JoeGuru ,

Extremely well done

When the other app went exorbitant, switched to this one and never looked back.



Images look great. Scrolling on thin sections on CTs was a little slow even on fast srolling setting. A scroll bar would be nice. There is no progress bar that I could find when retrieving studies so it feels unresponsive when retrieving studies with many images.

Excellent mobile PACS viewer

Used in conjunction with Horos on a mac server. A handy program to quickly review imaging studies.
