I am starting to look at the brain data, and I noticed that the reconstruction size is not as formatted as for the knee data, it’s not always 320 x 320.
I thought that I could obtain the information of the expected reconstruction size using the ismrmrd header, more specifically the
encoding.reconSpace.matrixSize, but it doesn’t seem to match the actual reconstruction size found in
'reconstruction_rss'. An example of this mismatch is for example the validation file
In this file, the kspace has a shape of
(16, 4, 512, 213), the reconstruction has a shape of
(16, 213, 213) and the encoding reconstruction space has a shape of
For the train and validation datasets it’s of course not a problem because you can always get the reconstruction size from the actual reconstruction but for the test dataset (and probably the challenge dataset), I don’t know how to proceed.
How can I know the expected reconstruction size from a test file?
