| Abstract(in English) | In recent years, ultrasound contrast agents have been expanding the possibilities for diagnosis. Subharmonics imaging is one of prospective topics in US imaging techniques. Subharmonic component is expected to realize more high contrast imaging between tissue and blood flow than conventional imaging because it can not be emitted from tissue. In this paper, we firstly inspected the relationship between signal intensity and concentration of contrast agents. On this result, we performed B-mode imaging on phantoms made of agar. In this experiment, three kinds of frequency components, fundamental, secondharmonics and subharmonics, were used respectively. Comparing these images, we confirmed that the image acquired by subharmonics shows less effected from by harmonics from tissue. |
