Patent number: 7094203Abstract: Gamma rays obtained from radioisotope administered to an examinee are detected by a gamma ray information-detecting unit so that a first tomographic image obtained therefrom is formed on a CRT. Further, a second tomographic image of the examinee detected by using an ultrasonic wave information-detecting unit juxtaposed with respect to the gamma ray information-detecting unit is formed while making the second tomographic image overlap on the first tomographic image. Thus, it is possible to obtain a tomographic image in which relative positional relationship of tissue is clear.Type: GrantFiled: June 21, 2002Date of Patent: August 22, 2006Assignee: Anzai Medical Kabushiki KaishaInventors: Tomio Inoue, Tadashi Ito, Masao Jimbo, Takeshi Sasaki, Shuji Tsuchiya, Kenzo Eguchi, Hao Wei, Katsuroh Ohwadano, Hideki Ryuo

Patent number: 6635879Abstract: A small-size gamma camera is capable of reliably and quickly detecting the accumulated position of a radiation source in an examinee. When the examinee is scanned with the gamma camera which has an area sensor comprising 256 (16×16) semiconductor detecting elements, display elements of a display unit on a rear panel of the gamma camera are turned on to display a pattern indicative of the accumulated position of the radiation source. According to the displayed pattern on the display elements, the operator of the gamma camera moves the gamma camera to detect the accumulated position of the radiation source reliably within a short period of time.Type: GrantFiled: June 28, 2001Date of Patent: October 21, 2003Assignee: Anzai Medical Kabushiki KaishaInventors: Masao Jimbo, Takeshi Sasaki, Shuji Tsuchiya, Kenzo Eguchi, Hao Wei, Katsuroh Ohwadano, Hideki Ryuo

Patent number: 4434104Abstract: Disclosed is an improved process for preparing di-lower alkyl naphthalenedisulfonyl by employing a naphthalenedisulfonate chloride and a stoichiometrically excess amount of an aliphatic alcohol and allowing them to react in the presence of an aqueous solution of an alkali. The improved process comprises treating the reaction product from said process with an alkali metal alcoholate and then washing the thus treated reaction product with water to obtain a highly pure product. Also disclosed is a process of limiting the formation of undesirable impurities arising from the reaction of said naphthalenedisulfonyl chloride and said aliphatic alcohol.Type: GrantFiled: June 11, 1982Date of Patent: February 28, 1984Assignee: Nissan Chemical Industries, Ltd.Inventors: Shuji Tsuchiya, Hisao Ikeda, Kenji Suzuki
