Title (EN) GAMMA RAY DETECTOR AND PET DEVICE EMPLOYING THE SAME
(FR) DÉTECTEUR DE RAYONS GAMMA ET DISPOSITIF PET L'UTILISANT
(JA) ガンマ線検出器及びそれを用いたPET装置
Abstract: front page image
(EN)A medium region (S) is formed by filling a space between an outer tubular body (1a) and an inner tbular body (1b) with liquid xenon (2), and a pair of anode pads (11, 12) are arranged two-dimensionally at the opposite ends of the medium region (S) intersecting the incident direction of gamma rays. An intermediate electrode (10) is arranged between the pair of anode pads (11, 12) and a plurality of photomultipliers (5) are arranged two-dimensionally on the outer tubular body (1a). A gamma ray reaction point in the liquid region (S) is specified based on the signals outputted from the anode pads (11, 12) and the photomultipliers (5).
(FR)Une zone médiane (S) est formée par remplissage d'un espace entre un corps tubulaire extérieur (1a) et un corps tubulaire intérieur (1b) avec du xénon liquide, et une paire de plaquettes d'anodes (11, 12) est disposée de manière bidimensionnelle aux extrémités opposées de la zone médiane (S) en intersection avec la direction incidente des rayons gamma. Une électrode intermédiaire (10) est disposée entre la paire de plaquettes d'anodes (11, 12) et une pluralité de photomultiplicateurs (5) est disposée de manière bidimensionnelle sur le corps tubulaire extérieur (1a). Un point de réaction des rayons gamma dans la zone de liquide (S) est précisé sur la base des signaux émis par les plaquettes d'anodes (11, 12) et les photomultiplicateurs (5).
(JA) 外筒体(1a)と内筒体(1b)との間に液体キセノン(2)が充填されてなる媒体領域(S)が形成され、ガンマ線入射方向に対し交差方向となる媒体領域(S)の両端部に二次元状に一対のアノードパッド(11,12)が配置される。一対のアノードパッド(11,12)間に中間電極(10)が配置され、外筒体(1a)に二次元状に複数の光電子増倍管(5)が設置される。そして、アノードパッド(11,12)及び光電子増倍管(5)から出力されるシグナルから液体領域(S)中でのガンマ線反応点を同定する。
