I'm working to gain an understanding of MRI equipment, specifically GE equipment, and I'm kind of confused by some of the terms that I see associated with the scanners when they are being listed for sale. Can anybody give me a quick idea about what is being talked about when they are referring to the "LX Platform" on a GE MRI scanner? I think it might have some relationship to phased array channels, but I'm not sure. I have also seen references to the "5X Platform" and the "Excite Platform", are these mutually exclusive to the LX platform (updated/prior models?) Thanks in advance to anyone with some GE experience who can help out.

The LX platform is the last generation of "Signa" MRI's using the SGI Octane computer platform. GE generally uses the software version to identify systems. The LX is a 9x system. The 5x was pre- LX. The Excite, HD and HDx are 11x 12 x and 14x sysyems and use HP host computers.

Marty,
Thanks for the information, it is very helpful. Do you know approximately when GE switched from 5X to LX, or from LX to Excite? Is it possible to upgrade a GE MRI from LX to Excite by replacing the workstation? Thanks again for your help.

LX platform was starting 1997; upgrade from 5x to LX (9.1) is the whole hardware except Magnet and table, LX was the last platform for 1.oT systems. All 1.5T and 3.0T system can be upgraded to 15x ( HDxT) platform but all magnets before LCC Magnet( starting 1998) have the limitation max. 8 channels. The upgrades from 11x to 15x have new computers plus parts of gradient cabinet and system cabinet and coils. For the new 750/450 platform it is more difficult to upgrade, kompl. new hardware.
