Enhancing quality of ultrasound spatial compound image based on beam profile in ultrasound system
First Claim
1. An ultrasound system, comprising:
- an ultrasound data acquisition unit configured to acquire ultrasound data for obtaining a plurality of ultrasound images corresponding to a plurality of steering angles;
a storage for storing at least one beam profile indicating a spreading degree of an ultrasound beam according to depth based on at least one focusing point; and
a processor configured to set an amount of blurring corresponding to spreading of the ultrasound beam according to the depth based on the at least one beam profile, the processor being further configured to remove the blurring from the plurality of ultrasound images based on the amount of blurring and to form an ultrasound spatial compound image by compounding the plurality of ultrasound images from which the blurring was removed,wherein the processor removes the blurring from respective ultrasound images based on the amount of blurring and a change of pixel values of respective pixels included in respective ultrasound images.
