Abstract
The invention is a linear transducer array having an axis of rotation parallel to the long axis of the array. Accordingly, each transducer element is analogous to the single transducer of the traditional B-scan. All the elements are pulsed in rapid sequence as the entire array is swept mechanically, and a series of B-scan planes, displaced from each other by the transducer element spacing, are created. Display control electronics interpret the multiple planes with the resultant solid volume represented in isometric or perspective views on a CRT. Ultrasonic transducer arrays of 16 or more elements can be fabricated which would cover the entire volume of the eye in a single angular sweep.
