...but why?
I don't work in the medical field and am I'm not up on all the requirements of medical imaging, but this seems like a mashup of hot tech buzzwords in search of a problem. AI! ARM! 4K!
Is it for development of medical software? If so, then what exactly is the benefit of making it an all-in-one?
Or is it for deploying into a clinic, where space might be limited? If that's the case, then can anything actually use all that compute power? Does the current workflow run on ARM? Does it have the ports and software support to interface with existing imaging machines? My impression as a patient is that imaging machines come with their own specialized control and processing systems, then a pretty average Windows workstation is used for review and sharing of results. Which rather than running "many apps at the same time," tends to just be running the viewer app for the results at hand, a really dated looking frontend to their patient record database, a calendar, and maybe an in-office messaging program.
And maybe you could have a fully-local AI that checks scans and flags areas for further review by a human operator or closer-up scanning, which reduces the issues of sending that data out to someone else's data center... but their ending disclaimer makes it sound like rather than this being the appliance to run something they've cooked up, they're just chucking hardware out there on the assumption that the software will be built.
