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:
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.
Various python packages handling dicom images can be found in the Python Package Index https://pypi.python.org/pypi?%3Aaction=search&term=dicom . I don't know them, so I suggest you test them and evaluate them :)
I would start with pydicom for example.
