A method of operating a multi-coil magnetic resonance imaging system is disclosed which includes a controller performing a simulation using a predefined tissue model, determining output values of a variable of interest (VOI) associated with operation of two or more coils of an MRI system based on the simulation, comparing the simulated output values of the VOI to an a priori target values of the VOI, if the simulated output values of the VOI are outside of a predetermined envelope about the a priori target values of the VOI, then performing an optimization, wherein the optimization includes iteratively adjusting the circuit values until the simulated output values of the VOI are within the predetermined envelope about the a priori target values of the VOI thereby establishing VOI optimized values, and loading the established VOI optimized values and operating the magnetic resonance imaging system on the tissue to be imaged.

Hybrid spatial and circuit optimization for targeted performance of MRI coils

A method of operating a multi-coil magnetic resonance imaging system, is disclosed which includes establishing initial circuit values of a drive circuit, loading a tissue model associated with a tissue to be imaged, loading target values for a variable of interest (VOI) associated with operation of two or more coils of a magnetic resonance imaging system, performing a simulation based on the established circuit values and the loaded tissue model, determining output values of the VOI based on the simulation, comparing the simulated output values of the VOI to the loaded target values of the VOI, if the simulated output values are outside of a predetermined envelope about the loaded target values of the VOI, then performing a first optimization until the simulated output values are within the predetermined envelope.

An apparatus for detecting RF signals in magnetic resonance testing procedure includes a multidirectional stretchable fabric and a flexible radio frequency (RF) coil. The flexible RF coil has a coil shape, and comprises conductive fiber stitched into the stretchable fabric in a plurality of repeating, non-linear stitch patterns. The plurality of stitch patterns collectively define the coil shape.
