I have been trying to turn the HitTest property off for an imrect object, such that I can click on objects behind it. However, a simple "set(imrectHan,'HitTest','off');" does not do the trick. Does anyone know how to solve this?

The imrect is built from low-level lines and patches so turn the imrect's Children's 'HitTest' off.
h = imrect
set(get(h,'Children'),'HitTest','off')

What if you inverse the order of Children in your axes? Basically you would send the rectangle at the "back" of the current axis so you could play around with other elements. When you're done you can switch back. It might not be perfect but I think it would work; from the Matlab doc imrect does not have a HitTest property so maybe that's why using it does not work.
Example code to flip the order of the axes children:
set(gca,'children',flipud(get(gca,'children')))
Thanks to Matt Fig who provided the idea here
I tried with a simple code and 2 rectangles and it worked well.

Yep! I learned something with Sean's answer ; I did not know the trick to get the Children of imrect that's nice.

NOTE: I created an image in a UIAxes using imagesc:
app.My_image_handle = imagesc(app.UWBAxes, app.UWBdata);
In that case I do NOT set the HitTest property of children of the image handle. Rather I set it directly on the image handle:
set(app.My_image_handle,'HitTest','off')
