Computerized tomography is an imaging technique that is used to see inside the body without making incisions. However, CT scans can have some limitations for patients who may be exposed to high radiation doses when undergoing it. Consequently, digital cone-beam computer tomography (CBCT dental scan) has been introduced as an alternative imaging technique in which a narrow beam of X-rays is used to scan the area of interest from many directions. The scattered X-ray photons are detected by a matrix of dozens of small photodetectors, called focal plane array (FPA). The information from these detectors is processed by a computer … Continue reading What is the Contraindication of CBCT?
