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.
To reduce an initial measuring error, you should use a 4mm Al filter to
maintain a distance that is identical to the conditional circumstances of the
The exposure time may vary depending on the age, gender and bone
