What kind of displays are used on current workstations? The iPhone has excellent color fidelity and gamut. Or is it an issue of screen size? Do the workstations have hoods and hardware calibration? (I don't know much about radiology, but in another life I worked in print production on CRT monitors, so I know a bit about display calibration). I find it hard to imagine any responsible radiologist doing a diagnostic interpretation on a cervical spine fracture xray from viewing it on an iPhone. I suppose if you are desperate, then sure, you do what you can. At the very least, they will love it for the consultation potential. I am sure my team will hear about this on Monday morning, first thing...:)
Not approved for high res imaging. But I agree with you that most radiologists will be reading from monitors that cost 10 times what an Ipad cost and are DICOM gray scale compliant.
