The comment [0] mentioned that they could not get at all the mri outputs even with the radiologist coming on site. Obviously, software that was processing/exporting the data was running on a computer that was connected online, if not requiring internet connection itself. Data transfer can happen from another computer than the one the data is processed/obtained. Less convenient, but this is common practice in many other places for security and other reasons.
I mean, this is incentivized by current monetization models. Remove the need to go through a payment based aaS infra, and all the libraries to do the data visualization could be running on the MRI dude's PC.
-aaS by definition requires you to open yourself to someone else to let them do the work for you. It doesn't empower you, it empowers them.
Yeah I suspect -aaS monetisation models are one of the reasons of the current all-to-internet mess. However, such software running in the machine using a hardware usb key as authenticating is not unheard of either in software like that. I wish that decisions on these subjects were done based on the specific needs of the users rather than the finance people of -aaS companies.
