what is a cone beam
Cone beam computed tomography. Cone beam computed tomography. MeSH. Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, or flat panel CT) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone.
Advanced Cone Beam CT Technology. CBCT scanners, on the other hand, are based on volumetric tomography, using a 2D extended digital array providing an area detector. This is combined with a 3D x-ray beam (Fig. 1b). The cone-beam technique involves a single 360Â° scan in which the x-ray source and a reciprocating area detector synchronously move around the patientâs head, which is stabilized with a head holder. At certain degree intervals, single projection images, known as âbasisâ images, are acquired.
