New Mathematics Study Findings Recently Were Reported by Researchers at Yonsei University (Improvement of Metal Artifact Reduction In Dental Cbct Using a Cdte Photon-counting Detector: Simulation Study).

A recent study conducted by researchers at Yonsei University in Wonju, South Korea, explores the improvement of metal artifact reduction in dental cone-beam computed tomography (CBCT) using a Cdte photon-counting detector. Metal artifacts, such as streaks and shadows, can degrade the image quality of CBCT scans when patients have metal implants or prostheses. The study proposes a new metal artifact reduction (MAR) method called the high-energy trace normalized-MAR (HT-NMAR) algorithm, which utilizes a photon-counting detector to enhance image quality. The simulation study demonstrates that the proposed MAR method effectively reduces metal artifacts in CBCT scans without any contrast anomalies. [Extracted from the article]
