Non-Perpendicular Angles - AGFA DR 600 User Manual

Non-perpendicular angles

If the X-ray tube is not perpendicular to the bucky of the wall stand, the AEC
fields that are drawn on the front panel of the bucky will not coincide with the
AEC fields visualized on the camera image. The AEC fields visualized on the
camera image represent more accurately the position of the actual AEC field
inside the bucky.

Figure 58: X-ray tube not perpendicular to the bucky
The visualization of the collimation area and the AEC fields is virtually
projected on the patient's body. The camera is positioned at an offset from the
X-ray focal spot. This is the reason why the visualization may be warped.
