Abstract :
A new approach for 3D acoustic imaging using a 2D receiver array and a 2D transmitter array is proposed. The proposed method utilizes synthetic transmit aperture (STA) technique and a power radiation pattern of a transmitter. The STA technique has been used in acoustic imaging for reconstructing high quality images by using a few transmission events. However, it assumes that a transmitter produces equal energy over the imaging area. This leads to a deterioration of images especially when a 2D transmitter array is used. The proposed method integrates a power radiation pattern of a transmitter into STA technique to compensate the non-ideal radiation of the transmitter. The reconstructed images from the proposed method show the improvement in terms of image quality.
