The Army Combat Support Hospital (think MASH tv-show...) guys could set something up like this really fast, but it was expensive hardware, required their own personnel, etc. This makes sense for the US military (massive logistics, budget, etc.), but not for others. Also worked (volunteer/charity) with some local clinics who didn't have these kind of resources, but did have great personnel, who could use more locally-acquired or bespoke solutions -- problem was it was slow, not uniform standard, etc.
A cost-reduced, standardized, easily transportable hybrid is great. Ideally you'd use existing standardized readily available stuff with minimal medical/flown in stuff on top.
