It's not just 'right to repair' in the sense of fixing something that's broken which is at stake. The restrictions that OEMS place on medical equipment software prevents the owner-operator of the equipment from confirming that their scanner is operating properly. In many cases, a clinic has no mechanism to ensure that the device is operating within specifications or operating safely. This is obviously not a good policy for anyone but the OEM.
Industry veterans know that this is not just a hypothetical risk, but many of us can cite repeated examples where OEMs have deceived the public and covered up failures of scanners under their exclusive service, because there's no possibility of 3rd party oversight nor even oversight by the equipment's owner. This is a health and safety hazard and should be changed.

As to safety, as noted, there is very little difference in the safety record of OEMs vs In-House vs Third party. Only in the ability to cover it up. The performance bell curve fits all of the above. Both as an instructor for a big OEM and an In-House imaging servicer, I have seen the whole range of performance in both settings, whether hospital, third party or OEM servicers and called it out for praise/condemnation as appropriate. Both have great and bad and every level in between. The advantage is the OEMs can take a crappy warm body and feed it answers from a good support center; they are not willing to do this for just anyone. But they should and do for a fair price. Keys and access, there is not much real cost to provide these electronically, they were needed to develop the product and support their own engineers. The ask currently is really far from reasonable to smaller sites/independent servicers. As a Philips CT instructor said in front of a mixed class I was in, "FDA says we must give them [non-Philips servicers] the tools under FDA, but we don't have to make it easy for them" when asked why the tools were different/more integrated for Philips servicers compared to the limited if even available AIAT level of tool. Some that should have been available under AIAT were very hard to find if they were even provided.

Another thing to think about these days is the level of support available from the OEMs. They are all so short on service engineers, you will have a significant wait time to get anything fixed just do to the fact many of there current staff are pretty grey and retiring with few replacements coming on line. And the ones they have will likely burn out trying to keep up. If they cooperated more with their customers, they could have a quality field force supporting many of their sites without any real cost to them.

EOL? So, tell me how one CT system can be EOL with a 15 year old gantry and table system running a certain version of software and that same system with only a change of two computers and a newer software version is not EOL? No change in anything but the software. All the old parts in the gantry and table remained the same. But one OEM will not sell parts, provide keys, or docs for any EOL system, EVEN IF YOU HAVE THE LICENSE FOR THE SERVICE TOOLS!!! That is nothing more than forcing the customers to upgrade or buy new. OEMs think we can afford to change out everything every five to 10 years while we try to push everything to 10 - 20 years. Not sure what planet they live on, but the margins are not there. Not for a very long time.

This is just my personal rant/observation, and I am one of the grey ones. So yes, I have some self interest in this as I will likely need good care to be affordable without having to share meals with the pets in retirement. Imaging costs are a huge chunk of that pie.
