ABSTRACT:
A magnetic resonance system has a number of components including a basic magnetic field generation unit, gradient coils as well as a radio-frequency coil arrangement. The components are respectively controllable according to a control sequence via at least one digital module and at least one analog module. The analog modules are arranged external to a control computer that controls the digital modules. The digital modules are likewise arranged external to the control computer and are associated with the analog module or modules controlled via the control computer. The digital modules are networked via the following networks for communication of the digital modules among one another and/or with the control computer: a synchronous first network to synchronize the digital modules, an isochronous or semi-isochronous second network, a third network, wherein the digital modules are connected with the control computer via serial peripheral component interfaces and a signal transmission between the peripheral component interface of the respective digital module and the associated peripheral component interface of the control computer thereby occurs on optical paths.
