Abstract: A method and system is presented which provides a TDM framework for managing self-describing measurement data. The TDM framework provides applications with a central platform for accessing measurement data across an entire enterprise system.

The space requirement for adding new coils is reduced, and the modular design makes it possible to easily implement any three-dimensional or two-dimensional shape.
