Abstract: 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.

Abstract: A system and method is disclosed in which a switch is located between the I/O hubs of the computer system. The I/O hubs are coupled to I/O devices of the computer system. The I/O hubs are also coupled to one or more processors via direct point-to-point communication links. The I/O hub provides a connection point between various I/O devices and processors. The switch includes a set of internal communications pathways that can be set according to the communication status of links between the processors and I/O hubs of the system. When the communication links of the system are operational, the switch allocates all of I/O hub transmission bandwidth to I/O devices. When the communication links are determined to be not operational, the switch allocates some of I/O hub transmission bandwidth to establish a communication link between the I/O hubs of the computer system, while the remaining I/O hub transmission bandwidth is allocated to I/O devices.
