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 patientâs head, which is stabilized with a head holder. At certain degree intervals, single projection images, known as âbasisâ images, are acquired.
Ridge Beam vs. Ridge Board. A Ridge Beam and a Ridge Board are both located at the ridge but they serve very different purposes for very different applications. A ridge beam is a structural member used to support the ends of the rafters at the ridge, transferring it's loads to posts or gable end walls. Ridge beams are required by code if the roof slope is less than 3 in 12 (IRC section R802.3).
