Beschreibung
Zusammenfassung:	An ultrasound imaging catheter comprises an ultrasound transducer array provided at a distal end of an ultrasound imaging catheter. The ultrasound transducer array comprises a plurality of ultrasound transducers and is adapted to transmit and receive ultrasound signals. The ultrasound imaging catheter includes a local memory provided at the distal end of the ultrasound imaging catheter. The local memory is adapted to store a plurality of activation patterns, each activation pattern corresponding to a number of transducer elements of the plurality of transducer elements to be activated and a number of transducer elements of the plurality of transducer elements to be deactivated. The ultrasound imaging catheter includes a control unit provided at the distal end of the ultrasound imaging catheter adapted to: access the local memory; select any one of the plurality of activation patterns; and generate a control signal to activate or deactivate the plurality of transducer elements of the transducer array according to the selected activation pattern during an imaging phase of the ultrasound imaging catheter.
