Radiologist reading studies from home
A radiologist on overnight call connects from a home workstation to a high-end imaging machine sitting in the hospital data center. The diagnostic monitor stays calibrated where the studies live; the radiologist sees a true colour-accurate 4K stream at sixty frames per second. No DICOM bytes leave the hospital network — the pixels on the radiologist's screen are an encrypted rendering of the remote display, not a copy of the underlying study.
When the read is complete and the workstation locks, nothing remains on the home device. The study lived where the studies live; the radiologist visited it.
