Abstract: A flexible design of a transmission system for a magnetic resonance tomography apparatus has multiple radio-frequency control units, connectors that are connected to the radio-frequency control units, a unit to which at least one first connector is connected, which connector is also connected to a first radio-frequency control unit of the radio-frequency control units. The unit is connected via a connector to only some—in particular only one—of the radio-frequency control units. One of these few radio-frequency control units is connected to an additional radio-frequency control unit via an additional connector.

Abstract: In a transmission error logging device, method and computer-readable medium for logging transmission errors that occur on a high speed transmission route of a medical technology diagnostic apparatus, the in-feed port for a signal is provided on the high speed transmission route and an error signal is generated upon detection of an error. The transmission volume is detected by a transmission volume counter and the number of errors is detected by a transmission error counter. The transmission volume counter makes a transmission volume count, representing the transmission volume, available as an output from the transmission volume counter, and the transmission error counter makes a count of the number of errors detected by the error detection device available at an output of the transmission error counter.

Abstract: Optimized transmission system for an MRT is achieved by a device and a method to generate transmission signals (29) via multiple transmission units of a transmission system for a magnetic resonance tomography system, wherein transmission data are respectively received from the transmission units via a transmission data input, received transmission data are stored in transmission data memory elements of the transmission units, transmission signals representing stored transmission data are generated with transmission data (stored in transmission data memory elements) by transmission signal transmission units of the transmission units, and the generation of transmission signals proceeds simultaneously via the transmission signal transmission units.

Abstract: In a method for the production of a radio-frequency signal modulated as a function of a low-frequency digital data stream, a clock signal is provided having a frequency that is at least four times as high as the frequency of the radio-frequency signal to be produced. The clock signal is used for mixing the low-frequency data stream with a cyclical numeric sequence representing a continuous sinusoidal or co-sinusoidal series. A circuit arrangement implements such a method to produce a radio-frequency signal modulated as a function of a low-frequency digital data stream, and a magnetic resonance tomography system employs such a circuit arrangement.

Abstract: A modulator for radio-frequency signals designed an entirely digital modulator has two mixer stages connected in series. The first mixer stage implements with a relatively low first sample rate a frequency mixing with a first oscillator frequency that is adjustable with high precision. The second mixer stage implements a frequency mixing with a significantly higher second sample rate and with a relatively coarsely adjustable second oscillator frequency. The downstream second mixer stage, in the case of a single mixer stage, the mixer stage, has at least two phase accumulators that are incremented with the higher second sample rate but with different incremental values. The output signal of at maximum one of the phase accumulators is evaluated at any point in time.
