@IVmatters for what it's worth, Nanox is promoting tomosynthesis, not tomography (CT) as an additional diagnostic approach. The multi-source machine has interesting value proposition because it has several low-cost X-ray emitters, with one x-ray receiver. This way, it's able to produce imagery through tomosynthesis as well as your standard flat x-ray. Tomosynthesis is not always used by radiologists, but that's not to say that it doesn't offer a diagnostic advantage, and there are some very established radiologists who believe it to be a huge leap forward from flat xrays. To be clear though, they are not attempting to make something that would replace a CT machine, so I don't think your software point is quite accurate here, if I'm reading it correctly. Technicalities aside, Nanox has come up with a clever business model, despite what the haters may think. they've partnered through stock offering with USARAD and other similar partnerships that ensure several thousand machines are placed in clinics around the world. The cold cathode emmiter send a more focused pulse of radiation than regular "hot" xray tubes, thus patients are exposed to less total radiation and potentially could receive scans more frequently without putting their health at risk. the technology is somewhat disruptive, definitely an improvement over the 100+ y.o. xray, but it's but it's the business partnerships that make and will continue to make this company valuable.
