I typically see the dicom header PhaseEncodingDirection with Siemens data; however, I've noticed the dicom header PhaseEncodingAxis with GE data and was wondering if these values are identical and are simply labelled different due to their respective scanner, or if they represent different values? I ask because I use the PhaseEncodingDirection value to determine the BIDS _dir- label (i.e. if PhaseEncodingDirection == j and orientation == LAS, then dir = PA). I was wondering if this logic also applies to PhaseEncodingAxis values?
