I'm not sure what you mean... do you want to get the indices of the
pixels which are set to 1 in your mask image? Then have a look at the
WHERE() function.

For example, instead of

new_img = original_img * mask_img

you can do it that way:

index = where( mask_img eq 1 )
new_img = 0 * original_img
new_img[index] = original_img[index]

or:

index = where( mask_img eq 0 )
new_img = original_img
new_img[index] = 0
