According to the technical data provided by the Artec Group the scanner is small (261.5 mm Г— 158.2 mm Г— 63.7 mm) and lightweight (800 g). None of them underwent facial surgery, were suffering severe facial malformation or were afflicted with a seizure disorder triggered by flashing lights.ДЄrtec EVA В® is a mobile three-dimensional scanning device. After institutional approval of the Ethics Committee of University Hospital RWTH Aachen, Aachen, Germany (EK 168/16), written informed consent was obtained from a group of 28 volunteers consisting of 16 females and 12 males. The study was conducted according to the declaration of Helsinki. The aim is to evaluate if investing in two scanners and setting up a bundle for scanning results in significantly more precise scans. In this study, the accuracy achieved by two coupled Artec EVA В® scanners against the accuracy achieved by a FaceScan3D В® is compared. Until now, it has been used in the technical environment. The other device, Artec EVA В® (Artec Group, Luxembourg, Luxembourg), has not been used for medical purposes that often. FaceScan3D В® (3D-Shape GmbH, Erlangen, Germany) is already commonly used in literature. For this study, we have chosen two optical three-dimensional scanners using structured light. Even if it is possible to capture the face with some devices, there are few literature reviews to evaluate their accuracy. The face consists of different complicated and fine geometric structures. Receiving exact three-dimensional surface data of the human face is not trivial. Recently, three-dimensional data of the human face have been increasingly used. All of them say that their product leads to the best result. To increase their share of the market, manufacturers develop new features that should make their devices more attractive. Currently, numerous devices are available in the market and are used in medicine. Another alternative is using a laser scanner or a scanner that uses structured light for capturing its data. Even this technique comes with the disadvantage of touching the patient. For receiving three-dimensional data from the outer surface of the patients, coordinate measuring machines have been used. Major disadvantages are the limited availability, high costs, and in the case of CT, a lot of ionizing radiation. Using a computed tomography (CT) or magnetic resonance imaging scanner results in detailed three-dimensional data from the inside and the outside of the patient. At present there are different techniques for acquiring the three-dimensional data available in the market. These data can be used for different purposes such as planning for surgical treatment, visualizing complex procedures for the patient or comparing the patientвЂ™s outcome after treatment. A common one is capturing three-dimensional surface data of patients. Today, numerous new technological methods are used in medicine.
