Abstract:
1. A method for transmitting wanted signals between a sensor and an evaluation unit of a PET detector, the method comprising: detecting a wanted signal by a signal receiver with the sensor for detecting the wanted signal and a signal processing device for conditioning the wanted signal, with a mixed signal with a wanted signal component and an interference signal component from a gradient coil system of a MRI magnet acting as at least one interference source being present at an output of the signal receiver, wherein the wanted signal component includes a PET detector signal; importing at least one interference source signal of the at least one interference source from a preamplifier of the interference source, the interference source signal being a set of control signals for controlling switching of the gradient coil system; and reconstructing the interference signal component as a function of the imported at least one interference source signal in a linear filter with a filter transmission function and subtracting the reconstructed interference signal component from the mixed signal in order to recover the wanted signal component.
