Abstract:
1. A measuring apparatus comprising: a probe having a plurality of elements each converting acoustic waves into an electric signal, said plurality of elements being arranged at least in a first direction; a moving mechanism for moving the probe in a second direction that crosses said first direction; a first delay-and-sum circuit for performing delay and summing in said first direction using a plurality of the electric signals obtained by said plurality of elements at individual positions along said second direction, so as to obtain a plurality of first add signals corresponding to a plurality of target points in an object within a slice plane, the slice plane being a plane parallel to said first direction and crossing said second direction; a signal extraction circuit wherein the first add signals pass through a plurality of cascaded delay circuits, the signal extraction circuit outputting in parallel a plurality of the first add signals corresponding to one of the target points, wherein the output first add signals are obtained from successive slice planes, and wherein delay times of the cascaded delay circuits are values corresponding to a scanning period for one slice plane; a second delay-and-sum circuit for performing delay and summing using the output plurality of first add signals, so as to obtain a second add signal; and an image processing circuit for generating image data of inside the object by using a plurality of second add signals corresponding to a plurality of individual target points.
