Abstract: An MRI system includes an MRI scanner having a bore and a table configured to move a subject to be imaged into and out of the bore. The MRI system includes a flexible RF receiving coil array integrated within the bore and electronically coupled directly to the MRI scanner, wherein the flexible RF receiving coil array remains in the bore regardless of a position of the table, and the flexible RF receiving coil array is located underneath the table when the table is located within the bore. The MRI system includes an automated mechanism configured to automatically move the flexible RF receiving coil array from underneath the table on a first side of the subject, to pull the flexible RF receiving coil array over the subject from the first side to a second side of the subject, and to fasten the flexible RF receiving coil on the second side.

Abstract: 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.
