Abstract
A calibration unit for the calibration of a macroscopic medical imaging device. The calibration unit is especially suitable for the calibration of a macroscopic dental imaging device. The calibration unit comprises a main body having a front surface being configured for being optically oriented towards the imaging device. Moreover, a fluorescent material of a first type is arranged in a first sector of the main body. Furthermore, a fluorescent material of a second type is arranged in a second sector of the main body. Alternatively or additionally to the fluorescent material of the second type, an opaque, non-fluorescent material is arranged in a third sector of the main body. Additionally, a macroscopic medical imaging calibration system, especially a macroscopic dental imaging calibration system is presented. Moreover, a use of the calibration unit as described above for the calibration of a macroscopic medical imaging device, especially for the calibration of a macroscopic dental imaging device, is explained.
