Magnetic resonance tomography system, receive apparatus and method |
摘要 |
A magnetic resonance tomography (MRT) system has a receive apparatus disposed in a magnetic field, in which a receive coil is coupled to an input of an analog/digital converter. The analog/digital converter is configured for this purpose. A digital output of the analog/digital converter is coupled via a digital mixer device and a clock-rate-reduction device to a data output of the receive apparatus. The mixer device is configured to mix a predetermined frequency band of the MR signal downwards into an intermediate frequency range and create a digital IF signal. |

1. A magnetic resonance tomography (MRT) system comprising:
a device for creating a magnetic field, through which a magnetic resonance is creatable in a body; and a receive apparatus disposed in the magnetic field, at least one receive coil of the receive apparatus configured for receiving an MR signal of the body being coupled to an input of an analog/digital converter, wherein the analog/digital converter is configured to convert the MR signal into a digital MR signal by direct converting, wherein a digital output of the analog/digital converter is coupled via a digital mixer device and a clock rate reduction device to a data output of the receive apparatus, wherein the digital mixer device is configured to mix a predetermined frequency band of the MR signal downwards into an intermediate frequency range and to generate a digital intermediate frequency (IF) signal, and wherein the data output of the receive apparatus is coupled via a data transmission device to a data input of an RF-shielded evaluation device. |
