I'm not sure serial cables are the best medium for transmitting digital X-rays for instance. With 3D imaging, this images generate a lot of data. This data has to be saved somewhere, and SCSI over RS-232 was never the big thing.
Also a doctor might have to send a patient to a remote location, but still have access to the images in his own office. A dedicated network should be the goal, but it is not realistic to establish such a net over long distances. BTW, I'm from Norway, where you could drive for miles without seing a single MR-machine....
You might want to do RAID 0+1 instead. That is, a stripe of mirrored disks.
Why? If you have ten disks in a mirrored stripe and loose one disk in each stripe you loose. If you have a stripe over mirrors, you can loose a disk in each mirror and still access all data (but it's time to check those backups...) With four disks, it would be the same. Add more disks and a stripe over mirrors is safer.
Someone could calculate the probabilities of loosing data in the two setups, but you have a better chance with striped mirrors. The performance should be the same.

Still confused? You're not alone...
