![]() Color Doppler sonographic studies were performed using an HIFU 6150S US imaging unit system and a 2.7-MHz electronic convex probe. The HIFU system (Chongqing Haifu Tech) was used under US guidance. US-guided HIFU ablation assisted using color Doppler flow imaging was performed in 11 patients with small HCC (<3 lesions, <3 cm in diameter). We evaluated the usefulness of color Doppler flow imaging to compensate for the inadequate resolution of the ultrasound (US) monitoring during high-intensity focused ultrasound (HIFU) for the treatment of hepatocellular carcinoma (HCC). High-intensity focused ultrasound ablation assisted using color Doppler imaging for the treatment of hepatocellular carcinomas.įukuda, Hiroyuki Numata, Kazushi Nozaki, Akito Kondo, Masaaki Morimoto, Manabu Maeda, Shin Tanaka, Katsuaki Ohto, Masao Ito, Ryu Ishibashi, Yoshiharu Oshima, Noriyoshi Ito, Ayao Zhu, Hui Wang, Zhi-Biao In addition, RMLP is insensitive to noise and can reduces the color distortion of the fused images on two datasets. The experiment results show that RMLP has best performance in quantitative comparison with other methods. The region level pyramid keeps more original information than the pixel level. Finally, the mask is decomposed into a mask pyramid to supervise region mosaicking on a Laplacian pyramid. Then the density-based region growing algorithm is utilized to segment the focused region mask of each image. ![]() First, the Sum-Modified-Laplacian is applied to measure the focus of multi-focus images. In this paper, a method named Region Mosaicking on Laplacian Pyramids (RMLP) is proposed to fuse multi-focus images that is captured by microscope. ![]() Kou, Liang Zhang, Liguo Sun, Jianguo Han, Qilong Jin, Zilong A multi-focus image fusion method via region mosaicking on Laplacian pyramids
