* SID : Source to imaging receptor Distance
For larger body types : increase the source current by 25%
For children : reduce the source current (or Exposure time) by 20%
For edentulous patients : reduce the source current by 20%.
The X-ray dose required for image acquisition can vary depending on the X-
ray source and environmental circumstances. You must maintain the
exposure time and change the kVp and mA values according to the signal
level. In addition, if the X-ray source and the distance to the sensor were
changed during the initial installation, the distance (from cone to detector)
must be changed to the 80mm setting.
The exposure time may vary depending on the age, gender and bone
density of the patient.
