Interacting with images on the canvas

I have this image here:

These are achievements in my game, I would like to give a brief description of each one in the space below when the user taps on the icon, I am using a raycast hit to determine the input however, as they are on the canvas and not in view of my camera, the hit collider does not detect them and so it just hits the panel behind.

Is there a way I can get around this? Making them intractable?
