Disclosed is an injection system () for injecting liquids within a strong magnetic field, an alternating magnetic field, and/or a high-frequency electric field to be used with a technical medical system. Said injection system comprises a space () that is shielded from electromagnetic fields with the aid of a shield, an injection device () by means of which liquid to be injected can be dispensed to a patient (), a driving mechanism for the injection device (), by means of which at least one conveying element () can be displaced for injection purposes, and a control and monitoring unit () which is located outside said space (). The inventive injection system prevents interfering electromagnetic fields from being created exclusively by the fact that a hydraulic driving mechanism () is provided whose at least one hydraulic conduit () is guided out of the space () to a pressure generating unit ().

Hydraulic injection system and injection method

A process and system are disclosed for supplying electrical energy to a device located in a room housing an imaging system (such as an MRI system, for example), wherein the room is shielded from external electromagnetic fields. Certain embodiments of the present invention provide systems and processes for emitting electromagnetic radiation in the wavelength range of the light spectrum from at least one light emission device. Embodiments of the present invention further provide a process and system for transforming the electromagnetic radiation into electrical energy using at least one transducer device located in the room, and supplying the electrical energy to the device so as to minimize interfering electromagnetic fields within the room.
