Patent attributes
An ultrasound diagnostic apparatus includes: an ultrasound probe capable of 2D scanning and 3D scanning; a transceiver device which drives said ultrasound probe to perform 2D scanning and 3D scanning of the inside of a subject with an ultrasound beam; a storage device which stores 3D data obtained by said 3D scanning; a display device which displays on a display device a 3D image resulting from the projection of said stored 3D data, the position of the 2D scanning plane for Doppler measurement, and a Doppler cursor in a prescribed projecting direction; an instruction-responsive altering device which accepts an instruction from the operator and alters said projecting direction and the position of said Doppler cursor in accordance with the instruction; and a Doppler measurement device which performs Doppler measurement by using the finalized position of the 2D scanning plane for Doppler measurement and the Doppler cursor.
