What is cone-beam CT?

Cone-beam computed tomography (CBCT) is a medical imaging technique consisting of X-ray computed tomography in which the X-rays are divergent, forming a cone. CBCT is primarily used when standard medical CT is not suitable, especially in dentistry, where it provides high-resolution three-dimensional images of the teeth, bone, and surrounding structures with lower radiation exposure compared to traditional CT scans. It is also used in other medical fields like orthopedics, otolaryngology, and interventional radiology.
