You may not need exclusive access to one, which is why a lot of institutions setup "centers" for this type of work (center for visualization, for example). Then multiple people can share the equipment and cost - if you can recruit people with a similar research focus. So, you may not need one exclusively, but you do need one locally available.
Seems like many samples could be prepared locally and shipped to the analysis center ala Netflix. Another possibility would be making samples to order at a location near where the necessary equipment is located. For instance, I need a brain tissue sample from xxx type of mouse, infected with pathogen yyyy.
