Quantifying protein bands on SDS gel image?

Is it possible to quantify protein bands on SDS gel from its scanned 
Black/white image? i.e., use a scanner as a densitometry. I know that several
companies (such as BioRad) sell gel image analysis package which are very
expensive. My question is whether I can use the regular scanner like Apple
Scan to estimate relative desnsity of protein bands on the SDS gel. Any
shareware or freeware available?

Thanks in advance!
