  • Medical imaging apparatus for detection of gamma rays and reflected ultrasonic waves
    Patent number: 7094203
    Abstract: 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: Grant
    Filed: June 21, 2002
    Date of Patent: August 22, 2006
    Assignee: Anzai Medical Kabushiki Kaisha

  • Apparatus for forming radiation source distribution image
    Patent number: 6946659
    Abstract: A radiation source distribution image of an examinee is formed by driving X direction movement motors to move a radiation information-detecting unit in the X direction, and detecting radiation from the examinee on a stretcher placed between guide rails by using a collimator and a line sensor which constitute a detection unit.

  • Apparatus for and method of detecting radiation source
    Patent number: 6635879
    Abstract: 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.
