For a tiny valve that size, you'd almost certainly need to use a MicroCT scanner though. I dont know how many hospitals keep one on hand since they're very niche and there are obvious issues imaging anything living (movement, radiation exposure, etc). Its typically used outside of hospital environments for scanning. The large scanners won't give you the level of detail you'd need, at least not the ones I worked with.
