    One of the biggest problems of many systems for me, is that there is too many ways to manipulate data and more detail than necessary becomes required input. I'm not being specific to photography but the logic applies there too.
    My dentist converted to digital Xray... and he diagnosed a cracked tooth that he wouldn't have been able to with film due to the cool software manipulations. What's more, he could email the digital images (xray and intraoral digital pictures) to the insurance compnay for approval... making it possible to fix the problem before it got to a bigger problem. So what is the "needed threshold"? I totally agree, though, that sometimes the obvious threshold is exceeded just because it can be done. This is not the case with digital dentistry in my opinion, though. Digital dentistry seems to increase the quality of health care.

    Luckilly, we don't have to bother with that nonsense!

    ... so can they do software "enhancements" to that scanned image?

    Steve.
    There are people alive because of the advances in X-rays due to it going digital. You can be against progress all you want, but the time may come when you will quickly backpedal and demand a digital image so that your doctor has the best information available.

    I also feel tempted to post a very famous X-ray which was certainly taken during the analogue age. Very famous.

    The digital X-ray, MRI and CT's are often printed onto traditional X-ray etc films for archival reasons. The workflow is often digital pictures > view on screen and enhancement > optical printer onto analogue film. A small dentist can't always afford this workflow big Hospitals, aircraft manufacturers etc... can and do.

    I would not step foot in any doctor or dentist office that didnt use the most modern technology to care for their patients. Hell, we pay enough for it.
    My experience is the digital 'enhancements' produce more artifact and false-positive findings.
    Conclusion from the following paper: "Observer enhanced Sidexis [digital dental] images exhibited a statistically significant lower diagnostic accuracy than the film images."

    2005??? Why not find something more recent? Or has digital gotten better?
