  • Dual element ultrasonic transducer probe for combined imaging of tissue structures and blood flow in real time
    Patent number: 4893628
    Abstract: An ultrasonic probe for use in combined and time shared ultrasonic imaging of biological tissue structures together with blood velocity measurements and imaging of blood flow based on the Doppler principle, in which rapid changes of sweep movements of the probe between the respective imaging and measurement modes of operation are performed, said probe having two mechanically steerable ultrasonic beams, comprising:a linear motion electric drive motor having a stationary magnet means and a coil assembly which is linearly moveable with respect to said magnet means by the application of electric current to said coil assembly,two ultrasonic transducers for emitting respective ultrasonic beams and disposed to be pivotable around separate axes within separate angular sectors for sweeping the two ultrasonic beams within the two separate angular sectors, respectively,mechanical coupling assembly for connecting the linear drive motor to the pivotable transducer elements, converting the linear motion of the motor coil a
