Abstract
Provided is a method of generating an ultrasound image corresponding to a cross-section of interest, which is performed by an ultrasound imaging apparatus. Exemplary embodiments include a method of generating an ultrasound image corresponding to a cross-section of interest of an object by storing ultrasound echo signals respectively corresponding to a plurality of frames that constitute a three-dimensional (3D) ultrasound image of the object, performing beamforming on a focal point on the cross-section of interest of the object, and generating beam focused data for the focal point.
Claims14
A method of generating an ultrasound image, the method comprising:
- storing ultrasound echo signals respectively corresponding to a plurality of frames including a first frame and a second frame that constitute a three-dimensional (3D) ultrasound image of an object;
- determining a focal point on a cross-section of interest of the object;
- generating first beam focused data for the focal point by performing beamforming using first channel data including phase information and being acquired from a corresponding one of the ultrasound echo signals corresponding to the first frame and generating second beam focused data for the focal point by performing beamforming using second channel data including phase information and being acquired from a corresponding one of the ultrasound echo signals corresponding to the second frame which is different from the first frame;
- generating combined beam focused data by combining the first beam focused data with the second beam focused data;
- and
- generating an ultrasound image corresponding to the cross-section of interest by using the generated combined beam focused data, and
- wherein the second channel data is acquired at a time point and a location that are different from a time point when the first channel data is acquired and a location where the first channel data is acquired.
An apparatus for generating an ultrasound image, the apparatus comprising:
- a memory configured to store one or more instructions;
- and
- a processor configured to execute the one or more instructions to:
- store ultrasound echo signals respectively corresponding to a plurality of frames including a first frame and a second frame that constitute a three-dimensional (3D) ultrasound image of an object, the ultrasound echo signals being received from a probe including a plurality of transducers;
- determine a focal point on a cross-section of interest of the object, generate first beam focused data for the focal point by performing beamforming using first channel data including phase information and being acquired from a corresponding one of the ultrasound echo signals corresponding to the first frame, generate second beam focused data for the focal point by performing beamforming using second channel data including phase information and being acquired from a corresponding one of the ultrasound echo signals corresponding to the second frame which is different from the first frame, and generate combined beam focused data by combining the first beam focused data with the second beam focused data;
- and
- generate an ultrasound image corresponding to the cross-section of interest by using the generated combined beam focused data, and
- wherein the second channel data is acquired at a time point and a location that are different from a time point when the first channel data is acquired and a location where the first channel data is acquired.
