Abstract

Dear Colleagues, This is the fourth issue of Ultrasound International Open (UIO) in 2016. It is a pleasure to inform you that you can now also read UIO online or offline at your convenience on your mobile device (smartphone or tablet PC) using eRef, the new journal app which also includes UIO. This will certainly increase acceptance of this online journal. Just download the eRef app from the Apple Store and register. We are also proud of the increasing number of manuscripts submitted directly to UIO.
