SUMMARY
The discussion focuses on extracting vector components (x, y, z) of pixels from a DICOM image to analyze magnetic field vectors for H1 atoms, specifically with a frequency of 297 and a magnetic field strength (B0) of 3. Participants emphasize that DICOM images represent voxels that can be translated into T1 or T2 parameters, which are stored as integer values multiplied by a scaling factor found in the image header. Additional information regarding the spatial properties of the image is necessary to accurately derive a magnetic field map from pixel values.
