Abstract
Radio-frequency (RF) ultrasonic data carry complete information about the object to be analyzed. Conventional analysis methods consist of exploiting only one-dimensional envelope information of the RF data, phase information being often neglected. A method is presented that is based on exploiting two-dimensional spatial phase information of RF data through the use of Gabor and Mexican hat filters. The method is illustrated with the aid of examples on physical RF data. The obtained results demonstrate the interest of spatial phase for the detection of objects in RF ultrasonic images
