Abstract
An ultrasound imaging system uses a synthetic transmit aperture method with prefocused subapertures. The transmit aperture is divided into several subapertures. Transmission is done sequentially on each subaperture while receiving on the full aperture. The received data sets are then combined using the appropriate delays. In this way the focusing performance of a composite focusing system using a number of focal zones equal to the square of the number of subapertures is achieved. The gain is an increase in the frame rate which is also equal to the number of subapertures used.
