R. Yamada,M. Watanabe,Tomohide Omura,Nakahiro Sato,K. Shimizu,M. Takahashi,Kibo Ote,A. Katabe,Takahiro Moriya,K. Sakai,T. Yamashita,Eiichi Tanaka +11 more
TL;DR: A small animal PET scanner using 256-channel PS-PMTs has been designed, constructed, and evaluated and the applicable imaging capability of the scanner was demonstrated by animal studies with a rat.
Patent
Radiation-measuring apparatus employing variable rate pulse sampling control
TL;DR: In this article, a scintillation type radiation-measuring apparatus comprising a radiation-detecting scintillator, wherein a scindillation given off from the scindillator is converted into current by a photomultiplier tube, is described.
Patent
Radiant ray detector
TL;DR: In this article, the authors proposed to increase the propagation efficiency of light between the scintillator and the photo detector by forming the silicon nitride film on the inorganic scintillation surface with plasma glow discharge.
Journal ArticleDOI
A 2D/3D hybrid PET scanner with rotating partial slice-septa and its quantitative procedures.
TL;DR: A 'summation method' is proposed as a new image reconstruction algorithm, in which the high- and low-frequency components of images are reconstructed from the 3D and 2D data respectively, which is expected to be robust for scatter from outside the axial field of view.
Journal ArticleDOI
Time-of-flight positron imaging and the resolution improvement by an iterative method
Masahito Yamamoto,Norimasa Nohara,Eiichi Tanaka,Takehiro Tomitani,Hideo Murayama,N. Sato,T. Omura,Y. Tsuchiya +7 more
TL;DR: In this paper, a simple time-of-flight (TOF) positron imaging method is proposed in which the spatial resolution obtained with TOF information is improved by a novel iterative algorithm.
