Architecture for the cascaded signal selection and signal - concentration and / or reduction of digital data by decimation and channel advance selection

摘要

The present invention relates to a magnetic resonance imaging system (101) with a plurality of (s) mrt - plugs (1, 2, 5, 6; 3, 4, 7, 8) for the connection of (m1, z) antenna elements (at1 - 1. at1 - 3, at2 - 1. at2 - 3, at3 - 1. at3 - 3) in each case one of a plurality of local coils (106 - 1, 106 - 2, 106 - 3),wherein, by at least one analog switching matrix (sb1, sb2) in each case at less (m2) than all (m1) of the mrt - plug (1, 2, 5, 6; 3, 4, 7, 8) connected to the antenna elements (at1 - 1. at1 - 3, at2 - 1. at2 - 3, at3 - 1. at3 - 3) with the reception signal processing elements (rx - ch) of one of several, in each case a plurality of reception signal processing elements (rx - ch) having a reception signal processing elements - blocks (rx24, rx18) can be connected in a manner similar to that of,and wherein between the outputs of the reception signal processing elements - blocks (rx24, rx18, rx32) and an evaluation unit (117, 110, 120) of the magnetic resonance tomography system (101) a digital - channel - selective heavy-duty - unit (sc) is provided, which is connected on the inlet side (adc) with antenna elements (at1 - 1. at1 - 3, at2 - 1. at2 - 3, at3 - 1. at3 - 3) can be connected (sb1, sb2, rx18; rx24, adc, o / e), wherein at the output of the digital - channel - selective heavy-duty - unit (sc) signals of less antenna elements (at1 - 1. at1 - 3, at2 - 1. at2 - 3, at3 - 1. at3 - 3) than at the input of the digital - channel - selective heavy-duty - unit (sc) bear.
