Abstract
Diagnostic medical ultrasound systems generally use only a portion of the available bandwidth of modern transducer arrays. A new method is presented that makes optimal use of all available bandwidth. This method achieves improved lateral resolution with no loss of frame rate. The performance of the method in the presence of tissue related phase aberration and attenuation is considered. The key elements of the additional electronic hardware required to support this technique are discussed. The extension of the method to use with 1.5D arrays and annular arrays is also discussed.
