Abstract

Recent advances in dynamic scanners resulted in construction of high resolution linear array transducers that have rapidly become the most popular instruments in ultrasound examination. Nevertheless the apparent resolution of the resulting scans is degraded due to the structure of the displayed image which is formed by separated scan lines. In this paper we propose a new system of optical processing which allows both to enhance the effective resolution and to suppress the raster.
