Abstract :
We present initial results from a new 1.75D array. The advantages of this array include: 1) Improved elevation focusing, 2) More effective phase aberration measurement and use of adaptive imaging techniques due to the increased sampling in the elevation dimension, 3) The ability to obtain individual channel data, and 4) Harmonic imaging capability
