摘要：
Disclosed are a method for estimating the speed of ultrasonic waves, a method and an apparatus for photographing an ultrasonic image using the same. According to one embodiment, the method for estimating the speed of ultrasonic waves includes obtaining ultrasonic waves of a total medium by using reference speed, classifying each medium layer by distinguishing the boundary of the medium layers of the medium from the obtained image, selecting at least two regions of interest (ROI) from different medium layers which are adjacent to each other among the classified medium layers, and obtaining the different speed of the ultrasonic waves in each medium layer by using the wave and depth of the ultrasonic waves in a selected ROI. [Reference numerals] (310) Obtain an ultrasonic image relative to total medium by using one reference speed； (320) Classify each medium layer by distinguishing the boundary of the medium layers of the medium from the obtained image； (330) Select at least two regions of interest(ROI) from different medium layers which are adjacent to each other among the classified medium layers, and obtain the different speed of the ultrasonic waves in each medium layer by using the wave and depth of the ultrasonic waves in a selected ROI； (340) Emit the ultrasonic waves corresponding to each medium layer by using the obtained different ultrasonic waves speed and obtain the ultrasonic image by accessing the beam reflected from the medium； (AA) Start； (BB) End초음파 속도를 추정하는 방법, 이를 이용한 초음파 영상 촬영 방법 및 장치에 관한 기술이 개시된다. 일 실시예에 따라 초음파 속도를 추정하는 방법은, 하나의 기준 속도를 이용하여 매질 전체에 대한 초음파 영상을 획득하고, 획득된 영상으로부터 매질을 구성하는 복수 개의 매질 층의 경계를 식별함으로써 각각의 매질 층을 구분하며, 구분된 매질 층 중 인접하는 서로 다른 매질 층에 대해 적어도 2개의 관심 영역(region of interest, ROI)을 선택하고, 선택된 관심 영역에서의 초음파 속도와 깊이를 이용하여 매질 층 각각에 대한 차등적 초음파 속도를 획득한다.
