Abstract
To transmit electrophysiological data from an interference region (S) of an MRI arrangement (20) to an evaluation and/or display unit (10) a signal is handled in a recording arrangement (1) arranged within the interference region (S). The ECG signal (E) is first subjected to analogue above-linear compression, is then digitized and is transmitted as a digitized signal (D) to an evaluation and/or display unit (10). The digital signal (D) is subjected to above-linear digital expansion in the evaluation and/or display unit (10).
Claims14
A method for acquiring electro-physiological data in a recording arrangement and for transmitting the data to an evaluation and/or display unit, said method comprising steps of:
- acquiring a signal in the recording arrangement, above-linear compressing of the signal in order to form a compressed analogue signal,
- converting the compressed analogue signal into a digital signal,
- transmitting the digital signal to the evaluation and/or display unit, and
- expanding the digital signal digitally into a expanded digital signal,
- displaying and/or processing the expanded digital signal.
