    摘要： A radiation imaging system is configured by a collimator 30A including a detector 21 with a discrete detection pixel corresponding with a pixel and a plurality of radiation passages 31 and looks into a plurality of detectors 21 through one radiation passage 31 to set a step width of rotation around a rotation center axis X1 only for an angle θp made by lines provided by connecting a center detector 21 of the radiation passage 31 and the adjacent two detectors 21. In the case of generating a flat plane projection image for one direction, radio-graphing is carried out on a projection image in a plurality of predetermined angle positions (−θp, 0, +θp) in the circumferential direction of the rotation center axis X1 and thereby one plane projection image is obtained.

    摘要： In a radiological imaging apparatus, a radiation detecting section includes semiconductor detectors arranged in four columns and four rows. Each of the semiconductor detectors includes a semiconductor base material, and an anode electrode film (first electrode film) and a cathode electrode film (second electrode film) lying opposite each other so as to sandwich the semiconductor base material between them. A first conductive member is installed on each first electrode film. Second electrode films of four semiconductor detectors within a row are connected together using one second conductive member. A shaping amplifier connected to the first conductive members with a wire executes a waveform shaping process using a shaping time shorter than that of a shaping amplifier connected to the second conductive member with a wire; the first conductive members are provided for the four semiconductor detectors within a column.
