Paper Abstract

A frequency scanning beam steering technique using an alternating polarity transducer array is investigated for presentation of B-mode ultrasound images for front viewing intracavitary applications. Arrays of alternating polarity PZT elements were computer simulated and fabricated to characterize their beam steering and resolution capabilities. A spherical lens was mounted in front of the array to improve focusing. A personal computer based system was used to test and generate sector images of wire targets using these arrays.
