摘要： A radiation imaging system includes a detecting unit including a plurality of radiation detecting elements arranged in a plane for radiation detection, a collimator provided with through holes respectively aligned with the radiation detecting elements and opening in an entrance surface such that radiation from a specified direction is selectively made to fall on the radiation detecting elements. A second case joined to a first case fixed to the side surface of the collimator defines a holding chamber G, and a holder holding the detecting unit is placed in the holding chamber G such that spaces that allow the holder to be moved in a plane parallel to the entrance surface are formed between the holder and the second case. A position adjusting mechanism for adjusting the positional relation between the second case and the holder by moving the holder relative to the second case.

摘要： A radiation imaging apparatus comprises display means for displaying an image obtained by imaging an object and light projection means for projecting a light projection mark onto the object, and displays a light projection position on the object onto which the light projection mark is projected on the image. The light projection mark is projected as a line of intersection which is perpendicular to the surface of a detector and at which two planar flat light beams visually intersect each other, and the light projection position on the image is moved according to the movements of the flat light beams. By calculating projected lines obtained by projecting the light projection lines projected onto the object by the flat light beams onto the surface and displaying the projected lines on the image, the light projection position is displayed as a point of intersection of the projected lines on the image.

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： Disclosed herein is a radiation imaging apparatus and radiation-imaging-apparatus-based nuclear medicine diagnosis apparatus having a collimator in which a plurality of rectangular through-holes are arranged in a grid pattern and separated by septa is rotated through a predetermined angle as viewed from above in relation to the layout of a plurality of rectangular detectors that are arranged in a grid pattern. The predetermined angle ranges from 20 to 70 degree and more preferably from 30 deg to 60 deg. With this configuration, the influence of sensitivity variations (moire patterns) that are included in an image picked up due to interference with a collimator when pixel type detectors are used is eliminated.
