28 Image System Calibration
IMAGE INTENSIFIER ELECTRONIC CENTER
1. In the AUTO FLUORO mode, take a MAG 2 exposure. Mark the monitor at the
center of the Beam Alignment Tool pattern.
2. Make a NORMAL field exposure and mark the monitor at the center of the Beam
Alignment Tool pattern.
3. While making a NORMAL field exposure, use the target on the beam alignment tool
to measure the distance between the MAG 2 and NORMAL marks. Verify the
distance is less than or equal to 9 mm.
NOTE: Note that each ring on the target is 1 mm wide with a 1 mm space between
rings.
4 Make a mark on the monitor midway between the MAG 2 and NORMAL points. The
point marked is the “average electronic center”.
5. Make a NORMAL field exposure. Re-adjust the Beam Alignment Mask X and Y
screws until the image is centered on the average electronic center (marked in the
previous step).
6. Leave the Beam Alignment Mask in this position for the remainder of the Beam
Alignment procedure.
