X-ray generator
Masahiro Nonoguchi,Masashi Kageyama,Tomohiro Chaki,Masaaki Yamakata,Koichi Kato,Masaru Kuribayashi +5 more
TL;DR: In this article, any one of the following three forms is adopted to control the tube current apart from the electron-focusing control: takeoff electrode is disposed near the cathode and the Wehnelt potential and takeoff electrode potential are controlled independently.
Journal ArticleDOI
Laboratory-based X-ray phase-imaging scanner using Talbot-Lau interferometer for non-destructive testing.
Shivaji Bachche,Masahiro Nonoguchi,Koichi Kato,Masashi Kageyama,Takafumi Koike,Masaru Kuribayashi,Atsushi Momose +6 more
TL;DR: A new algorithm for achieving the function of phase-stepping without grating displacement is developed by analyzing the movie of the moiré pattern as the object moves across the field of view, and the absorption, differential phase, and visibility images are obtained.
Journal ArticleDOI
X-ray phase-imaging scanner with tiled bent gratings for large-field-of-view nondestructive testing
Masashi Kageyama,Kenichi Okajima,Minoru Maesawa,Masahiro Nonoguchi,Takafumi Koike,Manabu Noguchi,Ayuta Yamada,Enji Morita,Satomi Kawase,Masaru Kuribayashi,Yukihiro Hara,Shivaji Bachche,Atsushi Momose +12 more
TL;DR: In this paper, a scanner-type X-ray phase imaging apparatus is developed with a desk-sized compact configuration and a 200mm-wide field of view for the examination of objects carried on conveyor systems.
Patent
X-ray generator and adjustment method therefor
Masahiro Nonoguchi,Manabu Noguchi,Koichi Kato,Nishida Ryuji,Yuji Kusaka,Masashi Kageyama,Tomohiro Chaki +6 more
TL;DR: In this article, an X-ray generator capable of easily measuring a beam size of an electron beam on an electron target, and an adjustment method therefor, is provided, provided that the generator is equipped with an X ray detector.
Journal ArticleDOI
Trochoidal X-ray Vector Radiography: Directional dark-field without grating stepping
Yash Sharma,Yash Sharma,Shivaji Bachche,Masashi Kageyama,Masaru Kuribayashi,Franz Pfeiffer,Tobias Lasser,Atsushi Momose +7 more
TL;DR: In this paper, a method of performing X-ray vector radiography (XVR) of a continuously moving sample without the need of any grating motion is presented. But this method is not suitable for industrial applications such as the scanning of samples on a conveyor belt.
