Patent number: 8653463Abstract: A radiation detection apparatus comprising semiconductor substrates each having a first surface on which a photoelectric conversion portion is formed and a second surface opposite to the first surface; a scintillator layer, placed over the first surfaces of the semiconductor substrates, for converting radiation into light; and an elastic member, placed between a base and the second surfaces, for supporting the second surfaces of the semiconductor substrates such that the first surfaces of the semiconductor substrates are flush with each other is provided. In measurement of the elastic member as a single body, an amount of stretch of a cubic specimen in a direction parallel to the first surface when being compressed in a direction perpendicular to the first surface is smaller than an amount of stretch of the specimen in the direction perpendicular to the first surface when being compressed in the direction parallel to the first surface.Type: GrantFiled: May 18, 2011Date of Patent: February 18, 2014Assignee: Canon Kabushiki KaishaInventors: Satoru Sawada, Masato Inoue, Noriaki Oguri, Shinichi Takeda, Masayoshi Akiyama, Taiki Takei
