Cone Beam Volumetric Tomography (CBVT)
CBVT, or Cone Beam Volumetric Tomography is a compact, fast and safe way of acquiring 3D dental imaging. Through the use of a cone shaped x-ray beam, radiation dose and scan time are significantly reduced.
Cone Beam VT provides superior spatial resolution compared to conventional CT for the maxilla and mandible. The radiation dose that is 10–50 times less than the conventional dental CT. The Cone Beam VT scan will provide your practitioner with information that will enable a more accurate and thorough treatment.
Preparing for a Cone Beam VT Scan
Please bring your referral (letter from your doctor/dentist) and your Medicare and/or Pension Health care card with you to your appointment. It is important to bring all previous imaging relating to the region being scanned.
No appointment is necessary. There is no preparation required for the CBVT other than the removal of any jewellery from the head and neck region prior to the scan.
The scan is performed while you are standing. The radiographer will position you and it is important that you remain completely still during the test. You will be asked to rest your chin on a chin rest, bite down onto a small sterile bite piece and hold onto the handle. The machine rotates around your head and takes less than one minute.
Will I feel anything while having my x-ray taken?
No, x-rays are painless.
How much radiation am I getting exposed to?
X-rays are monitored and regulated so you get the minimum amount of radiation exposure needed to produce the image.
Can I have an x-ray if I am pregnant?
An unborn child is more sensitive to the risks of x-rays. Please inform your doctor if you are or you suspect you may be pregnant before having your x-ray.
Can I have a female radiographer/technician to perform the scan?
Yes, please let reception know when making your appointment. We have female radiographers sensitive to the needs of female patients.
Can I accompany my child in the x-ray room?
If your assistance is needed to hold your child still, we will provide you with a lead gown so you can be present in the x-ray room. However, if you are (or suspect you are) pregnant, or if you have other children with you, you will be required to wait outside the room. Babies and small children are more sensitive to x-rays and this will reduce unnecessary exposure. Please bring an additional adult with you to assist if necessary.
Will the radiographer performing my scan tell me what’s wrong?
It is the radiographer’s duty to perform the test and ensure the images are of high quality for the radiologist (specialist) to interpret them.
