Patent number: 7105846Abstract: After a syringe containing a radioactive sample therein and housed in a radiation shield case is mounted on a radioactive sample holder and set in a radioactive sample measuring apparatus, an upwardly projecting handle of the radioactive sample holder is depressed to cause a syringe holder base supported on second shafts to lower a flange of the syringe held by the syringe holder base, pulling the syringe out of the radiation shield case. Then, the amount of radioactivity of the radioactive sample contained in the syringe is measured.Type: GrantFiled: May 6, 2005Date of Patent: September 12, 2006Assignee: Anzai Medical Kabushiki KaishaInventor: Kenzo Eguchi

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: 6822237Abstract: After the position of a collimator with respect to a gamma camera depending on the position of a detection plane in an examinee, gamma rays radiated from the examinee are detected by a scintillation detector via a collimator and a scintillator, and a signal from the scintillation detector is processed by a signal processing circuit and then transferred to an image reconstructing unit, which reconstructs a three-dimensional image of the radiation source in the examinee and displays the three-dimensional image on a display unit.Type: GrantFiled: June 28, 2001Date of Patent: November 23, 2004Assignee: Anzai Medical Kabushiki KaishaInventors: Tomio Inoue, Tadashi Ito, Masao Jimbo, Kenzo Eguchi, Katsuroh Ohwadano

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: 4578563Abstract: A steam generator is proposed to spray steam in a beauty shop, a barbershop or the like. In the steam generator, a small amount of water is continuously supplied to a heated vapor assembly and is instantaneously converted to steam. A preparation time can be greatly shortened after the vapor assembly is heated. Thereafter, steam can be stably and continuously supplied. Discharge electrodes are arranged in a steam tube extending from the vapor assembly to effectively ionize the steam.Type: GrantFiled: October 12, 1984Date of Patent: March 25, 1986Assignees: Taishin Electric Ind. Co., Ltd., Toshiba Medical Supply Co., Ltd.Inventors: Kenzo Eguchi, Jiro Kobayashi
