Phased Array Ultrasonic Imaging using Plane Wave Imaging Technique

Total Focusing Method (TFM) imaging has a limited frame rate because of the high storage and processing demands of large files acquired by Full Matrix Capture (FMC). Plane Wave Imaging (PWI) technique can be used to overcome this problem. PWI technique reconstructs an ultrasonic image that is virtually focused at any point in a region of interest using data set obtained by all the array elements individually for transmitting the plane waves at several angles. This technique typically reduces the number of signals that must be recorded and processed when compared to TFM/FMC; therefore, the frame rate can be improved considerably. In this study, we propose and validate a new algorithm for reconstructing PWI images, and we demonstrate that the PWI technique provides image quality similar to that of TFM while using a significantly less data
