can any tell me how to read a cardiacdicom image and display the image

Can you please clarify what a cardiacdicom image is? Sorry.

Ooh nevermind. I found it here:

http://dicom.nema.org/dicom/workshop-03/pres/solomon-becker.ppt

I'm only familiar with using Python as a web dev language which doesn't seem like the correct application for this use case. Is there a reason why you're tied to Python?

Im not familiar with Dicom networks but I guess you need to investigate their client/server architecture.

Wish I could be more help but your question is very broad and it's unlikely that anyone else here is familiar with writing software for this particular type of health device.
