Exposure section
Exposure section indicates the period (unit: ㎳) that the detector converts X-rays to image signals. This
value needs to be set longer than the exposure time of X-ray generator to prevent X-rays loss while
converting X-rays to image signals. If you change the time settings, refresh the Post-offset data and generate
new GAIN data to acquire optimized images.
The recommended Exposure section value is 500 ㎳ (Standard).
Pre Exposure section
The Pre Exposure section is allowed to use when delay is occurred until the generator receives EXP-OK
signal from the detector and prepares X-ray generation. Pre Exposure section is set as 0 ㎳ normally,
however, it is recommend to set the actual delay time of generator’s X-ray generation with measurements to
achieve the best performance of the detector. The detector sends EXP_OK signal to the generator, then
transforms X-ray into image signal after the time set in the Pre Exposure section.
EXP OK Delay section
EXP OK Delay section is delay time from when the detector detects exposure request signal (EXP_REQ)
from the X-ray generator to when the detector sends exposure respond signal (EXP_OK) to the X-ray
generator. Some X-ray generators need some time to prepare detecting EXP_OK signal after sending
EXP_REQ signal. This value is determined according to the specifications of X-ray generator. The default
value is 1 ㎳.
