Inquiry about Determination of 'max' and 'norm' Values for Each Patient #3
Description
Hi,
I'm seeking clarification on the process of determining the 'max' and 'norm' values for NYU patients. These values are crucial for intensity scaling during data analysis. Understanding their origins is pivotal to ensure accurate results.
We've attempted to calculate these values independently, but they don't match the values present in the h5 attributes.
While our code reads the 'max' and 'norm' values from the h5 file, it currently doesn't use them. However, an RIM reconstruction model relies on these values for intensity scaling.
This code reads in the max and norm value, but is not used further. However, an RIM reconstruction model uses these values for intensity scaling.
with h5py.File(fname, "r") as hf:
kspace = hf["kspace"][:]
calibration_data = hf["calibration_data"][:]
hdr = hf["ismrmrd_header"][()]
im_recon = hf["reconstruction_rss"][:]
atts = dict()
atts['max'] = hf.attrs['max']
atts['norm'] = hf.attrs['norm']
atts['patient_id'] = hf.attrs['patient_id']
atts['acquisition'] = hf.attrs['acquisition']
Your insights into this matter are greatly appreciated. Looking forward to your response.
