CBCT, abbreviated as "Cone Beam Computed Tomography", is a three-dimensional imaging technique commonly used for imaging examinations in areas such as oral and maxillofacial regions, ear, nose, throat, and craniofacial regions. Compared with traditional X-ray films, CBCT can provide clearer and more detailed imaging information, which helps doctors diagnose patients' conditions and formulate treatment plans.
The working principle of CBCT is to irradiate the patient's body in the form of a conical beam using a rotating X-ray source and detector, and then reconstruct a three-dimensional image through a computer. Compared to traditional CT scans, CBCT can obtain high-resolution images in a relatively short period of time, and the radiation dose is relatively low.
CBCT technology is widely used in the oral and maxillofacial regions, and can be used to examine patients with dental implants, orthodontics, and jaw deformities. In addition, it has certain applications in the fields of otolaryngology and craniofacial surgery.
It should be noted that CBCT still generates a certain amount of radiation during the examination process, so doctors need to weigh its impact on patient health when deciding to conduct CBCT examination. Meanwhile, the results of CBCT examination need to be interpreted and diagnosed by professional doctors to ensure the accuracy and reliability of the results.
