<P>PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus having a function of sampling reception signals by use of a plurality of sampling frequencies respectively corresponding to an interest region and a non-interest region. <P>SOLUTION: This ultrasonic diagnostic apparatus includes: a transmission part supplying a drive signal to each ultrasonic vibrator; a reception signal generation part generating the reception signal of each depth in each scanning line inside a scanned line region based on each echo signal generated by each ultrasonic vibrator; a sampling part sampling the reception signal corresponding to a first region set inside the scanned region by use of a first sampling frequency corresponding to the depth of the first region, and sampling the reception signal corresponding to a second region having the depth different from the first region by use of a second sampling frequency lower than the first sampling frequency; and an image generation part generating an ultrasonic image based on the sampled signals. <P>COPYRIGHT: (C)2013,JPO&INPIT |
