Appendix

A.1 X-ray Exposure Guide

The required X-ray dose for the best image is dependent on the following:

- X-ray source (tube assembly, manufacturer, AC/DC, etc.)

- Distance between beam focus and sensor

- Tooth (object) to be X-rayed

- Bone density and age of patient

- Miscellaneous circumstances, etc.

The X-ray dose influences image quality. Based on fundamental laws of physics, an insufficient
dose generally means higher image noise, which leads to poor detail discrimination. On the
other hand, an excessively high dose can cause the sensor to be overexposed. This is also
perceptible by a decrease in detail discrimination, specifically in darker areas.

The effect of image processing reduces the difference between image qualities of different
doses. Users can adjust brightness and contrast in the option menu.

The recommended exposure dose is from 300µGy to 600µGy when measuring without an
object. Exposure time corresponding to the dose may vary depending on the X-ray equipment
used. Recommended exposure times according to positions are as shown on the Exposure
Time Table.

The X-ray dose is maintained through tube voltage (kVp) and current (mA), as well as exposure
time according to the signal level.

Since the exposure time depends on the diagnostic problem as well as the
clinical situation, the selection of an adjustment is the responsibility of the
treating physician.

Image degradations caused by overexposure of the sensor cannot be
compensated, but an insufficient dose can be partially compensated
through image processing.

*Recommendation on Exposure Time is limited to Intra Oral X-ray Unit in the above table

For larger body types : increase the source current by 25%
For children(5~21age) : reduce the source current (or Exposure time)

by 20%

For edentulous patients : reduce the source current by 20%.

Since the X-ray exposure condition can be changed depending on the age,
gender and bone density of the patient, in case of Pediatric, X-ray exposure
condition can be changed by expert’s judge.
For further information, please refer to FDA Pediatric X-ray Imaging
webpage,

http://www.fda.gov/radiation­emittingproducts/radiationemittingproductsandprocedures/medicalimaging/ucm298899.htm)

The X-ray dose required for image acquisition can vary depending on the X­ray 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.
