Abstract
An improved pulse-echo ultrasonic-imaging system for scanning, in real time, objects such as soft tissue within a living human body. It employs a transducer including first and second parallel wave-energy generating electrodes extending linearly in a first direction and a linear array of image-spot detecting electrodes also extending in this first direction and is situated half-way between the first and second electrodes. Scanning in a second direction orthogonal to the first direction is provided by counter-rotating Risley prisms rotating at a predetermined rate. The distance between each of the first and second electrodes and the linear array is related to this predetermined rate such that reflected wave energy is always directed to the linear array.
