Two-directional phase aberration correction using a two-dimensional array
The aim of this paper is to show the effectiveness of two-directional phase aberration correction using real-time signals obtained from a human body. The authors constructed a two-dimensional array and the real-time data acquisition system for this purpose. The array has ten elements in both the scan and elevation directions. It is placed in contact with a human body and signals reflected from the subject's liver are digitized by parallel A/D converters and stored in memory. The data acquisition for each image is completed in 52.4 ms. A cross-sectional image of the liver is then constructed off-line with a computer. Images of the liver before and after the phase aberration correction show that the image was significantly improved after the compensation.
