The aim of this paper is to report a newly developed micro-computed tomography system for in vivo use. The system was composed of a micro-focus X-ray tube and an image intensifier (I.I.), both of which rotated around the object stage. A guinea pig and a rat were examined. The anesthetized animal was set on the secure object stage. Images of the head of the(More)
Studies show that the radiation dose received during a micro-CT examination may have adverse effects on living subjects. However, the correlations between the biological effects and the radiation doses have never been thoroughly evaluated in the majority of cases. In this study, we evaluated the biological radiation effects of measured radiation doses in(More)
We have been developing a pulmonary circulatory assist device using shape memory alloy fibres for Fontan circulation. It consisted of several shape memory alloy fibres, which covered the ePTFE conduit circumferentially. We designed the sequential motion control system for pulsatile flow generation for sophisticated pulmonary hemodynamics. In order to(More)
