Abstract: Therapeutic environment is highly developed but increasingly complicated by emergence of a new minimally invasive surgical technique, the development of various diagnostic and treatment equipment. Computer Aided Surgery (CAS) technologies contribute for the advancement of minimally invasive surgery using precise guidance system based on diagnostic imaging and robotics technologies. And it also provide us digital operation room environment, in which we can easily measure and analyze the surgical information. We are developing the technologies for guiding surgeons precisely and technologies for measuring and analyzing the digital information on the surgical navigation system to detect and evaluate the characteristics of surgical procedures and environments and also to predict the future outcome and effectiveness of the treatment. In this presentation, I will introduce our research on surgical navigation, surgical workflow/skill assessment, and surgical robotics based on capturing and processing of intraoperative information, including medical image, video information, and trajectory of surgical instrument in minimally invasive surgery. These technologies will support not only to achieve higher quality of minimally invasive surgery, including preciseness, safety, and reliability, but also to establish new strategy of medical device development, by providing a quantitative and subjective evaluation of the value of medical treatment.

Abstract:99mTchas been utilized as a radioactive isotope in medical applications. The majority of this isotope has been separated from nuclear fission products in testing reactors with highly enriched 235U fuel. However, these reactors have been shut down because of the age and the nuclear security reasons. On the other hand, a nuclear reaction method has been proposed. This method is to irradiate 98Mo by neutrons in a reactor to form 98Mo and then to decay to 99mTc. As the target, MoO3pelletsare required. However, because of the low evaporation temperature (700 oC)and coarse grain size of 98Mo enriched powder, it was difficult to obtain high density MoO3pellets. To overcome this problem, a two-step loading method in pulsed electric current sintering was carried out in this study.
Powder of MoO3with an average grain size of 12.5 m was pressed in a graphite die with a diameter of 20mm. Then, a green compact was initially loaded at 10 MPa and heated in a pulsed electric current sintering apparatus with a heating rate of 100oC/min to 500-600oC in vacuum. After reaching the maximum temperature, the pressure was increased to 40 MPa. After holding the temperature for 5 min, the sample was quenched. For comparison, samples pressed at 40 MPa throughout the process were also prepared. The sintered samples were characterized by powder X-ray diffraction for phase identifications and scanning electron microscopy for grain size measurements.
Relative densities of the sintered MoO3bulks are shown in Fig.1. After sintering at 550 oC, the sintered MoO3bulk had a relative density of 93%,which was higher than the target density (90%) and that by a single-step loading at 40 MPa and 550 oC(78%). This property is good enough for separation of99mTc and recycle of Mo. In the presentation, results on solution and neutron irradiation tests are presented.

Abstract: Some years ago I ventured, as an engineer, into the research world of Life Sciences. To my eyes it appeared as Life Sciences researchers worked backwards compared to what happens in the engineering world. It seemed that their research methodologies had a number of issues that could limit their potential. Nevertheless, I also became aware that a different set of problems arose if my own traditional top-down engineering approach was applied to Life Sciences. In this talk I will discuss how I see the role of Systems and Computational Biology as a fundamental methodological “middle-ground” between these two (apparently) distant worlds. I will discuss the new challenges and opportunities offered by the explosion of "omics" data and the emerging field of Data Science in Computational Biology.
