You can certainly define a circular region, annulus, etc. using Construct and Compute to create a field with the appropriate geometry. This could be overlaid on the image, the image data could be interpolated on to circular region (i.e., via Map), data could be compared, etc. You could also you Pick or Probe to interactively define points (e.g., one for the center and one to define the endpoint of a radius) in the Image window and then construct a circle.

Hi everyone, I need to select several circular regions of interest on an image, and would like to do so using the visual program editor. Any ideas would be greatly appreciated. Thanks.
