ULTRASONIC IMAGE DIAGNOSTIC APPARATUS

PROBLEM TO BE SOLVED: To reduce image distortion caused by body motion or the like in three-dimensional image data. SOLUTION: A transmitting and receiving part 2 and a received signal processing part 4 carry out three-dimensional scanning of a wide photography region of a real photographing mode and a narrow photography region of a reference photographing mode which are set with respect to a diagnostic object region of a subject, and collect two-dimensional ultrasonic data at a plurality of scanning parts adjoining in the slice direction. A three-dimensional ultrasonic data generating part 5 generates diagnostic three-dimensional ultrasonic data and reference three-dimensional ultrasonic data by synthesizing the two-dimensional ultrasonic data. A volume data generating part 9 generates volume data by correcting displacement caused by body motion or the like and included in the diagnostic three-dimensional ultrasonic data on the basis of comparison result of the two-dimensional ultrasonic data composing the diagnostic three-dimensional ultrasonic data and the reference three-dimensional ultrasonic data. A three-dimensional image data generating part 10 processes the volume data to generate three-dimensional image data. COPYRIGHT: (C)2010,JPO&INPIT
