In reply to mypyrex:
On a similar vein, when I was accompanying a relation having radiotherapy, it was on a brand new £million+ machine, and we were told it was a huge advance in treatment as they could programme and target multiple doses of radiation in complex and variable 'bursts', as opposed to the usual single blast from one direction.
The consultant said it was such an advance, helping them to treat much more complex cases, and patients were coming from all over the North of England to be treated on it.
I asked if they would be looking to get another one, and she replied, 'oh we do have another one, in the next room, but staff cuts have meant we have no-one to operate it.
I believe (across the NHS) there are usually funds available for acquiring whatever equipment is required, but they can't afford to operate them.
