PROBLEM TO BE SOLVED: To provide methods, systems and devices for determining characteristics of an intraoral dental imaging sensor.SOLUTION: A method includes providing an intraoral dental imaging sensor 430 having a housing 419 and a magnetic field sensor disposed in or on the housing 419, placing the intraoral dental imaging sensor 430 in a holder 433, positioning the intraoral dental imaging sensor 430 and at least part of the holder in a mouth of a patient, attaching a reference magnet 435 to the patient, receiving, by an electronic processor, magnetic field data from the magnetic field sensor, determining, by the electronic processor, information including a position of the intraoral dental imaging sensor 430 in the mouth of the patient on the basis at least partly of the magnetic field data, and detecting x-rays by the intraoral dental imaging sensor 430 to produce image data.SELECTED DRAWING: Figure 18 |
