Abstract
Provided are an ultrasound imaging apparatus and an operation method thereof for obtaining spectral Doppler pulse wave data at a plurality of points in a region of interest by using a multiline receiving technique, identifying a location and a direction of blood flow by using the obtained spectral Doppler pulse wave data, and automatically correcting an angle of a sample volume by using information about the identified location and direction of the blood flow.
Claims19
A method of correcting an angle of a sample volume based on a direction of blood flow, the method comprising:
- transmitting an ultrasound beam to a region of interest (ROI) including the sample volume in an object and obtaining Doppler data with respect to the ROI based on a plurality of scan lines by using a multiline receiving technique;
- obtaining information about a location and a direction of the blood flow by analyzing blood flow power data with respect to the ROI by using the Doppler data obtained for the plurality of scan lines;
- and
- correcting the angle of the sample volume based on the obtained information about the location and the direction of the blood flow.
An ultrasound imaging apparatus for correcting an angle of a sample volume based on a direction of blood flow, the ultrasound imaging apparatus comprising:
- an ultrasound transceiver configured to transmit an ultrasound beam to a region of interest (ROI) including the sample volume in an object and receive ultrasound echo signals reflected from the ROI along a plurality of scan lines by using a multiline receiving technique;
- a storage storing the received ultrasound echo signals for each of the plurality of echo signals;
- a memory storing at least one instruction;
- and
- a processor configured to execute the at least one instruction stored in the memory to:
- obtain Doppler data for each of the plurality of scan lines based on the ultrasound echo signals stored in the storage;
- obtain information about a location and a direction of the blood flow by analyzing blood flow power data with respect to the ROI by using the Doppler data;
- and correct the angle of the sample volume based on the obtained information about the location and the direction of the blood flow.
