Digital Imaging

Computerized scanning technology has been in use for over 30 years. Originally , it was called Computerized Axial Tomography or CAT. Hospital based CAT scanners were radiation intensive, supine gantry style units which require large suites in radiology centers. The computer itself would take the space of an entire room. Except for the occasional trauma or involved pathology patient, dentists really did not utilize CAT scan technology.

Today with advances in miniaturization and computer software and a revolution in imaging, CAT scan technology has moved from the hospital to the private dental office.

Dentists nowadays need to become familiar with terms such as scan height, slice thickness and scan diameter. Many important concepts unique to CBCT are: radiatiopn dosage, volume averaging, voxel size, attenuation, Hounsfield units, orthogonal reconstructions, surface rendering, multiplaner reconstructions, axial corrected temporomandibular joint sagittal and coronal tomography, DICOM format, 3-DVR, stereolithographics and data portability.
