Dental hardware radiology

Objective: Artifacts from dental hardware affect image quality and the visualization of lesions in the oral cavity and oropharynx in computed tomography (CT)

Therefore, magnetic resonance imaging is considered the imaging modality of choice in this region

Various manufacturers introduced their newly developed digital dental radiographic systems

Among those, Ulf Welander presented Sens-A-Ray, on behalf of Regam Medical Systems, showing intraoral images obtained with a new full-area CCD sensor that directly converted X-rays into charges in the silicon substrate

Taking into account the modest X-ray flux from a dental radiographic source, the inherent inefficiencies and losses in the optical chain, and the approximately 20 ms time window for each frame, it was to be expected that the image signal-noise-ratio would be awfully poor, which was in fact the case
