Confession time. I'm afraid I'm part of that problem.......
The thought that technology will always improve lives is a largely American phenomenon (based on my travels, which are quite extensive). There comes a point where that technology becomes unaffordable and begins to drain the economy. I believe we hit that point in the early 90's and are now reaping the rewards for our shortsightedness.
Anyone wanna venture a guess as to how much it costs to deliver and site a magnet? There's a reason that the scan of your leg costs 2 grand. Who's gonna pony up? You? Me?

Of course not. Insurance will or John Q Public eats the cost (in urgent/emergent cases).
I can tell you, there's nary a gadget that I use which costs less than 5 figures. All of them are considered vital in the chain of care which we provide to patients. New technology = new treatments, but it also means new costs associated with those treatments. In the case of a typical rad onc treatment, that's the cost for the linear accelerator (or gamma knife, SRS, etc), CT, x-rays, labs, treatment planning and/or brachytherapy afterloaders, nurses, dosimetrists, and last but not least those greedy doctors (yours truly) who are responsible for ensuring that the entire platter gets delivered to your table properly.
Think about it. That scheme is a non-starter in 1905 America. Today? It's killing us and there's no stopping the train, the insurers know this. Keep in mind I speak only about my sub-specialties (Radiation Oncology, Radiology, Nuclear Medicine). This conundrum applies all across the board to a greater or lesser degree.
