  • Computer tomography apparatus
    Patent number: 5612985
    Abstract: A computer tomography apparatus of the present invention can select one of an ON state in which X-ray radiation is performed to continuously acquire projection data and an OFF state in which acquisition of projection data is stopped, and even in the OFF state, rotation of an X-ray tube is continued, thus allowing quick switching from the OFF state to the ON state.
    Type: Grant
    Filed: October 24, 1995
    Date of Patent: March 18, 1997
    Assignee: Kabushiki Kaisha Toshiba
    Inventors: Yusuke Toki, Manabu Hiraoka, Ichiro Yamagishi, Hiroyuki Onuki, Tatsuya Ban, Tetsuro Hada, Takeo Nabatame, Masao Yamahana, Masakuni Fujise, Yoshihiko Aochi, Makoto Hayashibara, Masahiro Ozaki

  • Computerized tomographic imaging method and system for acquiring CT image data by helical dynamic scanning
    Patent number: 5412562
    Abstract: In a helical dyamic scanning X-ray CT imaging system, an X-ray source is continuously moved on the same orbit during plural helical scanning operations by controlling a projection direction and a translation of a biological body that is to be examined medically. The helical dynamic scanning X-ray CT imaging system includes a system for helically scanning the biological body as the body is translated along a Z-axis to obtain projection image data of the body along the helically scanned path. Radiation is projected from a radiation source to the biological body being translated along the Z-direction as the radiation source simultaneously moves around the translated biological body. The helical scanning process is carried out during at least first and second helical scanning operations while detecting a radiation angle of the radiation source being detected.
