摘要：
Acquired echo data is corrected to reduce content from ultrasound that has undergone at least one reflection off the probe surface, for example, to reduce corresponding reverberation artefacts from imaging. In some embodiments, the propagation medium, i.e., layer or adjoining layers, through which the reverberation occurs, is, after a set of echo radiofrequency data (404, 408) has been acquired, modified in preparation for a next application of ultrasound. During that next application, it is the reverberating ultrasound signals (424), according to embodiments of the invention, that are more affected by the modification than are the non-reverberating, i.e., direct signals (420). This difference in effect is due, for example, to greater overall time of flight through the modified medium on account of reverberation in the propagation path.
