Abstract:
1. A computer tomograph comprising a rotating part and a stationary part, with a system for transmission of data between the rotating part and the stationary part, in which the rotating part comprises: at least one data source; at least one first transmitter means for receiving data from the data source and converting received data to data signals for transmission to the stationary part; and a first transmitter antenna arrangement for transmitting the data signals; wherein the stationary part comprises: a first receiver antenna arrangement for picking-up data signals transmitted by the first transmitter antenna arrangement; at least one first receiver means for receiving data signals from the first receiver antenna arrangement and converting the received data signals for relay of data to a data sink; at least one data sink for evaluating data relayed from the receiver means; and a patient's table adapted to move along a direction of an axis of the rotating part; wherein at least one of the first transmitter antenna arrangement and the first receiver antenna arrangement is a diversity antenna system; wherein the system for transmission of data comprises a control unit configured to selectively employ a phased array antenna system, which comprises a plurality of radiators of the first transmitter antenna arrangement for transmitting in phase relationship with each other, so that a definite radiation pattern may be obtained in its entirety; and wherein patterns for the individual antennas are obtained in dependence upon the relative position of the rotating part to the stationary part by retrieving position dependent preprogrammed radiation patterns.
