Abstract  Abstract

A nonlinear dynamic focusing control method, comprising (1) setting the minimum length of a scan line having a minimum length and a maximum length as a initial position and allocating focusing points on the scan line; (2) calculating a half of depth of focus of the focusing points and setting the focusing point in a location on the scan line as the initial position plus the half of depth of focus; (3) setting a calculation initiating position of next focusing point as the location of the focusing point plus the half of depth of focus of this focusing point toward the direction of the maximum length; (4) determining whether the calculation initiating position of next focusing point is bigger than the maximum length or not, if no, replacing the initial position as the calculation initiating position of next focusing point and repeat steps (2) and (3), if yes, finishing the calculation; wherein the location of focusing points on the scan line are nonlinear distributed in accordance with the shift invariance property of point spread function. Therefore, the disclosure more effectively allocates the focusing points and reduces the calculation complexity of an image system with transducer array.
