While acquiring a tomographic image, the position of patient's head is continuously measured and recorded. For this purpose, several cameras (5) are arranged at the tomograph (1). They measure the position of a reference device (4), which is mounted to the teeth of the patient's upper jaw. Infrared-diodes are arranged on the reference device (4), the position of which is recorded by the cameras (5). This allows to measure the movements of the patient and to compensate for them when generating the tomographic image.
Pendant la constitution de l'image tomographique, la position de la tête du patient est continuellement mesurée et enregistrée. € cette fin, le tomographe (1) est doté de plusieurs caméras (5). Elles mesurent la position d'un dispositif de référence (4) qui est fixé aux dents de la mâchoire supérieure du patient. Des diodes à rayons infrarouges sont placées sur le dispositif de référence (4) dont la position est enregistrée par les caméras (5). Cela permet de mesurer les mouvements du patient et de corriger l'image tomographique générée.
