Get current sprite from filled Image PRESERVING ITS TRANSPARENCY

Hi!

I asked this question on StackOverflow but did not get any answers. I hope here I will be able to find someone who can help to resolve the issue :)

The explanation is pretty simple, I have a UI Image on my scene, its type is set to Filled (Radial 360). What I need is to get/create a sprite that would be exactly the same as the current one on this Image, meaning that it would be just a piece of the original sprite (like a piece of pizza). I provide two screenshots to clarify the issue.

Thank you for taking the time to read through my post and I am waiting for your help!
