Journal ArticleDOI
A high resolution PET for animal studies
Mitsuo Watanabe,Hiroshi Uchida,Hiroyuki Okada,K. Shimizu,N. Satoh,Etsuji Yoshikawa,T. Ohmura,T. Yamashita,Eiichi Tanaka +8 more
TL;DR: A high-resolution positron emission tomography (PET) system for in vivo animal studies was developed and the physical performance of the system was evaluated.
Journal ArticleDOI
Subset-dependent relaxation in block-iterative algorithms for image reconstruction in emission tomography
Eiichi Tanaka,Hiroyuki Kudo +1 more
TL;DR: The proposed RAMLA using the subset-dependent (dynamic) relaxation 'dynamic RAMLA (DRAMA)' provides a reasonable signal-to-noise ratio with a satisfactory spatial resolution by a few iterations in the two-dimensional image reconstruction for PET.
Journal ArticleDOI
A single-ring OpenPET enabling PET imaging during radiotherapy
Hideaki Tashima,Taiga Yamaya,Eiji Yoshida,Shoko Kinouchi,Shoko Kinouchi,Mitsuo Watanabe,Eiichi Tanaka +6 more
TL;DR: A second-generation OpenPET geometry, single-ring OpenPET, is proposed, which can provide an accessible and observable open space with higher sensitivity and a reduced number of detectors than the earlier one and results indicate that the depth-of-interaction detector can provide uniform resolution even when the detectors are arranged in an ellipsoidal ring.
Journal ArticleDOI
Analytical study of the performance of a multilayer positron computed tomography scanner.
TL;DR: Comparison with experimental data obtained with a head positron tomograph, positologica, showed reasonable agreement both in the total coincidence rates and in the scatter components in the images for a cylindrical phantom of 20 cm in diameter.
Journal ArticleDOI
A high-throughput whole-body PET scanner using flat panel PS-PMTs
M. Watanabe,K. Shimizu,Tomohide Omura,Nakahiro Sato,M. Takahashi,Tsuyoshi Kosugi,K. Ote,A. Katabe,R. Yamada,T. Yamashita,Eiichi Tanaka +10 more
TL;DR: A new positron emission tomography scanner for whole-body studies has been developed that uses coarse septa placed between the block detector rings, which are effective to reduce scattered coincidence events while keeping a high detection sensitivity.
