Which produces a three-dimensional radiographic image?

Cone beam computed tomography creates a true three-dimensional image because it uses a cone-shaped X-ray beam and a rotating detector to collect volumetric data around the patient. That data is reconstructed into a 3D dataset, allowing viewing in axial, coronal, and sagittal planes and even 3D renderings. The other modalities produce two-dimensional representations: panoramic radiography gives a single curved 2D image of the jaws, bitewing shows crowns and contacts in 2D, and periapical shows tooth roots and surrounding bone in a flat projection. These 2D views can have distortion or overlap, whereas cone beam CT provides depth and spatial relationships, making it the method that yields three-dimensional imaging.
