How about this:

-- snip --
run("Select None");
id = getImageID();
run("Duplicate...", "title=temp");
w = getWidth();
h = getHeight();
makeOval(w/4, h/4, w/2, h/2);
run("Make Inverse");
run("Colors...", "foreground=white");
run("Fill");
setThreshold(2, 25);
run("Colors...", "background=black");
run("Make Binary", "thresholded remaining");
run("Set Measurements...", "center redirect=None decimal=3");
run("Clear Results");
run("Measure");
close();
selectImage(id);
centerX = newArray(1);
centerY = newArray(1);
centerX[0] = getResult("XM", 0);
centerY[0] = getResult("YM", 0);
makeSelection(10, centerX, centerY);
-- snap --
