摘要： An X-ray CT apparatus includes a scanner mounted with a detection system having an X-ray source for generating X-rays applied radially to an object and a detector arranged so as to be opposite to the X-ray source and adapted to detect the image of the transmitted X-rays transmitted through the object, wherein the scanner is rotated around the object. A three-dimensional X-ray absorption coefficient distribution image of the object is reconstructed from the transmitted X-ray image and the rotation-axis projection position which is the position where the rotation center of the scanner is projected on the detection plane of a two-dimensional sensor constituting the detector is decided. On the basis of the contrast of the X-ray absorption coefficient distribution image reconstructed by using the decided rotation-axis projection position, the rotation-axis projection position is estimated, and an X-ray tomographic image or/and a three dimensional X-ray image of the object is generated.

摘要： When the laser-stimulable phosphor plate of an information reading apparatus for radiation image is constituted of CsI as the base and 0.0003 to 0.03% in atomic ratio of Na, the output signal of the information reading apparatus can be increased and the decay time thereof can be shortened. When output signals are produced by detecting fluorescence emitted from a fluoroscopic plate disposed in confrontation with the laser-stimulable phosphor plate, there is provided an information reading apparatus for radiation image having an improved S/N ratio and a high efficiency of taking in laser-stimulated luminescence. Further, instead of Na or together with Na, there may be added at least one element selected from the group consisting of Li, K, Rb, Cu, Au, Be, Mg, Ca, Sr, Ba, Zn, Cd, Hg, B, Al, Ga, In, Tl, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Si, Ti, Zr, Ge, Sn, Pb, As, Sb, and Bi.
