least amount of radiation possible.

How do natural, dental, and medical radiation levels compare?

 

CBCT technology exposes patients to a lower radiation dose than a number of other imaging modalities and far less than medical CT. The following tables provide dose comparisons for natural and medical radiation exposures.

What are the i-CAT features that reduce radiation & allow for the management of emitted radiation?

 

~ Settings enable the user to take a lowered-dose scan that emits less radiation than the above-mentioned standard i-CAT scan.

 

~ Pulsed-beam technology employed by i-CAT produces lower radiation than continuous beam technology by only activating the x-ray source when the panel is ready to capture an image.

 

~ Collimation is standard on all i-CAT systems, providing the ability to limit the radiation exposure to the specific area of interest.

 

~ Voxel selection to adjust resolution and radiation exposure is based on clinical need.

 

~ Selectable traditional 2-D panoramic mode; digital panoramic effective doses commonly range from 0.014 – 0.024 mSv (see table 2).

Who is allowed to operate the i-CAT?

 

State law and/or the state dental board regulate who can take or supervise all dental radiographs, including CBCT.

What are general i-CAT safety features?

 

~ For all new i-CAT installations, a contracted independent radiation physicist firm configures i-CAT installation areas for proper shielding.

 

~ There are both software and hardware safeguards built into every i-CAT to avoid unintended over-exposures.
