Abstract
The invention generally relates systems and methods to for producing an image from a rotational intravascular ultrasound device. A method can include alternately transmitting complementary Golay codes to a plurality of transducers in a intravascular ultrasound device; receiving echoes of the complementary codes from the transducers; performing pulse compression of the echoes that comprises weighting the received echoes and summing an odd number of weighted echoes, wherein a center echo is given a weighted value of 1.0 and weighted sums of its neighbors constitute complementary echoes of a Golay pair; and producing an image from the compressed echoes. A system can include a processor; and a plurality of beam modules coupled to the processor, each module comprising: a receiver for receiving a trigger signal from the processor; a complex programmable logic device programmed with a Golay code; a high voltage switching transmitter; and an ultrasound transducer.
