Figure 7

Intensity distributions in the focal plane along the y-axis (x = 0) transverse to the rib direction. The distributions were calculated in water for all elements switched on and no ribs present (curve 1), when all elements are switched on and ribs are in beam path (curve 2) and when ribs are present but some elements switched off to minimize the ultrasound impact on ribs (curve 3). The distributions were normalized by the element intensity I0, and ultrasound propagation was considered as linear.
