Abstract:
An ultrasonic diagnostic apparatus for forming a three-dimensional image using a reflection wave of an ultrasonic beam, comprising:a three-dimensional ultrasonic scanning unit for carrying out a three-dimensional ultrasonic scanning by a plurality of ultrasonic transducers arranged two-dimensionally and forming detection signals corresponding to reflection waves reflected from a subject that are detected by the transducers;a first delay add processing unit for dividing detection signals from all the transducers into a predetermined plurality of partial signal groups and carrying out delay add processing to each of the divided partial signal groups to form a first delay adding signal;a second delay add processing unit for carrying out a delay add processing to the first delay adding signal output from the first delay add processing unit to form a second delay adding signal; andan image processing unit for reconstructing a three-dimensional image according to the second delay adding signal output from the second delay add processing unit.
