摘要： A feedback circuit is provided for reducing the input impedance of a preamplifier circuit, such as for use with a sensing coil in an imaging system. The feedback circuit permits adjustment of the input impedance by balancing inductive and capacitive components of a feedback control circuit. The imaginary component of the input impedance may be adjusted independently of the real component, to provide a substantially zero input impedance, while allowing adjustment of the stability of the system. The circuitry may function in conjunction with a reactance matching circuit to reduce cross-talk in multiple sensing coil arrangements.

摘要： A technique for managing data relating to peripheral devices and subsystems in an imaging system includes providing memory circuitry and, where desired, signal processing circuitry resident in the peripheral devices. Manufacturing data, identification data, service record information, calibration data, and other relevant information may be stored directly in the peripheral devices. The circuitry of the peripherals and subsystems may also include sensors and encryption circuits, and circuits for interfacing the memory and processing circuitry with other components, particularly a controller for an imaging system. The peripherals may include coils and drivers for MRI systems, tables, patient monitors and any other device pertinent to an MRI system. An initialization sequence is performed upon connection of the peripheral to the system, to identify the peripheral and to transfer information needed for examination sequences and other MRI procedures.
