CBCT Overview
Technical Description of CBCT
Main article: Technical Description of CBCT
This page shows the working behind the CBCT technique, and shows the step-by-step process of image acquisition, reconstruction, visualization and manipulation.
Descriptions of the Dental clinical uses of CBCT
Main article: Dental uses of CBCT
The various uses of CBCT within Dentistry.
Radiation Issues
Radiation doses and risks of CBCT
Main article: Radiation Doses and Risks of CBCT
As an X-ray imaging modality, CBCT examinations result in a certain dose uptake for the patient. This radiation dose is variable, affected by a number of factors.
A strategy for Radiation Protection of patients
Main article: CBCT Radiation Protection for Patients
An important aspect of optimisation of dental CBCT use, is to lower the patients dose uptake as much as possible, using different strategies.
A strategy for Radiation Protection of staff
Main article: CBCT Radiation Protection for Staff
Personnel dose is strictly regulated by most national councils. Operators of CBCT devices should be protected against scattered radiation.
Dose Maps for CBCT
Main article: CBCT dose maps
Creating dose maps, depicting the amount of scattered radiation at various locations in the vicinity of the CBCT device, plays an important part in the protection of personnel.
Quality Control
A Quality Assurance Programme for users of CBCT
Main article: CBCT Quality Assurance Plan
The Quality Assurance process is vital in order to provide confidence in the suitability of an imaging technique for its intended purpose and to ensure its safe use in clinical use. It is usually performed by using a test phantom in conjuction with software routines that help in the interpretation of the results.
Information about Quality Control Test Tools for CBCT
Main article: CBCT Quality Control Test Tools
The use of a specifically designed phantom, with a size and densities resembling those of dental interest is necessary. A variety of test objects shall be included in the phantom body (as inserts) for the testing of the imaging performance characteristics, such as High Contrast Resolution, Low Contrast Resolution, Geometric Accuracy, Spatial Resolution and others. A software tool may be used for the automated analysis of the phantom imaging results and the evaluation of image quality.
Evidence-based Referral / Selection Criteria for CBCT
Main article: Evidence Based Referral (Selection) Criteria for CBCT
Referral (or selection) criteria are a type of clinical guideline, designed to help in the process of justification of an X-ray examination. This section contains a detailed description of these guidelines.
