6.11.1.3 Incorrect film contrast and density<br />
• <strong>Image</strong>s too clear<br />
Normally this indicates that the exposure parameters are too low<br />
with respect to the patient size. Another possible cause is a wrong<br />
film development process, especially if a manual developer is used.<br />
Another possibility is the misalignment of the X-ray beam with<br />
respect to the alignment of the two collimators.<br />
Remedy:<br />
– Increase the exposure parameters<br />
– Check the development process (liquids, temperatures, duration,<br />
etc.)<br />
– Check that the panoramic cassette holder is fully closed in<br />
panoramic position (check that it is really fully pushed against<br />
the mechanical stop)<br />
• <strong>Image</strong>s too dark<br />
Possible cause:<br />
Exposure parameters too high with respect to the patient size.<br />
Remedy:<br />
– Decrease the exposure parameters<br />
– Check that the development process (liquids, temperatures,<br />
duration, etc.).<br />
• <strong>Image</strong> without contrast (flat image)<br />
In the case the film has a poor contrast (flat image), there can be<br />
different causes.<br />
Possible cause<br />
kV value too high<br />
Improper film-screen combination<br />
Edge of the film (non-exposed area)<br />
blurred<br />
Remedy<br />
Decrease the kV value<br />
Check film-screen compatibility<br />
Check the film (expiration date,<br />
storage)<br />
