The continuing evolution of iOS devices, particularly the iPad, as medical tools took a historic step forward as the US Federal Food and Drug Administration (FDA) approved Mobile MIM from MIM Software as the first mobile radiology app for viewing images and making medical diagnoses. While not intended to replace institutional workstations, it allows doctors to view CT, MRI and PET (et al) scans when there is no access to a workstation and without waiting for film. With the FDA's 510(k) clearance, the app should be available in the US App Store within a week.
