[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...

Abstract

An ultrasonic diagnostic apparatus either for displaying three-dimensional ultrasonic images allowing an operator to become aware of the distance of a target object from an ultrasonic probe (1), or for displaying practical three-dimensional ultrasonic images while being simply structured and taking a short time to perform necessary operations. The apparatus comprises: an ultrasonic beam data memory (5) for storing B-mode ultrasonic beam data or CFM ultrasonic beam data; an address control unit (6) for sequentially writing and reading the ultrasonic beam data to and from the ultrasonic beam data memory in the direction of depth; a three-dimensional operation unit (7) for generating three-dimensional ultrasonic beam data using the ultrasonic beam data read from the ultrasonic beam data memory by the address control unit; a three-dimensional ultrasonic beam data memory (8) for storing the three-dimensional ultrasonic beam data thus generated; a DSC (digital scan converter) (9) for converting the three-dimensional beam data to a display-ready format; and a CRT (10).

Description

technical field [0001] The present invention relates to an ultrasonic imaging method and ultrasonic diagnostic equipment, and more particularly, the present invention relates to an ultrasonic imaging method and ultrasonic diagnosis for displaying a three-dimensional ultrasonic target object image, allowing the operator to grasp the distance between the ultrasonic probe and the imaged object equipment, the ultrasonic diagnostic equipment has a simple structure, but can display practical three-dimensional ultrasonic images in a short operation time. Background technique [0002] In order to provide a three-dimensional display of ultrasound images, it involves scanning the inner plane (represented by frames) of the target object with an ultrasound probe. The ultrasound probe is moved in a direction substantially perpendicular to the plane to accumulate ultrasound beam data representing a plurality of frames. [0003] FIG. 1 is a conceptual view of volume data Vo1. A digital s...
