We have been performing TCD studies with an aging Neuroflow M2
originally manufactured by Neuroguard.  For some years the system had
been supported by Nicolet/Viasys.  Recently it has developed a software
problem which has rendered it inoperable and Nicolet/Viasys has informed
us that the system has been retired and that they can no longer offer us
any parts, documentation, software or service of any kind.  We may need
to purchase a new system.

1.  Does anyone know of any other person or company that can service
this machine or, at least, offer a copy of the Neuroguard software so
that we may attempt to reinstall it and possibly get the system to work
again.

2.  Does anyone have any experience with the TCD system marketed by
Terumo Cardiovascular?  If so, what is your experience and opinion?  How
does it compare with the systems marketed by Nicolet/Viasys?

If you would rather contact me directly it can be via email at
[log in to unmask] or via telephone at 718-818-1095.  Any assistance or
feedback will be greatly appreciated.
