How to warp/stretch a sector/"pie slice" into a whole circle

[Onnij]

I have a image that is shaped like a 90° "pie slice" ergo a sector. I need to stretch/warp it so that it forms a complete circle in a way that the two sides of the sector meet. I can't duplicate the image to form a circle because I need the content to be warped in a radial form.

I attached a photo trying to depict my goal. 

Is this possible in Illustrator? Warping tool? I already tried it but it seems to be designed for rectancular images.

I have to latest version of Illustrator.

I usually only use Photoshop, so if you know how to do this in Illustrator I might need a bit more detailed guide. And if this is possible in Photoshop I'm happy to hear about it too.

Not as such. Can you show the actual image though? It may be possible to achieve what you want via other means.

Good to know. I was suspecting that because I didn't find any posts about this from anywhere.

The image is a ultrasound monitor image such as the one on the link below. I would need it to stretch in to a circle/disc. It is only the sector shaped image in the middle, not the other technical stuff.

It might be possible - with an artbrush ...

The artbrush that pixxxelschubser mentioned could give you this. But the starter image would no be a pie, has to be a rectangle.

Okay, thanks! That is the closest example so far to what I am trying to achieve.

Maybe I could first try to convert the sector form into a rectangle (or near that and crop it) and then go from there? 

Do any of you have an idea then how to get from pie piece into a (near) rectacle? Free forming with anchor points?

Please show a concrete example

Onnij,

What you wish is the opposite of what is usual/easy/possible to do, a bit like the UnBlur filter that is joked about in Photoshop.

This could be called an UnArch effect.

Especially the pie slice with its single point at the bottom, which is supposed to be stretched to the same length as the quarter circle at the top, is a tough task.

I believe a better approach would be to perceive which horizontal (set(s) of) shape(s) can be made to look right when stretched and bent to fill a full (circular) ring; and forget about anything extending to the centre, or even near it.

Depending on the actual artwork, maybe working in different ways at different distances from the centre, as in separate concentric rings with different (moderately varying) levels of stretching and bending, going from more stretching and less bending in the outermost ring to the opposite in the innermost one.
