  • Publication number: 20080077011
    Abstract: An edge between a tumor and a normal tissue is detected even when acoustic impedance and elasticity of those are not changed. An edge position of tissue is estimated by setting a plurality of estimation regions of an inspection object, detecting direction of motion of the inspection object within each estimation region, and computing the point of inflexion in the direction of motion. Moreover, these edge positions are overlapped on the cross-sectional images and thereby an operator can easily detect the edge lines.

  • Publication number: 20080004713
    Abstract: The present invention can be used for actual implantation surgery without a scaffold. The present invention provides a synthetic tissue or complex which can be produced by culture and has a high level of differentiation ability. The present invention also provides a therapy and medicament for repairing and/or regenerating tissue using replacement and covering. By culturing cells under specific culture conditions such that medium contains an extracellular matrix synthesis promoting agent, the cells are organized and are easily detached from a culture dish. The present invention was achieved by finding such a phenomenon. In addition, the self contraction of the tissue can be regulated by culturing the tissue in a suspended manner. Therefore, it is possible to regulate the three-dimensional shape of the tissue.
