I don't know about doing this through code, but I had to do this 
semi-recently.  I used `dcmp2pgm', which I think comes from the OFFIS 
DICOM toolkit ("dcmtk" in my package manager), as well as GraphicsMagick.

I attached a python script I used to convert all DICOMs to PNGs.  It 
will not work out of the box for you, but it is short && should be easy 
to modify.

Moving from there: "dcmdump +P <field>" (or +L?  Both?  I forget) will 
let you pull out an arbitrary DICOM field.  I used this, GraphicsMagick 
again, some scripting, and a little bit of duct tape to create time 
series && annotate each frame with the current time.

HTH,
