Those who want to use Horos or OsiriX as a medical image viewer are sometimes concerned as to whether the software has been approved by the FDA. While we will get to the answer, the real question is whether or not Horos or OsiriX meet the standards required for your specific use case.
Question: who owns my medical images? Answer: you can look but not touch.
It may amaze you to learn that the X-rays, CT Scans & MRIs of intimate parts of your anatomy are not your property. Pretty shocking, huh? In fact, the imaging center or hospital that took these images owns the title (copyright) to the image itself and the media on which it exists. So, it shouldn't come as a surprise that many doctors are reluctant to provide their patients with these images.
