<P>PROBLEM TO BE SOLVED: To provide an ultrasound diagnostic apparatus and an ultrasound image producing method capable of efficiently obtaining data for producing a B mode image and data for measuring the sound speed to achieve production of both a B mode image and a sound speed map. <P>SOLUTION: Transmission focuses are formed at lattice points E in a region of interest R to preferentially obtain reception data for measuring a sound speed, transmission focuses are formed at points F located at a given depth L set on each of sound rays S1-S7 during producing of a sound speed map in the region of interest R based on the obtained reception data for measuring a sound speed to obtain reception data for producing a B mode image, and both the B mode image and the sound speed map are produced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
