Journal ArticleDOI
Robot system for preparing lymphocyte chromosome.
TL;DR: A culture and harvest robotic system (CHROSY) for preparing lymphocyte chromosome was developed based on the modified method for automatization of the scoring of chromosome aberrations in radiation dosimetry.
Journal ArticleDOI
Measurement of bulk etch rate of CR-39 with atomic force microscopy
TL;DR: In this paper, a simple method for direct measurements of the bulk etch using atomic force microscope (AFM) observations of minute tracks ( ⩽ 1 μ m) in the CR-39 track detector is developed.
Journal ArticleDOI
Positologica: A Positron ECT Device with a Continuously Rotating Detector Ring
Norimasa Nohara,Eiichi Tanaka,Takehiro Tomitani,Mikio Yamamoto,Hideo Murayama,Yoshio Suda,Masahiro Endo,Takeshi Iinuma,Yukio Tateno,Fumio Shishido,Kenji Ishimatsul,Ken Ueda,Katsumi Takami +12 more
TL;DR: A rotary positron emission computed tomography device is developed for human brain and animal studies that utilizes 64 rectangular BGO detectors arranged at unequal spacing on a circular ring for high detector redundancy.
Journal ArticleDOI
Atomic force microscopic analyses of heavy ion tracks in CR-39
Mikio Yamamoto,Naoki Yasuda,M. Kurano,Tatsuaki Kanai,Akira Furukawa,N. Ishigure,Koichi Ogura +6 more
TL;DR: In this paper, the track evolution for high energy C and Si ions in CR-39 was studied using an atomic force microscope (AFM), and the image processing method of AFM observations and the 3D images of C and SI tracks were reported.
Journal ArticleDOI
"Positology"-the search for suitable detector arrangements for a positron ECT with continuous rotation
Eiichi Tanaka,Norimasa Nohara,Mikio Yamamoto,Takehiro Tomitani,Hideo Murayama,Kenji Ishimatsu,Katsumi Takami +6 more
TL;DR: In this paper, the authors proposed a continuously rotating positron ECT system, in which the detectors are arranged on a circular ring with "non-uniform" spacing so as to provide much finer sampling interval in the projections than the conventional circular ring system.
