FYI, RawImageGuess module can now also load 4D movies from Samsung MVL files - see example here:

> [@Samsung SonoAce 4D ultrasound mvl file loading](https://discourse.slicer.org/t/sonoace-dicom-files-loading-error/12452/12):

> I’ve also found a 4D sequence in the file (you can read it with [Movie4D.seq.nhdr](https://1drv.ms/u/s!Arm_AFxB9yqHu70Ow3KQa3Lt5hNJIQ?e=z0tLjv) header): [SlicerCapture]
