Setting an optimal image parameter in an ultrasound system

摘要

A processor is configured to perform an image process upon an ultrasound image to thereby detect a center of a blood vessel from the ultrasound image. The processor is configured to set the center of the blood vessel as an optimal focal point position. The processor is configured to calculate a plurality of steering angles, a plurality of transmit (Tx) frequencies and a plurality of sound speeds. The processor is further configured to form a plurality of ultrasound images corresponding to each of the steering angles, the Tx frequencies and the sound speeds based on the ultrasound data, detect a signal to noise ratio (SNR), a number of edge points of the blood vessel and a contrast difference between pixels for each of the second ultrasound images to thereby detect an optimal steering angle, an optimal Tx frequency and an optimal sound speed.

1. An ultrasound system, comprising:
an ultrasound data acquisition unit configured to transmit ultrasound signals to a target object including a blood vessel and receive ultrasound echo signals reflected from the target object to thereby output ultrasound data; and a processor in communication with the ultrasound data acquisition unit and configured to form an ultrasound image based on the ultrasound data, perform an image process upon the ultrasound image to thereby detect a center of the blood vessel from the ultrasound image, set the center of the blood vessel as an optimal focal point position, and calculate, based on the center of the blood vessel, a plurality of steering angles and at least one of a plurality of transmit (Tx) frequencies and a plurality of sound speeds, and set an optimal image parameter based on the plurality of steering angles and at least one of the plurality of Tx frequencies and the plurality of sound speeds, wherein the ultrasound data acquisition unit is further configured to transmit and receive ultrasound signals to and from the target object in consideration of the plurality of steering angles and at least one of the plurality of Tx frequencies and the plurality of sound speeds to thereby output a plurality of ultrasound data, and wherein the processor is further configured to form a plurality of ultrasound images corresponding to the plurality of ultrasound data to thereby set an optimal steering angle and at least one of an optimal Tx frequency and an optimal sound speed based on the plurality of ultrasound images.
