<unk>  (or<unk> , also referred to as C-arm CT,<unk> <unk>  volume CT, flat panel CT or Digital Volume Tomography (DVT)) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a<unk> .<unk>  has become increasingly important in treatment planning and diagnosis in implant dentistry, ENT, orthopedics, and interventional radiology (IR), among other things. Perhaps because of the increased access to such technology,<unk>  scanners are now finding many uses in dentistry, such as in the fields of oral surgery, endodontics and orthodontics. Integrated<unk>  is also an important tool for patient positioning and verification in image-guided radiation therapy (IGRT). During dental/orthodontic imaging, the<unk>  scanner rotates around the patient's head, obtaining up to nearly 600 distinct images. For interventional radiology, the patient is positioned offset to the table so that the region of interest is centered in the field of view for the<unk> <unk> . A single 200 degree rotation over the region of interest acquires a volumetric data set. The scanning software collects the data and reconstructs it, producing what is termed a digital volume composed of three-dimensional voxels of anatomical data that can then be manipulated and visualized with specialized software.<unk>  shares many similarities with traditional (fan<unk>  CT however there are important differences, particularly for reconstruction.<unk>  has been described as the gold standard for imaging the oral and maxillofacial area.
