Hi,
\nI stumbled upon this multi-frames dicom case (SeriesUID 1.2.826.0.1.3680043.8.498.99804081131933373817667779922320327920) with metadata ImageOrientationPatient [1, 0, 0, 0, 1, 0] and ImagePositionPatient varying in z.
\nThus, I'm expecting the image to be axial but looking at the frames it is coronal. Are the orientation/position metadata unreliable for multi-frames dicoms?

This reflects real world data. Its unfortunate, but this is how we received the data from a real clinical site.
