An endoscope ultrasound probe for use with an ultrasound imaging system in transesophageal echo cardiography comprises a motorized positioning system which provides for automated control of an ultrasound transducer array. The positioning system employs an electric motor for rotating the array which is positioned in the distal end of the probe. A switch mechanism may be manipulated to provide power to actuate the motor. The motor is mechanically coupled to the array providing the capability to rotate the array to any angular position to provide a plurality of scan planes for obtaining a plurality of corresponding two-dimensional cross-sectional images. Further, the positioning system may comprise a position feedback mechanism coupled to the array for providing remote imaging system electronics with array position indications corresponding to each of a plurality of corresponding two-dimensional cross-sectional images. Also, the positioning system may be electronically controlled by a controller in the imaging system for providing three-dimensional images of a subject.
