摘要:
A calibrator is provided for carrying out a calibration of an investigation device, which has means for the generation of an excitation radiation, which is to be directed at a tooth tissue region to be investigated, a radiation detector and radiation evaluation for the detection and evaluation of a response radiation arising from the irradiated tooth tissue region in response to the irradiation, and a radiation transmission for the transmission of the excitation radiation and the response radiation, which includes at least a diagnosis probe for directing the excitation radiation at the tooth tissue region to be investigated and for detecting the response radiation, has a reference element, which for carrying out a calibration of the investigation device is to be irradiated by this device via the diagnosis probe. In accordance with the invention the calibrator has a repository via which the diagnosis probe is held in a defined position and/or orientation with regard to the reference element.
摘要:
A dental system may transilluminate teeth using a light source for producing examination radiation by directing the examination radiation at a tooth to be examined. An optical image of the tooth illuminated by the examination radiation may be acquired. The light source may include a light-guiding and/or light-deflecting element that faces the tooth to be examined. Light-guiding and/or light-deflecting elements may be embedded in a transparent, flexible coupling body that is provided to rest on the tooth or the gingiva of the tooth.
