Description :

When compared with medical ct cbct has increased accuracy higher resolution reduced scan time a reduction in radiation dose and reduced cost for the patient this book gives an overview about cbct and its applications advantages and limitations in dentistry. The introduction of cone beam computed tomography cbct devices changed the way oral and maxillofacial radiology is practiced cbct was embraced into the dental settings very rapidly due to its compact size low cost low ionizing radiation exposure when compared to medical computed tomography. Cone beam computed tomography cbct cbct is a medical imaging technique consisting of x ray computed tomography ct where the x rays are divergent forming a cone not thin or fan shaped such as that used in typical medical ct units. Overview cone beam computed tomography cbct scans generate multiple projections that are immediately processed into 3 d images the images can be transferred online or sent on cd along with the radiology report the clinic is open to the public. Cbct in dentomaxillofacial radiology is a generic term applicable to a broad range of cbct machines and features experimental outcomes and literature statements regarding radiation doses imaging performance and diagnostic applicability of dental cbct cannot be simply transferred from one cbct model to another considering a wide variation in technical characteristics and clinical diagnostic
