What is the difference between a CBCT and a Medical CT Scan?
The main difference between CBCT and Medical(multi-slice)CT are

1.Radiation dose

Region Scanned	CBCT effective dose(sv)ICRP 2007	Medical CT effective dose(sv)ICRP 2007
Mandible	75.3	5003*
Full Head	110.5	1,088.3*

*Average from 3 Scanners(Somaton VolumneZoom 4,Somatom Sensation 16)

2.Image Resolution :

For Hard tissue and teeth,CBCT offers higher resolution and image sharpness compare to medical CT (Medical-Slice CT or MSCT )

3. Metal artifact reduction:

CBCT offers better metal artifact reduction compared to medical CT.This is important because many patients crowns or restorationc that cause streaking artifacts that may interface with the visualization of the region of interest.
