Abstract
The paper deals with optimization of the transmit aperture in the multi-element synthetic transmit aperture method (MSTA) for ultrasound imaging. In contrast to the conventional synthetic transmit aperture (STA) method, MSTA allows to increase the system frame rate and provides the best compromise between penetration depth and lateral resolution.
The optimal choice of the transmit sub-aperture size and the aperture shift between subsequent transmissions is the most important question for efficient imaging with MSTA algorithm. Here the results of the analysis obtained by the developed optimization algorithm are presented. Maximum penetration depth and best lateral resolution at given depths were chosen as the optimization criteria. The numerical experiments were carried out in the MATLAB® environment for 128-element linear transducer array with 0.48 mm inter-element spacing excited by one sine cycle burst of the nominal frequency of 5 MHz. The wire phantom was simulated by FIELD II program. The transmit apertures up to 16 element wide were considered.
