Title:
画像診断システム及び作動方法
Document Type and Number:
Japanese Patent JP6383355
Kind Code:
B2
Abstract:
An imaging system (200) is configured for grating-based DPCI. The imaging system includes a rotating gantry (204) that rotates around an examination region, a radiation source (208), supported by the rotating gantry, that emits radiation that traverses the examination region, a detector array (212), supported by the rotating gantry, that detects radiation that traverses the examination region, and an interferometer, supported by the rotating gantry, which includes a source grating (214), a phase grating (218), and an absorber grating (220). At least one of the phase grating or the absorber grating continuously translates with respect to the other during an integration period and the detector generates and outputs an electrical signal indicative of the detected radiation, wherein the electrical signal includes an absorption component, a coherence component and a phase component.
