%0 Journal Article %T 3D Cone Beam Volumetric Tomography Dedicated to Maxillofacial Radiology %A Masoud Varshosaz %J Iranian Journal of Radiology %D 2009 %I Tehran University of Medical Sciences %X "nThe 3D cone beam volume/computed tomography (CBVT/CBCT) has been designed for imaging the hard tissues of the maxillofacial region, although it has been used in some era of medical imaging for many years. CBVT is capable of providing a sub-millimeter resolution with the short scanning time of mostly less than 20 seconds and radiation dosages reportedly up to 15 times lower than those of spiral CT scans. In less than a decade, CBVT has revolutionized oral and maxillofacial radiology and is known as the ¡°Standard of Care¡±. Although development was initially directed towards multiplanar viewing for dental implant and orthodontic treatment planning, secondary applications in other areas continue to expand such as maxillo-facial trauma, temporomandibular joint disorders, sinuse pathosis and upper airway evaluation. The intent of this presentation is to provide an overview of CBVT technology, advantages and disadvantages compared to the other modalities such as 2D images and medical CT and examples of justified cases in the oral & maxillofacial region. %U http://journals.tums.ac.ir/PdfMed.aspx?pdf_med=/upload_files/pdf/13051.pdf&manuscript_id=13051
