CBCT

Cone Beam Computed Tomography

CBCT is an imaging modality which lets us get a 3D, 360 degree view of your anatomy at the upper neck.  This is essential to making sure that we provide the best possible adjustment for you.  

Most people have some asymmetry in their bones when comparing the right side to the left.  Your left joint may be angled at 27 degrees, but the right joint may be angled at 45 degrees.  That difference from side to side will change how we adjust you.

This technology also allows us to break down your image into smaller slices, which give us a view similar to an xray, but without all the overlapping anatomy.  This allows us to clearly see where those top two bones have moved, and to calculate a precise adjustment for you and your anatomy.

How do we use CBCT?

The following images are examples of what a misalignment looks like in the upper neck, as well as some special issues that we have seen, and work with, in our office. 

What a C1 Misalignment looks like

The Blair technique looks at how C1 is sitting underneath the Occiput.  Is it forward, backward, or perfectly in line?  The right and left sides of C1 can move independently, which means, often there is more than one misalignment at this bone.  These two images were from the same patient, and you can see that there are two misalignments - one on the right, and one on the left.  This is easily managed in our office.

What a C2 misalignment looks like

C2 has its own unique movement, which means that it can misalign independently of C1.  When C2 misaligns, we're looking to see where it is located in relation to C3.  We look at both the right and left sides of the joint to see how this bone has moved.  Just like at C1, each side can move forward, backward, or a combination of the two.  Often, C2 has misaligned on both sides, especially in patients who have had significant trauma, such as a car accident, concussion, etc.
