Abstract
A linear array for rectilinear and sector scan imaging has identical approximately diamond-shaped transducer elements fabricated by making two pairs of straight line cuts at small angles through a piezoelectric slab. The Y-axis radiation pattern (parallel to element length and perpendicular to the array length) has lower side lobe levels than equal sized rectangular elements. No changes in the imager electronics among channels is required, and the shading function may be modified by changing only the transducer.
