On Friday 27 August at 13.00, Olesya Svystun defends her PhD dissertation entitled "Artefacts in sensor-based cephalograms and the effect of head movement".   

Dentists often request a "cephalogram" (i.e., skull radiograph) from their patients, especially those who demand orthodontic treatment. The acquisition of a cephalogram is a rather long procedure (approximately 15 seconds), making it common that the patient will move during the examination, which may lead to artefacts in the image. This project assessed the prevalence and severity of artefacts in cephalograms and the relationship with head movement. The project generated three studies published in international peer-reviewed journals. The overall conclusion listed in the studies was that the presence of movement and the digital sensor used to acquire the image are directly related to the presence and severity of artefacts in the images. The studies also found that movements caused distortion in the images, an issue that demands further investigation as for its clinical impact.

The summary is written by the PhD student.   

The defence is public and takes place on Zoom. Please read the attached press release for more information.
