Closed kingaza closed 3 years ago

kingaza commented 3 years ago

Hello all,

I would like to train or test my own data by using with the pre-trained model. But I dont' know to generate the ismrmrd header. Could you help me? What kind of information is necessary?

Thanks a lot.

You don't really need to output an ISMRMD header - you just need to write a dataloader that returns the expected information. The SliceData class is pretty large because of boilerplate, but the core part that extracts information from the header is quite small. https://github.com/facebookresearch/fastMRI/blob/1ee19b58daaa15ff7da0c745f766733a2be6c8b0/fastmri/data/mri_data.py#L268-L272

OK. I would like to have a try... If ISMRMD header is generated, I can use the same source code for both dataset from fastMRI and my own, Anyway, thx a lot.
