Good day,
I hope someone can help me here.
I have a phantom CT image and want to select the objects (Roi). The objects are on a circle. Is there a way to convert this ROI to Cartesian coordinates. many thanks and best regards

Looks like you could simply create a mask using the code in the FAQ:

Why do you need to cut it out (crop it)? That's probably not necessary. If you do you can do this
props = regionprops(mask, 'BoundingBox');
croppedImage = imcrop(grayImage, props.BoundingBox);
