Current Evidence on the Image Quality and Diagnostic Effectiveness of Metal Artefact Reduction Algorithms in Dental CBCT: An Overview | Chapter 5 | Medical Science: Updates and Prospects Vol. 2

 

Dental cone-beam computed tomography (CBCT) has significantly enhanced diagnostic capabilities in maxillofacial imaging, offering high-resolution, three-dimensional views with relatively low radiation exposure. Compared with computed tomography, CBCT generally delivers a lower radiation dose when producing images for equivalent diagnostic objectives. However, the presence of metallic objects such as implants, restorations, and orthodontic appliances often introduces image-degrading artefacts that compromise diagnostic accuracy. Various metal artefact reduction (MAR) algorithms have been developed to counteract these limitations. In recent years, various post-processing methods have been developed to minimize the impact of metal artefacts in CBCT. Despite these advances, the clinical effectiveness of MAR in dental CBCT remains unclear. Most existing studies are in vitro, relying on phantoms or extracted specimens under controlled conditions that do not fully replicate the complexity of in vivo imaging. There is a critical need for well-designed clinical studies which can determine when and how MAR algorithms truly enhance diagnostic outcomes in different dental applications. This review synthesizes current evidence on the diagnostic effectiveness of MAR algorithms in dental CBCT, emphasizing their methodological principles, clinical outcomes, and limitations across different imaging contexts.

Accommodation Mechanism of the Human Eye and the Autofocus System Based on Craig’s Effect| Chapter 3 | New Frontiers in Physical Science Research Vol. 5

 It is famous that Craig’s effect in a wide-area photoconductive container with long photoconductivity and a non-linear light characteristic makes likely to estimate the quality of the countenance formed on its delicate area. We suggest that the human retina everything in the same way as the photoconductive container. The suggestion makes attainable to deduce from the physical laws of visual idea the mathematical formulas for objective estimation of the concept quality seen by the human, on the one help, and better understand whole of the human eye accommodation mechanism all along monocular observation, in another way.
