Abstract
The invention relates to a circuit arrangement for generating rf signals for MR examinations, comprising a read-only memory in which a signal is stored in the form of a series of data words, an address generator for reading data words from the read-only memory with a clock frequency, and a digital-to-analog converter which succeeds the read-only memory. In order to reduce the required storage capacity, a sinusoidal signal in the form of a series of data words is stored in the memory.
