Patent number: 10859512Abstract: Provided is a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject. According to the present invention, it is possible to provide a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject immediately before. That is, the apparatus of the present invention is provided with a phase grating 5 provided with a subject area and a reference area. Both areas each have a predetermined pattern that absorbs radiation, but the patterns are different from each other. In this area, an image of the phase grating 5 is observed in a moire pattern of a long period.Type: GrantFiled: March 15, 2017Date of Patent: December 8, 2020Assignee: Shimadzu CorporationInventors: Koichi Tanabe, Toshinori Yoshimuta, Kenji Kimura, Hiroyuki Kishihara, Yukihisa Wada, Takuro Izumi, Taro Shirai, Takahiro Doki, Satoshi Sano, Akira Horiba

Patent number: 10732132Abstract: [PROBLEM TO BE SOLVED] To provide a radiation phase contrast imaging device having a small device configuration [SOLVING MEANS] The present invention focused on the findings that the distance between the phase grating 5 and the FPD 4 does not need to be the Talbot distance. The distance between the phase grating 5 and the FPD 4 can be more freely set. However, a self-image cannot be detected unless the self-image is sufficiently magnified with respect to the phase grating 5. The degree on how much the self-image is magnified on the FPD 4 with respect to the original phase grating 5 is determined by a magnification ratio X2/X1. Therefore, in the present invention, the magnification ratio is set to be the same as the magnification ratio in a conventional configuration. With this, even if the distance X2 between the radiation source 3 and the FPD 4 is reduced, a situation in which the self-image cannot be detected by the FPD 4 due to the excessively small size thereof does not occur.Type: GrantFiled: February 22, 2017Date of Patent: August 4, 2020Assignees: Shimadzu Corporation, OSAKA UNIVERSITYInventors: Takahiro Doki, Koichi Tanabe, Toshinori Yoshimuta, Kenji Kimura, Akihiro Nishimura, Taro Shirai, Satoshi Sano, Akira Horiba, Takayoshi Shimura, Heiji Watanabe, Takuji Hosoi

Patent number: 10729398Abstract: An X-ray phase contrast imaging device of the present invention can change an arrangement pitch of slits related to a multi-slit and an arrangement pitch of phase shift sections related to a phase grating. A positional relationship among the multi-slit 3b, the phase grating, and an FPD is determined based on the arrangement pitch of the slits related to the multi-slit, the arrangement pitch of the phase shift sections related to the phase grating, and an arrangement pitch of detection elements related to the FPD. Among these arrangement pitches, by changing the arrangement pitch of the slits and the arrangement pitch of the phase shift sections, the present invention can change the positional relationship among the multi-slit, the phase grating, and the FPD.Type: GrantFiled: July 28, 2017Date of Patent: August 4, 2020Assignees: Shimadzu Corporation, Osaka UniversityInventors: Satoshi Sano, Koichi Tanabe, Toshinori Yoshimuta, Kenji Kimura, Hiroyuki Kishihara, Yukihisa Wada, Takuro Izumi, Taro Shirai, Takahiro Doki, Akira Horiba, Takayoshi Shimura, Heiji Watanabe, Takuji Hosoi
