Hi,
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 file_brain_AXFLAIR_203_6000881.h5
.
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 (512, 408)
.
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?
