What is CBCT stands for and explain in detail?
Cone-beam computed tomographic (CBCT) imaging is the most significant technologic advance in maxillofacial imaging since the introduction of panoramic radiography. CBCT imaging was initially developed commercially for angiography in the early 1980s. It uses a divergent cone-shaped or pyramid-shaped  source of ionizing radiation and a two-dimensional area detector fixed on a rotating gantry to provide multiple sequential transmission images that are integrated directly, forming volumetric  information.
