ABSTRACT:
Disclosed is a system for identifying which one of a plurality of interchangeable transducer heads is connected with an ultrasonic scanner. The system includes a unique impedance mounted on each transducer head and an impedance determining circuit in the scanner for determining the impedance of the interconnected transducer head. The impedance determination circuit is connected to a character generator for producing an alpha-numeric representation of the transducer head designation along the margin of a cathode ray tube on which an ultrasonic image is displayed. Also disclosed is an improved resolver mounting in which a cylindrical axle is used as a pivot pin between two scan arms of the ultrasonic scanner. A potentiometer for resolving the angle between pivotally connected arms is mounted on one arm with its shaft resiliently connected with the axle for rotation with the axle and other scan arm.
