Optimization of the lateral resolution of a transducer.
This paper deals with the problem of optimizing the lateral resolution with respect to the velocity distribution of the transducer surface. In order to determine the acoustic field, the transducer is divided into circular annuli with a predetermined shape of the velocity distribution. The acoustic field from the transducer is a weighted sum of the fields from the annuli. The lateral resolution is optimized with respect to these weights. Examples are given to illustrate the method.
