Breast and prostate tumors or cancers tend to be stiffer than the surrounding normal tissue. However, the difference in echogenicity between cancerous and normal tissues is not clearly distinguishable in ultrasound B-mode imaging. Thus, imaging the stiffness contrast between the two different tissue...

탄성의 측정은 힘이 가해지는 방향과 변형의 방향에 따라 어떻게 분류되는가? | 탄성의 측정은 힘이 가해지는 방향과 변형의 방향에 따라 종탄성(compressional modulus, Young's modulus)과 횡탄성(shear modulus)값이 있다. Young's modulus는 다음과 같이 정의가 된다. | |
시료를 누르면서 조직의 변형을 측정하여 영상화하는 방법이 빨리 상용화가 될 수 있었던 이유는? | 이들은 시료를 누르면서 조직의 변형을 측정하여 영상화하였다. 이러한 방법은 유방이나 전립선과 같이 접근이 쉬운 위치에 있는 조직의 탄성 특성을 측정하기 용이하므로 비교적 빨리 상용화가 되었다. 실제의 임상에서는 의사가 트랜스듀서를 잡고 진단 부위를 천천히 눌러서 힘을 가한다. | |
탄성 영상에서 변위를 계산하는 방법에는 무엇이 있는가? | 이러한 일련의 과정은 초당 수십 프레임의 속도로 계산하여야 하므로 고속 계산 알고리즘이 필요하다. 탄성 영상에서 변위를 계산하는 방법은 초음파 영상 데이터를 이용한 스페클 추적 (speckle tracking) 방법, rf 데이터에서 혹은 복조한 복소 데이터에서 자기상관, 상호상관을 이용한 계산법, SAD(sum of absolute difference) 등이 있다[12-15]. 변위 계산의 정밀도는 sub-μm 이내의 해상도를 요구하는데 SNR을 높이기 위하여 0. |
