From the Osirix example set: GRUSELAMBIX/LHC/LHC
Set has 14 images, but show no 3D visualization when loaded into MIRROR4ALL
Looking at DICOM images 1 at a time with Osirix Lite, they do not appear to form slices of a coherent 3D object. So issue is that perhaps the MIRROR4ALL can detect that they do not form a 3D data set and give an understandable error message when loaded into browser.
