Being in the healthcare field ive asked around and although our institution owns a nanosonic, it is barely used - meaning minimal purchase of the high margin consumables. This is particularly the case when simple plastic disposable covers or antibacterial wipes will do (unless doing an invasive ultrasound- which is not overly frequent). 

Further risk is the new version 2 - which doesnt seem to be much of a benefit for a radiology practice owner. Yes it may mean tracking or auditing cleaning of ultrasound probes is easier, but it doesn’t  sound overly cost effective for radiology practices to upgrade? If services don’t upgrade their product and the patent runs out, surely competition will occur and margins will be pressured.

If nanosonics are able to adjust their technology to provide disinfecting for other medical products than that would be a game changer... although this doesnt seem to be the case (yet?)
