(3) Measuring with a tentative Pre Delay
When the Phase2 button is selected, Pre Delay = 0, Post Delay = 255 is automatically set
internally.
A-1) Set the X-ray generator to the following imaging conditions.
[Imaging conditions] X-ray tube voltage: 100 kV
X-ray tube current: 50 mA
Irradiation time: Value close to the value obtained in Phase1
(180 or 200 msec in the example in B-5)
Focal distance: Align with the grid used.
Phototimer: Disabled (OFF)
A-2) Only mAs will be displayed according to the X-ray generator being used. In this case, set
the exposure conditions as follows.
[Imaging conditions] X-ray tube voltage: 100 kV
X-ray tube current: 50 mA
mAs: Set the mAs vale between 2.0mAs and
4.0mAs
Focal distance: Align with the grid used.
Phototimer: Disabled (OFF)
B) Select the [Phase2] button and select the [Execute] button like Phase1 to set the sensors to
READY status. Then press the [Expose] button on the X-ray generator to irradiate
X-rays.
After 10 irradiations in Phase2, [Pre Delay time] and [Post Delay time] are automatically
calculated and displayed.
(The Phase2 measurement results are saved in the [phase2.ers] file.)
