摘要
We proposed a novel method for extracting the liver region with hepatic lesions inside. The initial liver, obtained by using edge detected image from the subtraction of two different phase images, was used to calculate the mean grey value for the reference of threshold value. The final liver was re-confirmed by thresholding technique. The result showed the effectiveness of our method on 15 cases with liver diseases.
