Abstract:
An ultrasonic diagnostic apparatus, comprising:a receiving unit receiving ultrasound arriving at a detection region defined by a plurality of ultrasonic transducers disposed at respective positions;a weighting processing unit for performing a weighting process for received signals derived in said receiver unit with a plurality of types of weighting functions where an arrangement order of the plurality of ultrasonic transducers is represented by a variable;an arithmetic unit for performing an operation including an arithmetic operation in which a direction or a position of an ultrasonic reflection source within the subject is evaluated in accordance with a plurality of weighted received signals derived through the weighting process of said weighting processing unit, and further generates an image signal representative of an image within the subject based on an operating result obtained when the weighting process is repeated; andan image display unit for displaying an image based on the image signal generated in said arithmetic unit.
