Abstract
An apparatus, system and method for calibrating a movable receiver coil with spatially varying signal reception profile in a magnetic resonance imaging environment is described. The method of the invention calibrates the movable receiver coil with spatially varying signal reception profile by dividing the receiver coil into parts and determining electromagnetic interactions of the parts in the environment. The method further includes (1) estimating orientation and position information corresponding to the receiver coil and (2) associating electromagnetic interaction data with records such as (a) responses of the receiver coil in various tissue environments to emissions caused by stimuli from external magnetic resonance coils, (b) high-resolution external receiver coil records of emissions from same environments, and (c) measurements of self-interactions and mutual interactions among the parts of the receiver coil.
