Abstract: A medical diagnostics installation has an examination station at which a patient and medical examination equipment are disposed, and a control console disposed remotely therefrom. At least two different wireless control signal transmission channels are provided, each sending control signals to the examination station simultaneously by means of different types of information-carrying signals, such as an ultrasound signal and an infrared signal. Since the different types of information-carrying signals are affected by respectively different types of disturbances in the transmission path, the risk of an incoming control signal being misinterpreted due to the presence of a degraded signal is minimized.

Abstract: A DC-AC converter comprises a bridge of electronic switches having a load connected in one diagonal and the constant voltage source connected to the other diagonal. The two switches of each bridge branch are connected to one another by at least one resistor, the load being connected to one end of the resistor.

Abstract: An inverter, with a frequency lying in the medium frequency range, and a mains rectifier are connected with the high-voltage transformer. Between the X-ray tube and the high voltage transformer there is disposed a high-voltage rectifier with a high-voltage filter member. There is likewise connected with the filament transformer an inverter with a frequency lying in the medium frequency range and a mains rectifier. Filter members are connected between the mains rectifiers and the inverters. Plural inverters with different phase may supply respective high voltage transformers, and each transformer may have a voltage doubler high voltage rectifier contributing to X-ray tube anode voltage.
