Do you think the fact that the CT scanner at your local hospital needs to be calibrated and computationally reconstructed from X-ray intensities mean it does not result in an "image"?

When we use side-scan sonar to create representations of the ocean floor (e.g. https://commons.wikimedia.org/wiki/File:Laevavrakk_"Aid".png), they are computationally reconstructed from the raw data which are not intrinsically recognized as pixels without reconstruction. Are these not "images"?

What is your actual contention here? Is it that any representation which is not the result of a traditional visible-light camera doesn't count as an "image"?

If so it's an irrelevant distinction to make. If not, you need to articulate in a specific and informed way why the way they reconstructed the image was wrong or could be improved.

It seems from your blog that you don't really understand what a "prior" is and why it might be useful for this kind of signal processing.
