Abstract

Disclosed are a three-dimensional (3D) pulsed wave (PW) spectrum ultrasonic diagnostic apparatus and a 3D PW spectrum data generating method. The 3D PW spectrum ultrasonic diagnostic apparatus forms a sample gate in a 3D format by using a two-dimensional (2D) array probe, and generates 3D PW spectrum data by using the formed 3D sample gate.

Claims

a transmitting/receiving unit to transmit a first PW Doppler ultrasonic signal and a second PW Doppler ultrasonic signal to a target object by using a two dimensional (2D) array probe, and to receive a first PW Doppler response signal corresponding to the first PW Doppler ultrasonic signal and a second PW Doppler response signal corresponding to the second PW Doppler ultrasonic signal;

a forming unit to form a sample gate in a 3D format by using the received first PW Doppler response signal and the received second PW Doppler response signal; and

a generating unit to generate 3D PW spectrum data by using the formed 3D sample gate.

2. The apparatus of claim 1, wherein the transmitting/receiving unit receives a plurality of first PW Doppler response signals related to an X-axis section in response to the first PW Doppler ultrasonic signal, and receives a plurality of second Doppler response signals related to a Y-axis section in response to the second PW Doppler ultrasonic signal.

3. The apparatus of claim 2, wherein the forming unit forms the sample gate having a plurality of sections by using the plurality of first Doppler response signals and the plurality of second Doppler response signals to form a cube sample gate.

4. The apparatus of claim 1, wherein the generating unit generates the 3D PW spectrum data with respect to the target object, an amount of the 3D PW spectrum data being equivalent to a width of the 3D sample gate.

5. A method of generating 3D PW spectrum data, the method comprising:

transmitting a first PW Doppler ultrasonic signal and a second PW Doppler ultrasonic signal to a target object by using a 2D array probe;

receiving, from the target object, a first PW Doppler response signal corresponding to the first PW Doppler ultrasonic signal and a second PW Doppler response signal corresponding to a second PW Doppler ultrasonic signal;

forming a sample gate in a 3D format by using the received first PW Doppler response signal and the received second PW Doppler response signal; and

generating 3D PW spectrum data by using the formed 3D sample gate.

6. The method of claim 5, wherein the receiving comprises:

receiving a plurality of first PW Doppler response signals related to an X-axis section in response to the first PW Doppler ultrasonic signal; and

receiving a plurality of second PW Doppler response signals related to a Y-axis section in response to the second PW Doppler ultrasonic signal.
