Dental Tomography (3D) X-Ray
Cone Beam Computer Tomography
The cone beam computer tomography (CBCT) is a form of CT scan. A CT, or computer tomography, scan combines rotating x-ray and computer technology to obtain cross-sectional images of the body, or in this case, of the jaw bone and teeth. Typically used for diagnostic purposes, a CT scan is used most often for the diagnosis of cancer as it can show minute differences in soft and hard tissue. It is a non-invasive procedure that can save a patient the trauma of exploratory surgery. A cone beam computer tomography scan uses a cone-shaped x-ray beam to complete the scan in a single rotation as opposed to a regular CT scan that uses a fan-shaped, helical x-ray beam in an arc around the patient.
The Advantages of CBCT
The advantages of a CT scan overall are that they give a much more detailed image of the anatomy that has been scanned. Whereas a normal x-ray just shows bone, and an MRI shows blood vessels and soft tissue, a CT shows a clear 3D image of bone, blood and soft tissue. The cone beam CT scan has an advantage over the normal CT scan as the cone-shaped x-ray beam means that the patient spends less time being exposed to radiation, and the scanner is smaller. The scanning time is typically under a minute, and the radiation dose is under 10 times less than a normal CT scan.
The equipment emits ionising radiation, so this is a consideration of risk to the patient that must be taken into account. However, as above, the risk with cone beam technology is much less than that of a normal CT scan.
