Abstract
A method and apparatus for measuring a Doppler signal by using volume data. In detail, the method and apparatus measure a Doppler signal by obtaining a sub volume by using a color component of volume data and locating a sample volume on a scan line of a cell whose corresponding sub volume is scanned.
Claims17
An ultrasound diagnostic method comprising:
- obtaining a sub volume whose Doppler signal is to be measured based on a color component of at least one sliced image by cutting a 3-dimensional (3D) image according to 3-dimensional (3D) volume data of a target in a predetermined direction;
- determining a cell corresponding to the sub volume from among a plurality of cells included in a transducer;
- displaying the at least one sliced image;
- displaying a scan line on each of the at least one sliced image, wherein the scan line is irradiated by the determined cell;
- displaying direction information of the scan line on the at least one sliced image;
- and
- locating a sample volume for obtaining a Doppler signal on the scan line.
