Abstract:
The invention relates to a device (1) for magnetic resonance imaging of a body (7) placed in a stationary and substantially homogeneous main magnetic field comprising a main magnet (2) for generation of a stationary and substantially homogeneous main magnetic field within the examination zone. In order to provide an MR device (1) which is arranged to allow for massive parallel imaging without extensive cabling between the individual receiving coils and the back end electronics, the invention proposes to make provision for a plurality of receiving units (10a, 10b, 10c) placed in or near the examination zone, which receiving units (10a, 10b, 10c) each comprise a receiving antenna (12a, 12b, 12c) for receiving MR signals from the body, a digitizing means (21a, 21b, 21c) for sampling the received MR signals and for transforming the signal samples into digital signals, and a transmitter (22a, 22b, 22c) for transmitting the digital signals to a central processing unit (13). Further, the device (1) comprises synchronization means (17) for synchronizing the operation of the individual digitizing means (21a, 21b, 21c) of the receiving units (10a, 10b, 10c).
