Images extracted from one CBCT Scan (excluding the photographs)
FOV Field of View Are options that allows us to choose the best x-ray beam size/ratio for a study.
We can isolate an area from 8cm x 8cm to as large as 23cm x 17cm. We can customize the field as well.
Voxel: We also can choose the voxel size of the scan. Voxel derives from the terms combine from Pixel and Volume. The best depiction that I can give you is a rubics cube.
The smaller the cube the higher definition of the scan. Our average scan we take is at a .25mm voxel. This allows us to make cross-sectional slicings down to .25 mm, and we typically will measure and print at 1mm. (depending on the study ordered).
What is CBCT- Cone Beam Computer Tomography?
CBCT is a digital x-ray scanner specifically designed for scanning the head and jaws. The scanner rotates 360 degrees around the patient's head in a matter of seconds. The x-ray is a low energy fixed anode tube similarly used in panoramic machines. This method reduces radiation scatter common to most conventional x-rays. The cone shaped x-ray provides 360 views that can be presented in 2D image and 3D volume for advanced planning and diagnostic support.
[Why the need for a CBCT?]
This one scan provides more images than plain film conventional imaging, with complete visualization of the patient's entire maxillofacial region. These images clearly display TM disorders, impacted teeth, critical bone and tooth relationships, oral- nasal airways, para-nasal sinus, mandibular canal and difficult to see pathologies within one volume. The user friendly software system reconstructs true size, distortion free, high resolution images.
[Why is this better for patients?]
The CBCT scanner is fast, comfortable (nothing goes in the mouth), and painless for patients. It provides a complete set of maxillofacial images with less radiation than conventional orthodontic and medical type CT work-ups. CBCT now can re-create true size cephalometric and panoramic images, virtually eliminating the need for conventional orthodontic x-rays, so your patients will be comforted by the knowledge that you have all the information needed to evaluate and plan their treatment.
