I used the code in this message,
http://www.mail-archive.com/numpy-discussion@scipy.org/msg15642.html .
I don't know if it's correct or not.

Two other arguments in the imread function would be helpful, roi and
band. 'roi' is a 2 or 3 element tuple of coordinates to read, which is
useful when reading from a very large image.
