[0053] image 3 An ultrasonic diagnostic apparatus implemented according to a first embodiment of the present invention is sketched. exist image 3 Among them, an ultrasonic diagnostic apparatus 100 includes an ultrasonic probe 1 and an ultrasonic beamformer 2 . The ultrasonic probe 1 transmits ultrasonic pulses to a target object and receives ultrasonic echoes reflected from the target object. The ultrasonic beamformer 2 changes the directions of the ultrasonic beams so as to scan a plane within the target object, and generates signals of the ultrasonic beams in each beam direction. In addition, in the ultrasonic diagnostic equipment 100, the B mode processing device 3 generates B mode ultrasonic beam data according to the intensity of the ultrasonic beam signal; the CFM mode processing device 4 generates CFM mode ultrasonic beam data according to the Doppler component in the ultrasonic beam signal; The beam data memory (cine memory) 5 stores the ultrasonic beam data (that i...

[0074] Figure 11 is a block diagram of an ultrasonic diagnostic apparatus 200 practiced according to a second embodiment of the present invention. In operation, the ultrasonic diagnostic apparatus 200 reads out the ultrasonic beam data from the ultrasonic beam data memory 5 for input into the three-dimensional operation device 21, and at the same time reads out the three-dimensional ultrasonic beam data from the three-dimensional ultrasonic beam data memory 8, and reads out the ultrasonic beam data corresponding to the read out ultrasonic beam data. The three-dimensional operation is performed together with the beam data, which is also input into the three-dimensional operation device 21. The three-dimensional manipulation means 21 is a look-up table (LUT) built in RAM or ROM.
[0075] After the ultrasonic beam data is accumulated in the ultrasonic beam data memory 5, a three-dimensional display command can be issued. This enables the second embodiment, like the first embod...

[0079] Figure 12 is a block diagram of an ultrasonic diagnostic apparatus 300 practiced according to a third embodiment of the present invention. The ultrasonic diagnostic apparatus 300 has a local circuit memory 32 built in the three-dimensional manipulation unit 21 . Using the local line memory 32, the three-dimensional operation device 21 performs three-dimensional operations at a higher speed than before.
