Modified CEUS LI-RADS using Sonazoid for the diagnosis of hepatocellular carcinoma
Katsutoshi Sugimoto,Naohisa Kamiyama,Tatsuya Kakegawa,Hiroshi Takahashi,Takuya Wada,Masakazu Abe,Yu Yoshimasu,Takeuchi Hirohito,Itoi Takao 대한초음파의학회 2023 ULTRASONOGRAPHY Vol.42 No.3
This review outlines several modified versions of the contrast-enhanced ultrasonography Liver Imaging Reporting and Data System (CEUS LI-RADS) that utilize Sonazoid. Furthermore, it discusses the advantages and challenges of diagnosing hepatocellular carcinoma using these guidelines, as well as the authors’ expectations and opinions regarding the next CEUS LI-RADS version. It is possible that Sonazoid could be incorporated into the next version of CEUS LI-RADS.
Universal Design with Robots for the Wide Use of Robots
Nobuto Matsuhira,Junko Hirokawa,Hideki Ogawa,Tatsuya Wada 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
Home use robots and service robots have been expected for the society of the aging and the falling birthrate. However, a lot of disturbance avoiding the robot’ activities exists in such an environment. Universal Design with Robots (UDRob<SUP>TM</SUP>) has been proposed to cope with these problems in our daily life environment using the concept of universal design. Here, interface designs for mobility, handling, and image processing are especially considered in the concept. Conceptual design of the robot system based on UDRob<SUP>TM</SUP> and the interaction design has been shown here.
Effect of Seeding Layers on Preparation of PLZT Thin Films by Sol-Gel Method
Hirano, Tomio,Kawai, Hiroki,Suzuki, Hisao,Kaneko, Shoji,Wada, Tatsuya The Korean Ceramic Society 1999 The Korean journal of ceramics Vol.5 No.1
$(Pb_xLa_{1-x}) (Zr_yTi_{1-y})O_3$ (PLZT) thin films with electrooptic effect are promising for the optical application such as display or light shutter. However, it is difficult to use inexpensive and transparent glass substrates because the conventional process for preparation of PLZT requires temperatures above $600^{\circ}C$. In order to deposit a perovskite PLZT thin films at low processing temperatures through alkoxide route, we have offered several seeding processes which reduce the activation energy for crystallization. In this study, we optimized the stacking structure of multilayered PLZT for obtaining single phase perovskite at lower temperatures. As a result, ferroelectric PLZT thin films with different compositions were successfully prepared at a temperature as low at $500^{\circ}C$.
