Patent number: 11747416Abstract: A preamplifier arrangement for an MRI system includes a preamplifier coupled to a loop of a multi-channel coil array of the MRI system, wherein the preamplifier and the loop are subject to potentially form an unstable system with oscillation at one or more peak frequencies. The preamplifier arrangement also includes an impedance matching network disposed between and coupled to the preamplifier and the loop. The impedance matching network is configured to generate a high blocking impedance. The preamplifier arrangement further includes an input network disposed between and coupled to the preamplifier and the loop. The input network is configured to provide an input to suppress gain at the one or more peak frequencies.Type: GrantFiled: April 8, 2022Date of Patent: September 5, 2023Assignee: GE Precision Healthcare LLCInventors: Robert Steven Stormont, Victor Taracila, Fraser John Laing Robb, Thomas Grafendorfer, Louis Jay Vannatta, Yun-Jeong Stickle
