A 61 year-old Japanese man had a 3.5 cm in diameter HCC nodule in the liver S3 region. We applied the Live 3D ultrasonography during RFA therapy with a cool-tip needle electrode. The echo guidance facilitated an accurate approach for the needle puncture. The guidance was also useful for confirming, whether an adequate safety marging for the nodule had been obtained. Thus new Live 3D ul-trasonography echo technique appears to provide safe guidance of RFA needles via accurate targeting of HCC nodules, thereby allowing real-time visualize- tion when combined with echo contrast.展开更多

After a summary of data generation and analysis in the observation and modeling efforts related to C. elegans embryogenesis, we develop a systematic approach to model the basic behaviors of individual cells. Next, we present our ideas to model cell fate, division, and movement using 3D time-lapse images within an agent-based modeling framework. Then, we summarize preliminary result and discuss efforts in cell fate, division, and movement modeling. Finally, we discuss the ongoing efforts and future directions for C. elegans embryo modeling, including an inferred developmental landscape for cell fate, a quasi-equilibrium model for cell division, and multi-agent, deep reinforcement learning for cell movement.展开更多
