The dose per area of products delivered by X-MIND prime to the patient during extra-
oral exams is indicated in the graphical user interface.
Note
The dosimetric indications result from the average of dose measures on a lot
of X-rays source assemblies.
The dose is taken at a certain distance from the focal spot of the X-ray source and then
reported to the imaging plane.
To get the DAP value, the dose on the imaging plane is multiplied by the X-ray field area
measured on the imaging sensor that is 50 cm far away from focal spot (the typical size
of the X-ray beam on the imaging sensor is 140 mm x 4.5 mm).
The distance between the focal spot and the patient skin is variable during the X-ray and
on average we can assume the mean distance between the focal spot and the patient
skin as 264 mm.
The overall uncertainty of the indicated value of the air Kerma and dose per area product
is 50%.
Note
As stated in IEC 60601-2-63, no deterministic effects are known with extra-oral
dental X-ray equipment.
