The present invention provides a method for positioning an electromagnetic tracking sensor. The method includes attaching a sensor to an anatomy, obtaining an image of the anatomy, indicating a size of each of a plurality of volumes on the image, where the volumes include a smaller and larger volume, and making a determination of whether a region of interest is encompassed by one or more of the volumes. The present invention also provides a system for positioning an electromagnetic tracking sensor. The system includes a sensor attached to a patient anatomy, an imaging modality obtaining an image of the anatomy, an image processor indicating a size of each of a plurality of volumes on the image, where the plurality of volumes includes a smaller and larger volume, and an operator making a determination of whether a region of interest is encompassed by one or more of the volumes.

The present invention provides a method for hierarchical state based migration of data. The method includes determining one or more constraints and/or global parameters for migration of data from a first storage location to a second storage location, allocating copy and updating resources to copy data from the first storage location to the second storage location based on at least one constraints and/or global parameter, altering at least one of the constraints based on one or more states of the data in the migration, and reallocating at least one of the copy and/or updating resources during the migration based on the altering step. The present invention also provides for the hierarchical migration of data by assigning tasks and/or responsibilities for the migration to various components of a hierarchical system.
