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.

Overview

At Norwest Medical Imaging, 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 films relating to the region being imaged.

No appointment is necessary. There is no other preparation required for the CBVT other than the removal of any jewellery from the head and neck region prior to the scan.

Scanning

The scan is performed while you are standing. The radiographer will position you as required, and ask you to stay very still. 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 handles to ensure no movement whilst the machine rotates around your head.

The scan itself takes less than 1 minute.

Results

Your images and report can be available on the same day for collection. They can also be provided on CD or electronic transfer to your referring practitioner if requested. Norwest Medical Imaging strongly advises that you return to your referring dentist or doctor, in order for your doctor to discuss your CBVT report with you.

FAQs

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 exposed 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. Instead, please bring an additional adult with you to assist.

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 doctor) to interpret them.
