Abstract
An intravascular Doppler ultrasonic device comprises a tip region forming a fraction of a catheter body at a distal end thereof and carrying an ultrasound probe. The tip region is bendable in a direction perpendicular to a longitudinal direction. An actuator is provided in the tip region, which is configured to receive actuation drive power provided through the catheter body and to exert to the tip region a bending moment of a controllable amount. An actuation controller is configured to control actuation drive power delivery to the actuator so as to control the amount of the bending moment. A Doppler spectrum analysis unit is configured to receive Doppler spectrum data and to determine from it a Doppler signal quality measure indicative of a signal quality of the Doppler spectrum. The actuation controller is configured to determine the actuation drive power in dependence on the determined Doppler signal quality measure.
