Abstract

There are provided an ultrasound image generating apparatus, which generates a high-quality ultrasound image even in a deep portion of a subject, and a control method thereof. In an ultrasound image (Img), for a portion (Ar1) equal to or less than a depth threshold value (D1), a real scanning line (L1) obtained from an acoustic wave echo signal is used. In the ultrasound image (Img), for a portion (Ar2) deeper than the depth threshold value (D1), an interpolation scanning line (L2) located between the real scanning lines (L1) is generated from an acoustic wave echo signal having a positional deviation between a focusing position of ultrasound waves and an observation target position. Also for a portion deeper than the interpolation scanning line (L2), a high-quality ultrasound image (Img) is obtained.

Dependent claims

An acoustic wave image generating apparatus, comprising:

an acoustic wave probe in which a plurality of acoustic wave transducers are arranged in an arc shape;
a driving device for making the acoustic wave transducers transmit acoustic waves converging on a focusing position to a subject while updating the acoustic wave transducers for transmitting acoustic waves in a sequential manner;
a real scanning line generation device for generating real scanning lines indicating an acoustic wave image of the subject using an acoustic wave echo signal indicating an acoustic wave echo from an observation target position of the subject that is obtained based on driving of the acoustic wave transducers by the driving device;
an interpolation scanning line generation device for generating a first interpolation scanning line located between the real scanning lines using the acoustic wave echo signal, which has a positional deviation in the arc direction between the focusing position and the observation target position, for a portion deeper than a depth threshold value in the subject;
and
an acoustic wave image generation device for generating an acoustic wave image of the subject from the real scanning line and the first interpolation scanning line.
