I just found out there is a "NaN background" command which does the  
trick after setting the threshold. Just in case anyone else needs to  
do this in the future, here's the short macro commands that does what  
I was describing:

selectWindow("Image");
setThreshold(0.00, 0.65);
run("NaN Background");
resetThreshold();
