If you repeatedly erode & dilate (imerode & imdilate) the image you should get close to what you want if you use the right "neighbourhoods".
You could alternatively generate ANOTHER binary image, which is 1 (true) where you want to keep it, and 0 where you want to discard it. You'll need to think about how you generate that image, but for a simple version:
other_binary_image = false(size(im));
other_binary_image(:,1:50) = true; % to keep the left 50 columns
new_image = im & other_binary_image;
You'll need to think about how you generate this "mask" to make sure it does what you want it to.

Yes, that's one way. lain is probably thinking of the method of alternating sequential filters. Here is the reference: http://www.esiee.fr/~coupriem/Pdf/cb04.pdf It looks like (from what the new perimeter looks like) the method you used was watershed.
