FMU
AnalyzerTM for WindowsR is a new Microsoft Windows based interface for the FMU-1200 magnetic field
mapping units. Launching of the new interface is expected to happen on
July 1st, 2006.
This project is being developed under the ISV partnership with
Microsoft and will support the following Microsoft software:. NET
integration, Windows Forms, C#, and Excel.
The
product is a porting to Windows of the standalone analysis package for
dataprocessing of robotically-acquired maps of magnetic fields in MRI
and NMR magnets. The Windows version will provide enhanced analytical
capabilities for this data.
